610-021D4     Abutilon 'Marion Stewart'     ( Flowering maple )     
Sun, Part Shade     Zones 8, 9, 10 Orange/Red flowers
It is hard to resist the small, globular flowers that hang like small Tiffany lampshades at the ends of flowering stems. Their golden orange glow is netted with red veining and a long pistil extends far beyond the tip of the almost-closed flower like a pull-cord. The three-lobed foliage is reminiscent of a maple leaf as the common name reminds us. Abutilon 'Marion Stewart' is said to be hardy to 10 degrees Fahrenheit but we treat this as if it were tender and bring it in for the winter.  Late summer, autumn. bloom   6-10 ft. x 4 ft.

Sun, Part Shade     Zones 8, 9, 10 Yellow flowers
Abutilon megapotamicum is popularly known as Trailing abutilon, a name that reflects is growth habit. Altough it is from Brazil, it has proven winter hardy for us, even surviving single digit temperatures with little or no damage. Because it comes back from the roots each year, it rarely reaches its full height. Nonetheless, it blooms well for us. The yellow flowers open down the branches, emerging from much showier, large red calyces. The effect is almost like Christmas ornaments dangling on the tree. You can allow this to trail or tie it up like we do so that the flowering stems are fully visible to visitors.  Summer to autumn. bloom   6 ft. x 6 ft.

610-003D4     Abutilon 'Souvenir de Bonn'     ( Flowering maple )     
Sun, Part Shade     Zones 8, 9, 10 Orange flowers
There is a resurgence of interest in Flowering maples which may be partially due to our continuing interest in exotic-looking plants. Not many named cultivars can claim to have been in the trade for over a century but Abutilon 'Souvenir de Bonn' can do so for it was once popular as a parlor plant in a previous age. Nowadays, it is more likely to be found growing in gardens in warmer parts of North America or grown in a large pot, sheltered during the winter and used to add a tropical look to a summer-to-fall garden. One of its attractions is the large, maple-like leaves which are edged in creamy white. Another, is the large lantern-shaped flowers composed of five over-lapping petals. The petals are salmon orange with dark red veining. Look inside the flower to see the pistil which looks like a fancy gold lamp pull. Don't be afraid to cut this back at the end of winter to force new growth. Keep it well watered and feed it and it will perform well.  Late summer to autumn. bloom   8-10 ft. x 4-6 Ft.

Sun, Part Shade     Zones 5, 6, 7, 8 Lavender Blue flowers
China, Korea, Japan. Hyssops are fine plants for attracting bees and other polinators into the garden. Their rugged, somewhat rounded and toothed leaves are handsome and have a minty aroma when rubbed or crushed. The 4-1/2 inch dense spikes of small tubular flowers are showy over an extraordinarily long season. We have found Agastache rugosa to be a fine plant to naturalize in a meadow garden.  Mid-summer to early autumn. bloom   48 in. x 18-24 in.

156-009     Agastache rupestris       
Sun     Zones 4, 5, 6, 7, 8, 9 Orange/Lavender flowers

342-001D4     Agave neomexicana       
Sun     Zones 7, 8, 9 Yellow flowers
We grow Agave neomexicana in our rockery where its smaller size and colonizing habit seem right at home. The mature rosettes have thick, broad, blue green leaves which are tipped with dark burgundy needle-like points. In ten years this has created many offsets within a yard of the mother plant. In fall, spiders spin fantastic webs between the leaf tips. Needs sharp drainage and full sun.  Summer. bloom   8-10 in. x 12 in.

342-007-1     Agave parryi var. truncata Gentry       
Sun     Zones (8), 9-10 Yellow flowers

The parent plant has broad blue gray leaves with purple black spines at their tips. Orange buds open to reveal yellow flowers. Agave can be sensitive to winter wet, however, they make fine container plants which can be protected from winter rains or excessive cold. We have grown a form of Agave parryi in a hot gravel bed for more than 10 years and it has never suffered.  Summer. bloom   2-3 ft. x 2-3 ft.

