Opuntia ellisiana Burbank Spineless (Prickly Pear)
Sun Zone: 7-10, possibly colder 36" tall Origin: USA Hybrid
The late Luther Burbank hybridized a number of wonderful plants, and one of our favorites is the spineless prickly pear. For us, this fast-growing but compact opuntia makes a 6' wide mound (in 5 years) of 6" grey-green pads. In August, the clump is topped with large, bright yellow flowers, followed by large red "pears." Well-drained winter soils are vital for best performance. Pot size: 24 fl. oz (709.77 ml) #05564

Orostachys aggregata (Orostachys)
SunZone: 5-8, at least 4" tall Origin: Japan
Web-Only!
(syn: Sedum aggregeatum) Native to seaside rocky areas around Honshu, Japan, this easy-to-grow, rosetted succulent forms low clumps of fleshy-green, rubbery foliage. The main rosettes offset well via short 1"-2" white stolons. In fall, the clumps are topped with bizarre little flower heads that resemble erupting volcanos. Orostachys are easy-to-grow gems for the well-drained rock garden...expect a 1' wide mass in 2-3 years. Pot size: 24 fl. oz (709.77 ml) #00494

Osmunda cinnamomea (Cinnamon Fern)
Part Sun to Light ShadeZone: 3-9 36" tall Origin: USA
Web-Only!
This deciduous NC native is one of our most stately large ferns. The upright clumps thrive in moist soils but also grow well under typical garden conditions...a great large foil in woodland settings. The fertile fronds arise in spring just above the sterile foliage as a phallic, cinnamon-colored spike in the center of the clump. In moist soils, a happy clump of cinnamon fern can reach 3' tall x 3' wide. Pot size: 24 fl. oz (709.77 ml) #01366

Othonna

Othonna cheirifolia (Barbary Ragwort)
SunZone: 7b-8, at least 6" tall Origin: North Africa
This evergreen native to the African countries of Algeria and Tunisia is still little known in the US, despite being used extensively by the late UK Garden designer Gertrude Jekyll in the early 1900s. I dare say this is the only native to North Africa that we grow, but it is one that has performed amazingly well through both our hot, humid summers and cold, wet winters. The tight mats, whose foliage resembles tiny upright silver-blue coke spoons, are topped by 8" tall flowers stalks of yellow daisies in late spring. Othonna cheirifolia is right at home sited in a hot sun, well-drained rock garden or in a drought-prone seasonal container planting in colder climates. Pot size: 24 fl. oz (709.77 ml) #06675

Oxalis (Oxalis)
While oxalis are best known for the weedy members of the family, there are an equal number of non-weedy fabulous garden plants. These easy-to-grow and easy-to-share bulbous plants make great accent plants for rock garden-type settings. |
Oxalis regnellii 'Jade' (Jade False Shamrock)
Sun to Part SunZone: 7-9, at least 4" tall Origin: S. America
Web-Only!
This wonderful new selection of the clumping (non-weedy) Oxalis regnellii has lovely pewter leaves on a 4" tall x 8" wide deciduous clump topped, starting in early spring, with bouquets of pure white flowers held just above the foliage...simply exquisite! Pot size: 24 fl. oz (709.77 ml) #07117
|
Oxalis regnellii 'Silver Shadow' (Silver Shadow False Shamrock)
Sun to Part SunZone: 7b-10, possibly colder 12" tall Origin: S. America
Web-Only!
Oxalis 'Silver Shadow' is a sport that we originally discovered on Oxalis 'Jade'. The pewter leaves, flushed purple underneath, are highlighted by an irregular green speckled edge pattern. The non-invasive, 1' tall x 1' wide, deciduous clump emerges in mid-spring and is topped all summer with small white flowers held just above the foliage...a great textural element in the garden. Pot size: 24 fl. oz (709.77 ml) #07118

Oxalis regnellii 'Triangularis' (Purple and Black False Shamrock)
Part Sun to Light ShadeZone: 7-10, possibly colder 8" tall Origin: S. America
What a charmer! This clump-forming oxalis (not a weed...never seen a seed, indeed!) has deep, velvety purple leaves edged with a wide black border, topped by tiny, light pink flowers in summer...extremely cute! Purple shamrock is a dynamite plant to blend into the perennial border or woodland garden. Some of our Zone 6 customers claim to be growing this successfully through their winters. Pot size: 24 fl. oz (709.77 ml) #00589

Paeonia (Peony)
Our trials for peony heat-tolerance have provided some amazing results. Not only are some of the wild species proving to be well adapted, but several of the peony cultivars, especially those with P. lactiflora bloodlines, are doing amazingly well. We will continue to expand our listing of these great garden plants so gardeners who have been transplanted to the southern states can continue to grow (and flower) their peonies. |
Paeonia 'Bartzella' (Bartzella Intersectional Peony)
Sun to Part SunZone: 4-8, at least 36" tall Origin: Hybrid
Paeonia 'Bartzella' is the Rolls Royce of peonies, and we are thrilled to have enough of this splendid intersectional (herbaceous x tree) peony to share. This stunning hybrid goes dormant to ground level and buds like a herbaceous peony but has flowers and foliage like a tree peony. Developed by peony breeder Roger Anderson of Wisconsin, established clumps of P. 'Bartzella' can reach 3' tall x 3' wide with up to eighty 9" wide, fully double yellow flowers. The flowers don't fall over in the rain like herbaceous peonies, and their opening is staggered over a 6-week period. Our offerings are huge flowering-sized plants. Pot size: 2 Gal #07187

