Gardeners' Notes:

Note: There are evidently two distinct subspecies of this plant, with photos of each being presented as "T. balsamita" on the web. This tends to create confusion:

T. balsamita, var. balsamita - Tansy-like yellow button flowers with brighter, sweet smelling leaves.

T. balsamita, var. camphoratum - Daisy-like flowers with darker, camphorous smelling leaves.

In a southern climate, the plant succeeds in a mostly sunny position with regular watering. The plant responds well to fertilizer.

I've been growing this plant for years because I love the smell of the leaves, which to me smell like old-fashioned men's cologne. My cat also likes to lay amongst its leaves. Although my plants have flowered regularly, I have not found any seeds. They do spread easily by rhizomes, though, and you can dig up a bunch and stick it in a pot or somewhere else in the yard, and it takes to it very well. It prefers full sun where I live (upstate NY).

A herb which has been grown for many centuries and is possibly native to Eastern Europe and Central Asia.

Likes a well drained soil in full sun but if its leaves you want, and to be honest the flowers aren't worth much in the way of ornamentation, partial shade will produce a leafy plant.

It isn't very pretty and its main use fell out of fashion with the appearance of hops. However it still has other uses.

It was used in brewi... read more
