Silver foliage with 3' tall stems topped with broad, sulfur-yellow flower heads. A hybrid of A. x 'Taygeta' and A. clypeolata, introduced by Alan Bloom in the 1950s. An excellent choice for a hot dry site, especially if it's windy. A beautiful cut flower!
Airy plumes with numerous small, barely blue flowers over mint-scented, oregano-like foliage from June to October. Great in rock walls. It does need good drainage. It looks like a small, light blue Heuchera when in flower, which seems like all the time. 2021 Perennial Plant of the Year by the Perennial Plant Association.
Vivid magenta-pink flowers above mounds of large, scented foliage in spring and early summer. An excellent deer-resistant, spreading groundcover for full to part sun areas with the added benefit of lovely red-tinted foliage in the fall.
The darkest, truest purple flowers to come out of Mt. Cuba’s bee balm evaluations—this selection has upright rigid stems, strongly verticality, and a rough, sand-papery texture to its foliage. Very resistant to powdery mildew.
Aaaarrrrgggghhhh! Named after the infamous English pirate Blackbeard, Penstemon 'Blackbeard' has the darkest of eggplant foliage with bright lilac-purple flowers rising high above and standing tall. With a long season of interest and a magnet for hummingbirds and bees, this Walters Gardens introduction is sure to cause a delightful cry of 'Shiver me timbers!'
Grown mainly for the foliage, 'Purple Knockout' has compact basal rosettes of shiny burgundy leaves that turn to deep purple in summer, then to red in the fall. Spikes of pale lilac-blue flowers appear in spring and summer, but sometimes the flowers have only calyces and no petals. We have not been able to determine the cause of this, but a cut back of the stems promotes new blooms that often have petals the second time around. Petals or no, the flowers are attractive to bees and butterflies. Very easy to grow in just about any soil, it will self sow to spread and become a dense groundcover that makes a great native substitute for Ajuga.
Sedum kamtschaticum var. floriferum 'Weihenstephaner Gold'
Common Name: stonecrop
A favorite among the groundcover sedums, this one is covered in canary yellow star-shaped flowers in late spring. Tough and easy to grow, it survives in just about any sunny location and spreads slowly to form a lustrous green groundcover.