555-001     Ajania pacifica f. radiatum       
Sun     Zones 7, 8, 9 White and Gold flowers
For several years we have been confused about this chrysanthemum. From its appearance, we assumed it was a plant that we grew many years ago called Ajania pacifica. But when it bloomed, it does not have the standard clusters of rounded golden flowers we have come to expect from that plant. Instead it has rayed flowers that are white circling the golden centers. We finally consulted Makino's New Illustrated Flora of Japan and found what is called in Japanese "Hana-isogiku" which translates to Chrysanthemum pacificum f. radiatum. It is part of a complex of chrysanthemum that grow on rocks and crags near the Pacific ocean. What we like best about it are the thick, almost succulent leaves which are rich green on top but have dense, fine hairs on their reverses and leaf-edges that make the leaves appear to be out-lined in silver. The plants are somewhat drought-tolerant, can handle sandy soils, and are salt tolerant.  Autumn. bloom

Sun, Part Shade, Shade     Zones 3, 4, 5, 6, 7, 8, 9 Blue flowers
The extra-dark, shiny leaves make this groundcover stand out from other selections of Ajuga reptans. Ajugas are easy-care and can tolerate light foot traffice. Because they do not root deeply, down-sizing and editing is neither difficult not labor-intensive. In the spring, the brilliantly colored flowers of 'Black Scallop' contrast dramatically against the almost purple black foliage. Flowers appear on 6-inch spikes.  Spring. bloom   3 in. x spreading

271-007     Ajuga reptans 'Burgundy Glow'     ( Bugleweed )     
Part Shade     Zones 3, 4, 5, 6, 7, 8, 9 Dark Blue flowers
The rich blue flowers of this bugleweed are shown off beautifully against the mottled foliage of silver, green and burgundy. Even out of bloom, the variegated evergreen foliage is attractive, making this an exceptional groundcover. Even though bugleweed forms a dense cover, it is easy to lift in order to edit or downsize a clump because it does not root deeply.  Spring. bloom   6 in. x 24-36 in.

271-003     Ajuga reptans 'Catlin's Giant'       
Sun, Part Shade     Zones 5, 6, 7, 8, 9 Blue flowers

Sun, Part Shade     Zones 4, 5, 6, 7, 8, 9 Purple Blue flowers
Originating from Valfredda Nursery in Italy, Ajuga reptans 'CHOCOLATE CHIP' ('Valfredda') is a dwarf groundcover that is ideal for smaller gardens. The foliage has chocolate bronze highlights and forms a dense mat that is very low to the ground. In spring, there is a wonderful show of three-inch flower stems above the foliage, but it is really the color of the leaves that sells this plant.  May to June bloom   2-3 in. x 12 in.

289-003     Alchemilla alpina       
Sun, Part Shade     Zones 3, 4, 5, 6, 7 Chartreuse flowers

Sun     Zones 4, 5, 6, 7, 8 Bright Pink flowers
We grow Allium senescens ssp. montanum var. glaucum along our sunny Lavender Walk. Although the flowers make showy, rounded globes, it is the foliage that interests us most. The flattened and somewhat twisted grass-like blades are blue green and form an attractive swirling pattern that enlivens this area for a long time. The foliage has a light onion scent, which makes it resistant to browsing by deer.  July to August. bloom   6 in. x 1 ft.

120-012D4     Allium stellatum     ( Prairie onion. )     
Sun     Zones 5, 6, 7, 8, 9 Rose flowers
Although the standard description of Allium stellatum, a prairie native, says that it blooms after the foliage dies back, our form (perhaps due to our temperate climate) maintains its foliage during bloom. The two-inch rosy globe flowers are produced on and off from midsummer forward.  Mid- to late summer. bloom   8-14 in. x 3-4 in.

120-011D4     Allium taquetii       
Sun     Zones 6, 7, 8, 9 Pink flowers

332-026-1     Alstroemeria 'Red'     ( Peruvian Lily )     
Sun     Zones 7, 8, 9 Rosy Red flowers
For many years we have trialed Peruvian lillies in our garden. They bloom for such a long time that their bright flowers with interesting markings have become a mainstay in our gardens. We acquired Alstroemeria 'Red' from Eidelweiss Nursery in Oregon. We admire the rich rosy primary color of the flowers, the contrasting patch of soft yellow at the base of the petals and the playful dark streaks up the interior to the petals. This clumping perennial has been a fine performer and does not tend to flop in the garden.  Summer. bloom   2.5 ft. x 2 ft.

332-024-1     Alstroemeria 'Red Rose'     ( Peruvian lily )     
Sun     Zones 7, 8, 9 Scarlet flowers
At one time we collected Peruvian lilies to trial them in our garden. We acquired Alstroemeria 'Red Rose' from Buena Creek Nursery in Southern California. This plant stood out because of the scarlet coloration of its flowers. There is a soft yellow patch at the base of the petals and light brown streaking up the interior of the flowers. This sturdy clumper has performed well for us carrying on its colorful bloom well into the autumn.  Summer. bloom   2.5 ft. x 2 ft.

