'Pesto Perpetuo' basil not only produces copious amounts of leaves for cooking but also is easy on the eye. It has creamy white variegated leaves and a columnar habit. It does not flower, so nothing will detract from the foliage.

Ophiopogon planiscapus 'Nigrescens' Ophiopogon planiscapus 'Nigrescens'
(Black mondo grass)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Black mondo grass has straplike, shiny black foliage and grows in little tufts. The grasslike foliage looks good with  chartreuse foliage, variegated woodland plants, and with its own flowers, which bloom in midsummer. Young leaves start out with a greenish hue that soon turns to black. The flowers are bell shaped and can be pink, pale violet, or white, and are followed by fleshy black seeds that may remain on the plant all winter. This perennial is evergreen in mild winters or in the warmer portions of its range. It looks stunning in a shady container planting. -Lou Anella, Regional Picks: Southern Plains, Fine Gardening issue #127

The old-fashioned shamrock house­plant is now high fashion. Several introductions from Proven Winners push this group to the fore for its elegant foliage; abundant, delicate flowers; and vigor. Only 6 to 10 inches high with a spread to 12 inches, this plant’s tiny, ¾-inch-wide, bronze-colored leaf clusters and bright yellow flowers are massed on trailing stems that spill over the sides of shaded window boxes and containers.

It bears usually solitary, single creamy white to pale pink blossoms that are cup-shaped and elegant. The blooms measure 3 to 4 inches across and have pale yellow stamens.

This plant is a beautiful addition to the garden from early spring until autumn.

Each 18-inch stem bears a 2-inch-wide, chalice-like, single pure-white flower with yellow anthers and purple filaments. Mature seedpods open to reveal metallic-blue pea-sized fertile seeds and holly-berry red unfertilized seeds.

Panicum Ruby Ribbons’ soft blue-green foliage emerges in the spring on upright, clumping plants. The foliage takes on a wine-red color in early summer, which intensifies as the season progresses.

The 4- to 6-inch-wide blooms of 'Flamenco Dancer' poppy stand out in late spring and early summer with their true red color and fanciful fringes. It is a sport of the popular 'Turkenlouis'. After the flowers fade, this perennial will go dormant, so plant it near neighbors that will fill the vacancy.
