418-001D4     Olearia macrodonta       
Sun     Zones 8, 9, 10 White flowers
Apparently in the wild Olearia macrodonta can reach 20 ft. in height. We have grown it on our dry sunny hillside for more than a decade and it has never reached more than 7 feet. Its large holly-like leaves are thick and evergreen, but not at all prickly. Their gray green color is a perfect complement to the off-white daisies that generously cover this plant.  Summer. bloom   6-7 ft. x 10 ft.

056-005D4     Ophiopogon japonicus 'Hakuryu' ('Pam Harper')       
Sun, Part Shade, Shade     Zones 7, 8, 9, 10 White to Light Purple flowers
The name of this Japanese selection means "white dragon" which describes the evergreen leaves which are edged in white, occasionally with additional striping or double-striping. This carefree groundcover is so versatile it can grow in sun or shade. The tiny flowers are white or pale purple. Near the end of the autumn, small cobalt fruits appear adding a little late-season zing. This is sometimes sold under the name 'Pamela Harper' the wonderful garden writer and photographer who introduced it to the public.  Early summer. bloom   4 in. x spreading

056-007D4     Ophiopogon japonicus 'Kijimafukiduma'     ( Mondo grass )     
Part Shade, Shade     Zones 5, 6, 7, 8 Pale Lavender flowers
Also known as 'Silver Mist' this diminutive, grass-like, evergreen groundcover has very narrow leaves that are irregularly striped with white lines giving it the misty appearance refered to in its English name. Although Ophiopogon japonicus 'Kijima Fukiduma' may look like grass, it is really a lily relative and should not be mowed. Over time its tuberous roots and stolons will spread out creating a dense cover that is ideal under shrubs and trees. Tiny summer flowers will eventually set dark rounded berries.  Summer. bloom   5.5 in. x Spreading

056-004     Ophiopogon japonicus 'Nanus'     ( Dwarf mondo grass )     
Part Shade, Shade     Zones 7, 8, 9, 10 Lilac flowers
We have seen this low perennial used effectively to create a lush carpet of green under evergreen shrubs in commercial plantings. Because Ophiopogon japonicus 'Nanus' is not a fast spreader, we know this is an effect that has been created over time or by using a large number of plants. We ourselves use it to demarcate an awkward shady turn in a path. The tufts of leathery, dark green leaves form a thick glossy barrier. Occasionally this will send up bloom spikes with tiny orchid-like flowers. Dark fruits develop in the fall.  Summer. bloom   3-4 in. x 4-5 in

056-003     Ophiopogon planiscapus       
Part Shade     Zones 6, 7, 8, 9, 10 Pink Purple flowers
Ophiopogon planiscapus is very much like a Liriope. This rhizomatous lily relative forms evergreen clumps of grassy foliage. The tiny bell-shaped flowers rise on short racemes in summer leaving behind persistent black fruits.  Summer. bloom   8 in. x 12 in.

056-001     Ophiopogon planiscapus 'Nigrescens'     ( Black mondo grass )     
Part Shade     Zones 6, 7, 8, 9, 10 Smoky Pink flowers
Give a kid a new color crayon and watch out. In our garden, the evergreen black strap foliage of Ophiopogon planiscapus 'Nigrescens' is commingled with yellow variegated Arabis ferdinandi-coburgi 'Old Gold', Athyrium nipponicum 'Pictum' and Trifolium 'Purpurescens Quadrifolium'. Inspired customers went wild with their own combinations. A good plant for containers because it is evergreen and seems to compliment just about any companion you can give it. The flowers appear just above the foilage and are followed by shiny dark fruits. A Great Plant Picks selection.  Summer. bloom   18 in. x 12 in.

253-001     Origanum 'Hopley's'       
Sun     Zones 7, 8, 9, 10 Purple Pink flowers
Origanum 'Hopley's' ('Hopley's Purple') is one of our most requested plants. The long wands of flowers retain their color as they dry lending it interest over a very long period. The bees and hummingbirds love it, and so do the small "skipper" butterflies. Sometimes in high summer it seems like the surface of the plant is in motion, there are so many pollinators visiting.  Summer. bloom   2 ft. x 3 ft.

253-017     Origanum 'Jim's Best'       
Sun     Zones 5, 6, 7, 8, 9 Pink flowers
Origanum 'Jim's Best' is an ornamental form of the culinary herb Origanum vulgare. The rounded foliage is misted and streaked with gold which shows off the purple stems and petioles. The pink flowers are contained in persistent purple green bracts.  Summer. bloom   12 in. x 30 in.

253-018     Origanum 'Kent Beauty'       
Sun     Zones 5, 6, 7, 8, 9 Pale Pink flowers
Origanum 'Kent Beauty' is perhaps the most ornamental of all the oreganos and one that we struggle to grow outdoors. It does not like our wet winters, so give it the best drainage possible. The small flowers are embedded in a series of rich pink bracts that are very showy. This little semi-evergreen shrublet has trailing stems.  Summer bloom   4 in x 8 in.

253-006     Origanum majorana 'Variegata'     ( Sweet marjoram )     
Sun     Zone (8), 9, 10 Pale Pink flowers
Origanum majorana 'Variegata' is an attractive form of this well-known garden herb. The small rounded mint green leaves are encircled in creamy white with a pink blush. We grow it near a Salvia officinalis 'Purpurea' where the pink blush echoes the purple foliage of the sage.  Summer. bloom   10 in. x 12 in.

253-002     Origanum vulgare 'Aureum'     ( Golden oregano )     
Sun, Part Shade     Zones 7, 8, 9 Lavender-Pink flowers
Origanum vulgare 'Aureum' is a gold foliaged form of the species with lavender pink flowers. It forms nice clumps that need little maintenance other than removal of the spent flower stems once a year. It appreciates good drainage but is suprisingly tolerant of a variety of soils. Good for attracting pollinators to the garden.  Summer. bloom   12 in. x 12 in.

