The angora-like hairs on this geranium leaf are soft to stroke.
Mint-scented geranium (Pelargonium tomentosum) has large, soft leaves—pale green on top and whitish underneath—covered with long, silky hairs. It reminds me of an angora sweater. With average soil and water, it grows to about 3 feet high and wide. In spring, it bears clusters of dainty, white blossoms. It’s only hardy to Zone 10 (30°F), so treat this frost-tender plant as an annual or grow it indoors in cooler climates.
Another favorite, ‘Powis Castle’ artemisia (Artemisia ‘Powis Castle’), was developed in the cooler, rainier climate of Great Britain. Visitors to my garden can’t pass by it without stroking its finely divided, lacy leaves, with their silky texture and sheen. It sprawls to about 3 feet high and 5 feet wide.
Dittany of Crete, or dittany (Origanum dictamnus), is an ornamental oregano usually grown for its showy bracts. It has soft, furry leaves about the size and shape of a dime. Dittany is low-growing and creeps out about a foot in each direction from its base. Plant it in a hanging pot or let it spill over the side of a raised bed to get the full effect of its cascading branches and to ensure that it gets good drainage. Both dittany and artemisia are only moderately hardy, surviving temperatures down to about 15°F (Zone 8).
