Gardeners' Notes:

My original A. rupestris is going on its 6th or 7th. year in my zone 6 garden and I usually get a few reseeders the following spring. I do have to make sure to add some rocks around the base of the crown the first year to keep it from heaving in the early spring freeze/thaw period until the roots develop enough to anchor it well in place.

Named for its great root beer fragrance. Lavender buds give way to salmon-orange flowers that bloom all summer. Attractive blue-green foliage; blooms first year from seed. Fresh and dried leaves are used to season foods and teas. Drought-tolerant.
