Yucca

Yuccas can be found over much of North America, and the architectural assertiveness of their strong, swordlike blades is prized by gardeners. Each year, stout leafless stems bear large clusters of waxy, alabaster-colored floral pendants. Needing little or no maintenance and thriving best in well drained soil, these toughs will not complain where summers are hot or humid, or long and dry. Zone 5/6

Dressed in gray icy greens and powder blues with a dusky purple overlay, this handsome pastel-hued treasure exhibits a tough disposition. Rigid evergreen leaves with sharp pointed tips and fine-toothed margins craft a rounded barrel-like rosette that develops slowly, its amethyst coloration intensifying as the weather heats up. Waxy white pendulous flowers draped on stout panicles deliver late summer sparkle.

Unfazed by mettlesome deer, drought, moisture and humidity, ‘Blue Boy’ can harmonize with Melianthus ‘Antonow’s Blue’ and Festuca ‘Superba’.

Formerly listed as Yucca aloifolia ‘purpurea’.

Blooms July – August.

Size: 4' 0" – 6' 0" high x 3' 0" wide.

Zone 7/8.

<i>Yucca filamentosa</i> ‘Color Guard’

Touted as one of the most attractive variegated Yuccas available, this Japanese cultivar's stiff spiky foliage comprises a mesmerizing close set, evergreen rosette. Achieving an added luster when long, curly white margin fibers seem to capture the moonlight, each spine-tipped leaf is etched by celadon green margins and a bold, creamy gold central stripe, which becomes brighter in mid summer. 'Color Guard's imposing silhouette can stand alone, be juxtaposed with Plectranthus 'Longwood Silver's soft felted foliage or be planted en masse.

Blooms June–July.

Size: 3' 0" – 6' 0" high x 3' 0" – 4' 0" wide.

Hardy to zone 5.

A beguiling sculptural rosette of powder blue, thin pointed blades, year-round good looks and exceptional hardiness is what this shrubby, fine textured Yucca has to offer. Relatively short, flexible leaves forge a luminous specimen well suited for a vessel or the dry garden.

Selected by Sean Hogan of Cistus Nursery from seed he collected in northern Mexico, it will eventually form an upright unbranched plant that prefers to bake in a hot sunny spot with sharp drainage and alkaline soil, while protection from excessive cold-season water and wind helps ensure a successful overwintering.

Blooms July – August.

Size: 4' 0" high x 3' 0" wide.

Hardy to zone 6.

Current Staff's Favorite Plant

Helianthus 'Sheila's Sunshine', Persicaria 'Summer Dance', and Selinum wallichianum

Helianthus ‘Sheila’s Sunshine - P-0461

The sunflower was once an emblem of the Sun God of the Incas. Our sunflowers tolerate a wide range of garden soils, attract bees, and make great cut flowers. Blooms early August – October.

Persicaria ‘Summer Dance’ - P-1312

With foliage that’s close to lime-green, and spiky floral tails that approach the scarlet spectrum of rosy pink, this slow spreading perennial is sure to please. Happiest in semishade with ample moisture. Blooms August–November.

Selinum wallichianum - P-1406

This refined Himalayan beauty happens to be one of our favorite perennial umbellifers. With untold elegance, infinitely divided leaves craft a delicate, lacelike transparency. The compact yet airy green canopy is framed by distinctive, purple-infused branching stems that elevate a charming, late season display of white flattened umbels.

Subduing the riotous array of summertime blooms, it seldom needs staking, and appreciates a well draining moist niche. Blooms June–August.