332-022-1     Alstroemeria 'Tricolor'     ( Peruvian lily )     
Sun     Zones (7), 8, 9, 10 Coral Pink flowers
Alstroemeria 'Tricolor' is notable for its exceptionally large flowers and its unique coloration. The three largest tepals of the flower are coral pink with darker interiors. The narrower tepals are white and yellow with burgundy hatch-marks. The foliage is soft green. Take advantage of the long bloom time and enjoy them in bouquets and flower arrangements. The flowers will hold for up to two weeks. These have been reliably hardy in our gardens. Because they bloom such a long time they are ideal plants for incorporating into mixed perennial borders.  Summer. bloom   3 ft. x 1 ft.

725-001-1     Amaryllis belladonna     ( Naked ladies )     
Sun     Zones 7, 8, 9, 10 Pink flowers

The flowers are scented. A Great Plant Picks selection.  Late summer. bloom   2 ft.

272-006D4     Amsonia ciliata     ( Blue milkweed )     
Sun     Zones 6, 7, 8, 9, 10 Periwinkle Blue flowers
We grow several species of Amsonia at the nursery and have had many years to contrast and compare them. Amsonia ciliata is a dramatic perennial with arching stems lined with 3-inch long, narrow foliage that is reminiscent of an ostrich plume. Star flowers are produced at the tips of these stems in great profusion. Late in the summer, interesting narrow seed pods (2 inches or longer) hang from the stems. Of further interest is the autumn color that gilds the leaves golden green with purple brown highlights. The more sun the plant receives, the more dramatic the color transformation. Cut this herbaceous perennial back in early winter or leave the arching stems until your early spring cleanup. This is a wildflower of the southeastern United States. Contrast the size of this to the selection Amsonia ciliata 'Halfway to Arkansas'. A Great Plant Picks selection.  Summer. bloom   4.5 ft. x 6 ft.

272-008D4     Amsonia ciliata 'Halfway to Arkansas'     ( Blue milkweed )     
Sun     Zones 6, 7, 8, 9, 10 Periwinkle Blue flowers
We have grown Amsonia ciliata 'Halfway to Arkansas' for about 6 years. Although it is not really half the size of Amsonia ciliata as its name implies, it is definitely a compact selection that is much shorter in height and spread. The leaves also are shorter but a little wider in comparison with the form of Amsonia ciliata in our garden. They both have an arching habit and similar star flowers in terminal cluster. We grow Amsonia ciliata 'Halfway to Arkansas' in an especially sunny stock field. As a result, it undergoes a dramatic transformation in the autumn when its leaves change to gold with interesting purple brown highlights. One observation we have made is that during our November rainstorms this selection stays more upright than the species. Cut back in early spring.  Summer. bloom   3 ft. x 5 ft.

272-003D4     Amsonia hubrechtii       
Sun     Zones 5, 6, 7, 8, 9 Sky Blue flowers

Sun, Part Shade     Zones 4, 5, 6, 7, 8 Mixed Blues and Whites flowers
We grow Aquilegia 'Woodside Variegata' for the dappled yellow variegation on the green foliage more than the flowers because the leaves remains attractive long after the spent flowers stems have been cut back. Because this grows well in a part shade setting, it is an especially useful addition to the woodland garden. Flowers can be variable in color but this selection seems to produce mostly purple flowers.  Spring to mid-summer. bloom   20 in. x 12 in.

007-013     Arabis ferdinandi-coburgi 'Old Gold'

Use the evergreen Arctostaphylos densiflora 'Sentinel' as a specimen in a mediterranean border. As the shrub matures, older branches develop mahogany coloration. The thickened leaves are loosely adpressed to the stems, revealing their semi-glossy undersides while their downy, matte upper surfaces are somewhat concealed. The pink flowers of spring give rise to dark fruits in summer.  Spring. bloom   4 ft. x 30 in.

410-010D4     Arctostaphylos 'Greensphere'     ( Manzanita )     
Sun     Zones 7,8, 9 Soft Pink flowers
Incredibly dense compact growth makes this selection from Rancho Santa Ana look very unlike a manzanita. This evergreen shrub is rounded in shape much like a box-wood. In spring, clusters of small urn-shaped flowers grace its stems. Customers often ask for small evergreen shrubs that they do not have to prune. This is one of the shrubs we recommend to them as long as we know that they can provide a sunny site with little supplemental water in summer.  Spring. bloom   3 ft. x 3 ft.