253-003     Origanum vulgare 'Aureum Crispum'     ( Oregano )     
Sun     Zones 5, 6, 7, 8, 9 Pale Pink flowers
The name says it all. The crinkled gold foliage of Origanum vulgare 'Aureum Crispum' is what distinguishes this aromatic perennial. This seems to get a bit broader than the species. Use the leaves in the kitchen fresh or dried, or grow this for its ornamental value in a Mediterranean style border.  Summer. bloom   12 in. x 18 in.

253-010     Origanum vulgare 'Dwarf Greek'     ( Oregano )     
Sun     Zones 5, 6, 7, 8, 9 Purple flowers
Origanum vulgare 'Dwarf Greek' is a dwarf mounding form with intense flavor that is excellent for cooking.  Summer. bloom   10 in.

253-021     Origanum vulgare 'Hot and Spicy Greek'     ( Oregano )     
Sun     Zones 7, 8, 9 Pink flowers
Origanum vulgare 'Hot and Spicy Greek' was selected mostly for its highly aromatic qualities and its spicy flavor, but it also is worthy of use in a mixed border not only for its fragrance but also for its rich green rounded foliage. Like the other oreganos, pollinators are attracted by the flowers.  Summer. bloom   8-24 in. x 24 in.

253-026     Origanum x majoricum 'Sicilian'     ( Hardy marjorum )     
Sun     Zones 6, 7, 8, 9 White flowers
Known both as hardy marjorum and Italian oregano, Origanum x majoricum 'Sicilian' is a spicy, pungent herb that we have come to enjoy for culinary purposes. Rose Marie Nichols McGee of Nichols Garden Nursery introduced us to this herb when she did a workshop for us. She told us this is the most flavorful oregano she has ever grown and asked us to try it. When she left our nursery, she left behind a tub of useful and attractive edibles built around this oregano. The oregano is still going strong despite several colder than usual winters. And she is right, it is indeed flavorful, combining the robust flavor of its Origanum vulgare (Oregano) parent and the sweetness of its other parent, Origanum majorana (Marjorum).  Early summer. bloom   18-24 in. x 12 in.

253-016     Origanum 'Yellow Flicker'       
Sun     Zones 7, 8, 9 Lilac-Pink flowers
Origanum 'Yellow Flicker' is a Joy Creek Introduction. We found this variegated herb in our gardens. The foliage is irregularly blotched with gold that fades to cream giving an overall tri-colored effect.  Summer. bloom   8 in.

613-001D4     Osmanthus heterophyllus 'Goshiki'       
Sun, Part Shade     Zones 7, 8, 9 White flowers
The Japanese name for Osmanthus heterophyllus 'Goshiki' indicates that it is "five-colored." It is true that the young leaves are pink maturing from light green to dark green with irregular cream-to-yellow splotching. Perhaps the intensely fragrant white flowers are yet an additional color. Their fragrance permeates the garden in the fall. The thick, glossy holly-like foliage may look spiny but it is soft to the touch. A Great Plant Picks selection.  Fall. bloom   3 1/2 ft. x 3-5 ft.

057-007     Oxalis 'Klamath Ruby'       
Shade, Part Shade     Zones 7, 8, 9 White flowers
We have long grown Oxalis oregana as a ground cover in our shade garden, but we were delighted to receive Oxalis 'Klamath Ruby' from fellow nurseryman Sean Hogan. The dark green leaves have burgundy reverses and stems setting it apart from the standard species. The 1/2-inch white flowers have pale pink veining which complements the overall purple tone of the plant.  Late spring to summer. bloom   8 in. x spreading.

057-001     Oxalis oregana     ( Redwood sorrel. Oregon oxalis. )     
Part Shade, Shade     Zones 4, 5, 6, 7, 8, 9 White flowers
NW native. Oxalis oregana is a wonderful, dense, spreading ground cover for woodland gardens. Solitary white flowers. A Great Plant Picks selection.  Spring to fall. bloom   8 in. x indefinite.

057-009Qt     Oxalis triangularis     ( Burgundy Shamrock )     
Part Shade     Zones 6-10 White flowers
Oxalis triangularis has large, bronze purple leaves with flashy red-purple reverses. They fold up like parasols in the cold and open up in the sun. The dramatic trio of leaflets measures more than 3 inches across. Each leaflet has a butterfly shaped stain in the center. Delicate, cupped, white flowers in racemes of 3 and 4.  Summer. bloom   7-10 in. x 7-10 in.

691-002D4     Ozothamnus rosmarinifolius 'Silver Jubilee'       
Sun     Zones 7, 8, 9 White flowers
Many Australian natives are hardy for gardeners in the Pacific Northwest. Ozothamnus rosmarinifolius 'Silver Jubilee' joins the company of plants like Grevillea victoriae and Callistemon 'Woodlander's Red', evergreen shrubs that have become popular in local gardens because of the beauty of their bloom and their textural foliage. As the species name indicates, 'Silver Jubilee' has narrow leaves that are reminiscent of rosemary. The undersides of the leaves are silver and because of the angle at which they are held on the whiteish stems, the shrub looks silver. This was grown from seed that was collected in the wild in Tasmania and raised by a Mr. J. May in the United Kingdom. The flower buds are pink in color and persist for a very long time before they open. The white flowers are held in tight corymbs at the top of the stems. Because of of the silvery cast of its leaves, this is easy to use as a background plant in a full sun, drought tolerant garden.  Summer. bloom   6-10 ft. x 5 ft.
