Indian Rhubarb is an unusual dramatic foliage perennial which also has attractive pink flower clusters in April. The delicate flower clusters emerge on hairy stems before the leaves emerge, and are retained for a long period. The round lobe leaves are very large and broad, and have been likened to inside-out umbrellas. Darmera peltata has a thick rhizomaceous root system, and since it thrives in very wet sites, it works well as a stream stabilizer. The fall color of the foliage is often red. This is one of Jerry Fritz's favorite plants for its dramatic appeal. Umbrella Plant is a West Coast native. It will tolerate full sun if planted in a wet site.
Cooper Hardy Ice Plant has magenta flowers over silvery evergreen succulent foliage. Delosperma cooperi needs full sun and a dry site and is perfect for the xeriscape landscape. We are impresses with its cold hardiness in our display beds, and it blooms throughout the summer starting in late June into fall. Avoid planting in heavy soils or soils with poor drainage.
Fire Spinner™ Ice Plant has truly amazing flowers, with multiple flat petals that start orange at the outer edges and end up magenta at the base. Starting in early June, Fire Spinner™ blooms for a month on every sunny day over the attractive fleshy green succulent foliage. Found at high altitudes in southern South Africa, Delosperma dyeri Fire Spinner™ was brought to the US by Panayoti Kelaidis of the Denver Botanic Garden. Rock gardens and green roofs are great places to use this eye opener.
Tall Blue Larkspur is a Delphinium that actually thrives on the East Coast! This native woodland plant blooms in mid summer, with tall spikes of deep bluish purple flowers which are an important source of nectar for hummingbirds.

Hay-scented Fern has lacy green foliage that will take somewhat dry, relatively sunny sites. Dennstaedtia punctilobula is a deciduous spreader that can handle poor soils well. When the fronds are brushed against, they release the smell of fresh cut hay. Native to open woods and wooded banks in the eastern and midwestern US.
'Goldtau' Tufted Hairgrass is a compact form of this lovely cool season native grass.

PRN Preferred: A three season groundcover shrub, a real garden workhorse. Continues to perform year after year.
Yuki Cherry Blossom® (‘NCDX2’) Slender Deutzia is a color breakthrough by Dr. Tom Ranney of NCSU. Normally a white flowered groundcover shrub, Yuki Cherry Blossom® is covered with delicate soft pink flowers in April and May.

The fall color is bronzy purple, which adds another season of beauty.
Yuki Snowflake® ('NCDX1') Deutzia blooms heavily in April and May, covering this low mounding shrub with a multitude of bell-like white flowers. The delicate green leaves are held on arching branches which root when touching the soil making Deutzia x Yuki Snowflake® an attractive shade tolerant groundcover.

'Nikko Blush' Slender Deutzia is a cross made by the US National Arboretum between Deutzia gracilis 'Nikko' and Deutzia x rosea 'Carminea'.

Clusterhead Pinks is a Dianthus oddity hailing from the alpine regions of central and southeastern Europe. Like all Dianthus, D. carthusianorum prefers soil with sharp drainage but the brilliant pink flowers of this gem stand 2-3 feet above the foliage, not unlike one of our favorites Verbena bonariensis. Equally at home in a prairie or rock garden, this exciting Dianthus species deserves much more attention that it currently gets in the trade. It probably owes its name to the Catholic order of the Carthusians, who cultivated it early on in their monastery gardens and as medicinal plant.

Dicentra eximia starts flowering in late spring and continues blooming well into the summer, especially if the weather is cool. A native wildflower of the eastern United States that typically occurs on forest floors, rocky woods and ledges in the Appalachian Mountains. The ferny foliage is attractive all summer, unlike Dicentra spectabilis. Under moist conditions Fringed Bleeding Heart will often rebloom into late summer, especially if deadheaded. It spreads by self-seeding and seed dispersal by ants. It grows best in well drained shady locations. Visited by hummingbirds and long tongued native bees.
The pink and white flowers of Bleeding Heart have a long bloom period in late spring. The entire stems can be used for cut flowers, lasting up to 2 weeks in a vase. Foliage fades away by late summer.

All Dicentra spectabilis cultivars tend to go dormant in the hot summers, but the foliage will sometimes reemerge as the weather cools down. The new name is Lamprocapnos spectabilis ‘Ruby Gold.’
A wonderful improvement over the typical species, 'Valentine' Bleeding Heart produces deep red flowers as opposed to the soft pink of straight Dicentra spectabilis. The foliage is beautifully and deeply dissected and is accompanied by arching stems of stunning red flowers in late spring. Like the species, expect Dicentra spectabilis 'Valentine' to look like it has seen better days as the summer progresses so be sure to plant material around it that can mask its tired appearance.
‘White Gold’ Bleeding Hearts combines the vivid yellow foliage of Dicentra ‘Gold Heart’ with the classic pendant heart-shaped flowers, in white. Dicentra spectabilis ‘White Gold’ appeared as a spontaneous seedling in the garden of Margaret Dalton in New York.

‘Pink Diamonds’ Fern-leaved Bleeding Heart is an introduction from Walters Gardens with both showy flowers and foliage. The fern-like leaves are steely blue, and the two-toned pink heart-shaped flowers bloom from late spring through most of the summer. Dicentra x ‘Pink Diamonds’ thrives in sunny locations with good drainage, as well as partial shade sites. Since ‘Pink Diamonds’ comes from alpine Dicentras, it is very cold tolerant, and should be a good addition to roof gardens.
Gas Plant is a beautiful long-lived perennial for well-drained sites; sporting many showy, mauve pink flowers on tall spikes in June for an extended show. Dictamnus is slow to become established, but once started it becomes a large mound which puts out increasing numbers of flower-topped shoots every year. It has zero tolerance for transplanting, so pick your site well. The common name refers to the theory that it contains enough volatile oils to be lit by matches; but, as Dr. Alan Armitage so eloquently comments, this is not an achievable activity.

Brilliance™ Autumn Fern was selected for its striking new fronds which emerge throughout the spring and summer in shades of salmon, copper and orange. The semi-evergreen fronds then mature to glossy medium green, adding a bright note to woodland settings. Since Autumn Ferns spread slowly by rhizomes, they make a good groundcover in shady sites. Consistent moisture is needed to promote new frond production.
PRN Preferred: Bronze new growth all spring and summer. Looks good throughout most of the winter.
Robust Male Fern has dark green foliage, and does well in deep shade, as well as in sun. Dryopteris filix-mas is a deciduous clump. Highly adaptable because it is relatively sun tolerant. Dryopteris filix-mas is refered to as Male Fern because it was thought to be the male version of Athyrium filix-femina (Lady Fern).
Evergreen Wood Fern has dark green, leathery foliage and tolerates relatively dry sites and deep shade. Dryopteris marginalis is an evergreen clump that performs well on forest edges. The foliage remains green through much of the winter, dying back in early spring as new fiddleheads emerge.
‘Jurassic Gold’ (‘Hollasic’) Wallich’s Wood Fern has amazing spring fronds in shades of yellow, gold and orange. The semi-evergreen foliage matures to bright green in summer, forming an attractive clump that lights up shady locations. Dryopteris ‘Jurassic Gold’ is named for is named for the Jurassic Coast in Southern England, but I assume that is also a nod to the fact that Ferns are a very ancient plant group. The very striking fronds make ‘Jurassic Gold’ a good container candidate for shady locations.
