Irish Moss forms an evergreen mat of mossy foliage that is covered with tiny white flowers in May and June. Prefers good drainage.
Coral Bark Willow ('Chermesina') has stunning orange to red bark coloration in winter on its first year stems, so in order to keep it looking its best, this is a Salix which needs to be cut back hard every spring. The summer foliage is the classic narrow green willow leaf we all know, but its color in the winter landscape will really stand out. Originally introduced from Germany. Wet site tolerant.
'Mt. Aso' Japanese Pussy Willow has beautiful bright pink male catkins appearing in March and April. The fuzzy flowers slowly elongate as they open, ending up almost 2" long by the time the pollen is exposed. Pussy Willows make great cut branches for forcing in January and February, and 'Mt Aso' is a particularly showy form. It is named for Japan's largest active volcano. Cut back the branches to 2' every 2 or 3 years to maintain good catkin production.
PRN Preferred: The prettiest and most showy of the Pussy Willows.
'Swizzlestick' Corkscrew Willow has twisted, upward-reaching orange-yellow stems that display themselves beautifully in fall, winter and spring.

Give it plenty of room in the late summer garden, as it is a sprawler. With lots of mulch, Salvia 'Black and Blue' has been known to overwinter in Zone 6 and 7.
‘Bumbleberry’ Meadow Sage is a new color break from Walters Gardens, producing deep fuchsia pink flower spikes in May and June. The calyxes from which the flowers emerge are dark purple, producing a very colorful effect. The habit is compact, so this Salvia performs well in tight spaces and containers. Deadhead after first bloom flush and enjoy a longer flowering period. Part of the ‘Bumble’ Series,’ as in bumble bees.
Bumblesnow Meadow Sage is part of the ‘Bumble’ series (as in bumblebee) from Walters Gardens. Salvia ‘Bumblesnow’ produces lots of pure white flower spikes in May and June. The habit is compact and the green foliage is disease free and deer resistant. If deadheaded soon after blooming, Salvia ‘Bumblesnow’ will lightly rebloom. Like all Salvias, ‘Bumblesnow’ is a great pollinator magnet.
'Caradonna' Hybrid Sage has violet-blue flowers on tall dark purple flower stems, making a very showy combination. From Zillmer Plants in Germany and introduced into this country by super plant dudes, Dale Hendricks and Ron Strasko while at North Creek Nurseries.
PRN Preferred: Heidi's favorite Salvia because the tall dark purple spikes are so showy.

'Smoke Signal' Little Bluestem is a Walters Gardens introduction, chosen for its vivid coloration in late summer and fall. The foliage is a bluish green in early to mid summer, turning to deep red and purple shades starting in August. The translucent seedheads are an important food source for grassland birds, and the tan stems maintain their upright habit throughout winter. Schizachyrium thrives best in dry, sterile sites, and does not want supplemental irrigation or fertilizer.
‘Standing Ovation’ Little Bluestem is an exciting new introduction by those talented folks at North Creek Nurseries. The steel blue blades are wider than most Little Bluestem. With thicker stems, the habit is reliably upright throughout the summer, fall, and winter. The summer colors of blue with hints of purple turn to spectacular shades of lavender, red, and orange in the fall. The airy seedheads are beautiful, especially when backlit by afternoon light, and the light tan winter color is displayed impressively on the upright strong stems. We find that it tolerates more irrigation than we expected, although its ideal conditions are those of dry sterile sites. One of the native plants chosen by Piet Oudolf for the newly planted meadow garden at Delaware Botanic Gardens.
'Twilight Zone' Little Bluestem is a tall native grass which thrives in dry, sterile locations. This selection was introduced by Walters Gardens because of its vivid coloration, which is visible starting in mid summer, earlier than many Schizachyriums. The leaves and stems sport shades of silver, mauve and purple which become more purple and burgundy as the weather cools. The seedheads appear in early fall and are both beautiful and a source of food for birds. Dry sites are critical to keeping 'Twilight Zone' upright.

‘Night Embers’ Autumn Stonecrop starts blooming in late summer and is topped with mauve pink clusters into the fall. The succulent foliage is a very showy dark purple, held on stiff upright stems. Sedum x ‘Night Embers’ must be in a dry location to perform well, so rock gardens are a perfect location. Another improved plant option from Walters Gardens.
‘Cherry Tart’ Stonecrop comes from Chris Hansen’s Sunsparkler® series of showy Sedums. The succulent foliage keeps its shade of reddish purple from late spring well into the fall. Sedum x Sunsparkler® ‘Cherry Tart’ is crowned with large clumps of bright pink flowers in late summer, attracting butterflies and pollinators. The groundcover habit makes ‘Cherry Tart’ a good addition to rock gardens and dry perennial borders.
'Lime Zinger' Stonecrop is a new addition to the Sunsparkler® series of groundcover Sedums. The foliage has apple-green leaves which are attractively edged with rosy red margins.

'Solar Cascade' Short's Goldenrod is a named selection of our rarest native Goldenrod. Found only in parts of Kentucky and Indiana, it has great drought and sterile soil tolerance. 'Solar Cascade' was chosen for its showy, cascading yellow flowers, as well as its long bloom period in late summer and early fall. It is flourishing in the parking median at the Cincinnati Zoo; 'Solar Cascade' loves the heat and lean soil providing zoo visitors with weeks of blooms. The green foliage is highly disease resistant, so a mass planting of 'Solar Cascade' stays attractive right up until the end of the season. Since it tends to stay in a clump instead of suckering, it also works well in mixed perennial boarders. Hummingbirds and insects love it.
'Golden Fleece' Goldenrod has golden-yellow flowers from mid August to October over semi-evergreen foliage. This Solidago spreads to form a tough adaptable groundcover with some shade tolerance. Another wonderful introduction from the Mt. Cuba folks. Winter birds eat the seeds.

Korean Stewartia features white Camellia-like flowers which appear in June. Based on our experience, the flower of S. koreana is more upright and slightly larger than S. pseudocamellia. Stewartia has exfoliating bark in shades of tan and gray and beautiful burgundy-red fall foliage. A wonderful plant in all four seasons.
Japanese Stewartia is almost identical to Stewartia koreana in habit and exfoliating back characteristics. The only difference we have observed is that Stewartia pseudocamellia's lovely white flowers appear somewhat later in June, and are a little bit smaller. The Camellia-like flowers are accented by showy yellow stamens, and are produced for several weeks. They are a source of pollen for a number of native pollinators, and are followed by interesting printed brown seed capsules in fall. The fall foliage is shades of yellow, red and purple, and the patchy multi-colored bark is beautiful all winter.
