Astragalus is a perennial that grows up to one foot tall. The plant requires dry, well-drained soil and plenty of sun. Angelica isn’t often used alone but is more commonly mixed with other herbs. Once planted, the roots are very sensitive to relocation, so the plants must grow undisturbed over four to five years before the roots are ready for a fall harvest.
The dried root powder may be used as a tea, an extract, or mixed in various foods. It has a mild, sweet flavor.