410-018D4     Arctostaphylos hookeri 'Monterey Carpet'     ( Manzanita )

Sun     Zones (7), 8, 9 White flowers
For a rockery or sunny slope, evergreen Arctostaphylos 'John Dourley' would be ideal. Young leaves are bronze, thickening like eucalyptis leaves and becoming gray blue as they age. Because of the pink immature stems, the blush on the small bell-shaped flowers, and the outline of red around each leaf, the plant often seems enveloped in a pink haze. In addition to all these features, the mature branches become woody and are clad with patches of mahogany bark.  Spring bloom   15 in. x 6 ft.

In summer, they are followed by surprisingly large red berries. This midsized evergreen shrub is attractive as a specimen or en masse and, because of its width, can even be used effectively as a woody ground cover. Arctostaphylos `Martha Ewan' can be grown in light or partial shade as well.  Early spring. bloom   30 in. x 5 ft.

Sun     Zones 7, 8, 9, 10 Pale Pink flowers
Arctostaphylos 'Sunset' was introduced to commemorate the 75th anniversary of Sunset magazine. This natural hybrid between A. hookeri and A. pajaroensis, forms a midsized, evergreen shrub that has certainly adapted itself to our mediterranean climate. The mid-green leaves are somwhat triangular in shape. In the spring, the new growth is a coppery color and that glow is still evident later as the leaves mature. Many gardeners have used this to make an attractive informal hedge. It can tolerate light pruning but is best left in its natural rounded shape. The clusters of white-with-a-blush-of-pink flowers dangle in clusters early in the season. As the shrub matures, the mahogony bark becomes more evident.  Spring. bloom   3-8 ft x 6-8 ft

The leaves of Artemisia ludoviciana 'Silver Queen' appear more rounded and possibly grayer than 'Valerie Finnis'. In our garden, it is also more upright. We contrast this upright perennial with fiery red Penstemon 'Razzle Dazzle' which helps the dull yellow artemisia flowers look their best.  Late summer to autumn. bloom   36 in. x 24 in.

101-001D4     Artemisia 'Powis Castle'       
Sun     Zones 7, 8, 9 Yellow flowers
Artemisia 'Powis Castle' is a woody perennial with dense clumps of feathery silver foliage. The texture of the leaves makes this an ideal background plant for the dry border where it can complement darker leaved plants.

101-002     Artemisia schmidtiana 'Silver Mound'       
Sun     Zones 3, 4, 5, 6, 7, 8 Yellow flowers
The very dissected, feathery foliage of Artemisia schmidtiana 'Silver Mound' creates a low silver blue mound. Perfect to add both texture and silver into the dry border.

009-018-D4     Asclepias curassavica 'Red'     ( Bloodflower milkweed )     
Sun     Zones 9, 10, 11 Red/Orange Yellow flowers
If only this South American milkweed were reliably hardy in our gardens! The wonderful combination of flower, leaf and stem color makes it hard to resist growing this tender perennial. The red in the name refers to the richly colored rounded buds which appear in clusters of 10 to 20. When the buds open, they reveal flowers composed of five reflexed scarlet corollas that are crowned with a brilliant yellow corona. The lance-shaped leaves are matte green blushed with burgundy. They grow in pairs up dark stems. Late in the season, spindle-shaped seedpods develop bearing seeds with silvery, silky tufts.  Summer. bloom   3-4 ft. x 3-4 ft.

834-003D4     Aspidistra elatior     ( Cast-iron plant )     
Shade, Part Shade     Zones 7, 8, 9, 10, 11 Cream/Maroon flowers
Most commonly we find Aspidistra elatior in the house plant section of a nursery, however, it has proven winter hardy in gardens in the Pacific Northwest and has recently gained a fan club here. Coming from woodland sites in Taiwan and the southern islands of Japan, it is tolerant of low light and seems unphased by irregular watering and moderate cold. Its common name Cast-iron plant comes from its ability to withstand neglect. The evergreen, long-lasting leaves are lance-shaped coming to a sharp point. They arch up from the ground and have a twist or wave toward their ends. Their rich green gloss is a good way to bring reflected light into the garden and their size, although not overly-large (on average about 20 inches long and five wide), focuses the eye in a busy garden much as a mid-sized hosta might. The unusual flowers are up-facing bells at ground-level along the rhizome. Keep the foliage out of strong light to prevent leaf-scorch. And make sure you provide adequate drainage so roots do not rot in water-logged soil.  Early summer. bloom   24 in. x 24 in.

313-002     Asplenium ebenoides     ( Dragons tail fern )

Aster altaicus has ray flowers that range in color from lilac to lavender pink with soft golden central disks. The alternate leaves are mostly entire but occasionally toothed. They are in a whorled pattern up the stems with the largest leaves occuring part-way up the stems and then descreasing in length and width as they climb. This is a fine aster to bridge the gap between the early blooming Aster x frikartii forms and the autumn bloomers. This has recently been renamed Heteropappus altaicus.  June to August. bloom   24 in. x 24 in.