Paeonia 'Cora Louise' (Cora Louise Intersectional Peony)
SunZone: 4-8, at least 24" tall Origin: Hybrid
This 1986 introduction from WI breeder Roger Anderson combines the best of herbaceous peonies with the color, style, and sturdy stems of tree peonies. This intersectional hybrid makes a 2' tall clump, topped in May with huge 10" white flowers, highlighted by a dark maroon central pattern that lightens as it melds into the white body of the flower. Our intersectional peony offerings are all huge, field grown plants. Pot size: 2 Gal #07797

Paeonia japonica (Japanese Peony)
Part Sun to Light ShadeZone: 5-8 18" tall Origin: Japan alternate image
Unlike many of its more common and gaudy cousins, this demure woodland Japanese peony makes an 18" tall x 18" wide clump with grey-green foliage. In early spring, it is topped with lovely, 3" wide white cups fading to a dark burgundy center with yellow stamens. After the flower, the pods split to reveal gorgeous metallic-blue seeds on red stalks. P. japonica is great as a specimen in the woodland garden or scattered throughout the shady perennial border. This is often mistakenly sold as P. ovata 'Alba'. Pot size: 24 fl. oz (709.77 ml) #02397

Paeonia 'Krinkled White' (A.M. Brand 28)
SunZone: 4-8 24" tall Origin: Hybrid
It's hard to imagine, but this 1928 hybrid is still one of the finest peonies on the market...especially for gardeners in the South. This P. lactiflora hybrid boasts very sturdy 2' tall stems, topped in early May (NC) with dozens of large, 6" single white flowers, highlighted by the bright yellow stamens. P. 'Krinkled White' has proven to be one of the top low-chill, heat-tolerant peonies in our trials...simply stunning! Pot size: 3 qt. (2.83 L) #06827

Paeonia obovata (Woodland Peony)
Part Sun to Light ShadeZone: 4-8, possibly colder 18" tall Origin: China, Japan alternate image
We are thrilled to be able to offer one of the most sought-after plants for the woodland garden...the very rare Paeonia obovata. Similar to P. japonica, the stems of grey-green foliage arise in late spring to 18". Topping the stems are marble-sized buds that open to a lovely, single, dark rosy pink flower in mid-May (in NC). P. obovata is a great foliage textural contrast with hostas and ferns in the woodland garden. Pot size: 24 fl. oz (709.77 ml) #02803

Paeonia obovata ssp. obovata var. willmottiae (Chinese Woodland Peony)
Part Sun to Light ShadeZone: 4-7, at least 20" tall Origin: China
We are very excited to offer this little-known form of the prized woodland peony. P. obovata ssp. obovata var. willmottiae hails from 8000'+ on rocky slopes in the mountains of Hubei and Shaanxi provinces. Most of the material sold is Japanese in origin compared to this Chinese form. The variety willmottiae is much more vigorous than typical P. ovata and is topped by single white, cup-shaped flowers about 2 weeks earlier...early April in NC. This is in limited supply, so get them while they last. Pot size: 2 qt. (1.892 L) #06277

SunZone: 4-8, at least 36" tall Origin: Hybrid
This 1996 Roger Anderson intersectional (herbaceous x tree peony) hybrid produces large 10" wide flowers that emerge pastel yellow, highlighted by prominent maroon blotches in the center. As the yellow flowers age, they become suffused with light pink from the petal tips and progress toward the center. Paeonia 'Pastel Splendor' makes a stunning 3' tall specimen with very sturdy stems, occasional reflowering, and great heat tolerance thanks to its tree peony genes. Pot size: 2 Gal #07796

Paeonia 'Red Charm' (L. Glasscock 44)
SunZone: 4-8, possibly colder 36" tall Origin: Hybrid

We are thrilled that this has performed so well in our heat-tolerance trials. Pot size: 3 qt. (2.83 L) #06392

Paeonia 'Scarlett O'Hara' (L. Glasscock - E. Falk)
SunZone: 4-8 36" tall Origin: Hybrid
I was thrilled to find this peony right at the top of the list from our heat-tolerance trials, and with a wonderful southern name, I expected no less. At our May open house, no plant drew more comments than our stunning clump of P. 'Scarlett O'Hara'. The brilliant red, single flowers and contrasting mass of golden stamens on 3' tall stems make this a real attention-getter in the garden. If you have a full-sun garden, you need this peony and yes, we frankly do give a damn. Pot size: 3 qt. (2.83 L) #05652
