Alumroot (Heuchera cylindrica) is blooming at the nursery and the bees love it!
Alumroot gets its name from the high concentration of tannins in its roots, making it suitable as an alum substitute. Alum has many uses including as a mordant for fixing dyes. Alumroot is compact and tolerant of poor soils making it an excellent choice for rock gardens and edges.