128-049D4     Aster amellus 'Doktor Otto Petschek'

128-053     Aster ericoides 'First Snow'     ( Heath Aster )     
Sun, Part Shade     Zones 4, 5, 6, 7, 8, 9 White flowers
We originally received this as a trial plant with the name Aster 'Glenview' from Intrinsic Perennial Gardens. Over the years, it has become a favorite. Its dense shrubby habit belies it's parentage from the heath aster, A. ericoides. It is ideal on sunny (or part shady) banks like the one where we planted it. There it forms a wonderful cascading cover. When it blooms, it is smothered in tiny white composite flowers. Because Aster `First Snow' blooms later than many perennials, it is a particularly welcome addition to the autumn garden. This has recently been renamed Symphyotrichum ericoides 'First Snow'.  October. bloom   18-24 in. x 40 in.

168-061D4     Aster frikartii 'Jungfrau' (x)       
Sun, Part Shade     Zones 5, 6, 7, 8 Lavender Blue flowers
We would like to thank our garden friend Kelli Dawson for providing this aster to us. We have grown Aster x frikartii 'Monch' for decades and find it to be one of the finest garden perennials we grow. The Swiss hybridizer Carl Ludwig Frikart created several similar crosses between Aster amellus and A. thomsonii but we had never seen any of the siblings of 'Monch' until Kelli gave us 'Jungfrau'. Both are long-blooming and have lavender blue flowers with yellow central disks. How are the two different? In our garden, Aster x frikartii 'Jungfrau' is taller and does not bloom quite as long as 'Monch'. In addition, 'Jungfrau' has semi-double flowers that are 1-1/2-to-2-inches wide while 'Monch' has single flowers. Seen side by side, they are easy to distinguish from each other. ( Both are named for Swiss mountains.)  Midsummer to early autumn. bloom   24-36 in. x 36 in.

Sun, Part Shade     Zones 4, 5, 6, 7, 8 Pink flowers
During Astrantia plant trials at the Closed Loop Garden outside of Olympia, WA, 'Bo Ann' was notable for its large flowers and its pleasing, compact habit. The "flowers," which are composed of slightly ruffled, papery bracts surrounding a central umbel of small five-petalled flowers, persist for a long-time on the stem and retain their attractiveness even as their colors fade. Bees and other polinators frequent them when they are newly opened and later in the season they are visited by birds. The foliage of Astrantia is lobed in a similar fashion to hardy geraniums and is bold and somewhat rugged in appearance.  Early to midsummer. bloom   18 in. x 18 in.

They are tolerant of most soils, hold up well to air pollution and are relatively cold hardy. Many are known for the brilliant gold variegation of their thick leathery leaves. 'Emily Rose' is a mid-sized, unvariegated selection. Its green leaves are large and broadly toothed along their margins. For those that do not like variegation, or simply need a calming green background shrub, this is an excellent choice. Because Aucuba 'Emily Rose' is a female selection it will only produce its scarlet fruit if a male selection is planted nearby.  Midspring. bloom   4-5 ft. x 4-5 ft.

592-007D4     Aucuba japonica 'Gold Variegated Sport'       
Sun, Part Shade, Shade     Zones 6, 7, 8, 9, 10 Red Purple flowers
This was originally sold to us as Aucuba japonica 'Picturata' but it has sported into an entirely different shrub. Recent knowledgeable visitors agree with us that we no longer are growing 'Picturata' which has green leaves that are heavily speckled gold. Our form seems to be the reverse with almost purely gold leaves with green speckles. Young leaves tend to have more green in them, but as the leaves mature the change becomes really evident. We grow this Aucuba japonica in the shade of an English walnut where it has become a glowing, mid-sized shrub. This has never borne fruit because there are no male forms nearby.  Midspring. bloom   7 ft. x 7 ft.

566-003-1     Azara microphylla       
Sun, Shade     Zone 8, 9, 10 Yellow flowers
The small, rounded, somewhat glossy leaves of Azara microphylla are evergreen and create a lace-like pattern against the sky on this narrow upright small tree. Ours is now about 22 feet tall. It is fully tolerant of either sun or shade. The mature bark has patches of gray on brown. On sunny days early in the season, our lavender path smells like a bakery when the tiny yellow flowers emerge and give off their vanilla fragrance in the warming air. A Great Plant Picks selection.  Spring. bloom   30 ft. x 12 ft.
