Chenille plant (Acalypha hispida). Shrub; hardy in Zone 11; often grown as a houseplant or an annual in colder areas. The fuzziness of the red catkins comes from the elongated, exaggerated female flowers. Male flowers are borne separately and are nearly inconspicuous.
Lamb's ears (Stachys byzantina). Herbaceous perennial; Zones 4 to 8. Soft, silvery foliage makes lamb's ears a popular plant with gardeners. The white hairs on the leaves help protect the plant from drought stress in its arid native environment of central Asia and the Middle East.
Rosa 'Carefree Spirit.' Shrub; Zones 4 to 9.When it comes to sensuous and silky, you can't do much better than roses. The fine sheen of their petals is best appreciated in species and varieties that have fewer of them. On a sunny day, the light can better reveal the nuances of color.
Stanhopea nigroviolacea. Evergreen herbaceous perennial; Zone 11; grown only in the world's warmest climates, and in conservatories and greenhouses in the United States. One of the oddest orchids around, the stanhopea features an unusually thick, heavy, and waxy central part. The flowers are also extremely fragrant.
Fir clubmoss (Huperzia spp.). Evergreen clubmoss; tender and tropical; exact zones unknown. One of the most stunning and asked-about plants in the New York Botanical Garden's collection, this rare, primitive plant has spore-bearing tassels that resemble the trim on a Victorian lamp.
Cleistocactus icosagonus. Herbaceous evergreen perennial; Zones 10 and warmer; can be grown as a houseplant in colder areas. Many plants in the genus Cleistocactus look friendly and furry, but don't be deceived. Under those fine hairs are extremely sharp spines.
