|Tansy, Alecost, Feverfew -- the traditional names for these herbs conjure up a medieval cottage garden. They have been used for centuries to scent closets, flavor ale, soothe stomach-ache, and drive away insects. Hardy perennials, most have button- or daisy-like flowers and aromatic, feathery foliage. Some nurseries may still sell them as Chrysanthemums, so look closely for the second Latin name and common name. Nearly all need full sun and fairly dry soil. Tanacetum balsamita, called Alecost or Mint Geranium, grows denser foliage in partial shade. They can take dry heat and cold, but droop under humidity or dampness. Many self-seed and spread rapidly, so give them room in a wild garden or rocky terrace, or be prepared to curb their growth.
This vigorous, pungent herb spreads as far as you allow it. Hang a bunch in an open window to fend off houseflies. Cuttings boost the mineral content of compost.
