Cream plumes in the dim corners
White astilbe flowers appear as dense plumes above bronze-green foliage. In low light they seem to glow, which is why they are common in white gardens. Well-known white cultivars include 'Deutschland', a compact plant with creamy plumes, and 'Bridal Veil'.
Designing with white
- Combine with hostas, ferns and Japanese forest grass for a lush shade scheme.
- Underplant with white hellebores for winter interest in cold districts.
- Add dark leaved plants, such as heuchera, for contrast.
- Use as a calm background for pink and red astilbe.
What to do when summer heats up
White plumes brown quickly if the soil dries out. Water often during heatwaves, add a thick layer of mulch and give afternoon shade. In Melbourne and Hobart, clumps do well beside a fence on the cool side. In Sydney, keep plants in the shadiest, dampest bed. Canberra frosts kill the top growth, but the crown returns in spring.
Cut flowers and dried plumes
White astilbe can be cut for the vase, where it lasts around five to eight days if stems are kept in clean water. The plumes also dry well, and many gardeners leave them standing for winter display.
White plumes and pets
No astilbe entry turned up in the ASPCA's toxic lists. Chewing is still best avoided, since most plants can upset a stomach.
