Water Saving Tip:

Fix leaking sprinklers, valves, and pipes.

One broken spray sprinkler can waste 10 gallons per minute - or 100 gallons in a typical 10 minute watering cycle.

  • Description

  • Notes

'Superba' is a bold, very tall astilbe with dark green, compound, fern-like foliage that grows in mounds to 24 inches tall and wide. Large, dense panicles of rose-purple flowers on hairy stems rise to 4 or more feet ttall in early to mid-summer. Not a low-water plant, but it is typically over-watered, and so could fit into a shady border that is watered weekly during the hottest portion of the summer.
Grow in average to loamy, medium, well-drained soils in part shade to full shade. Prefers moist, humusy, organically rich soils. If regularly watered, foliage will usually remain attractive throughout the growing season. Mulch helps retain soil moisture. Chinese astilbes are generally noted, however, for having better sun and drought tolerance than other species of astilbe. Removing faded flower stalks will not prolong bloom but may improve plant appearance, particularly if a ground cover look is desired. On the other hand, many gardeners leave the flower stalks in place after bloom because of the continuing ornamental interest of the dried seed heads. Divide clumps when overcrowding occurs (every 3-4 years). Not a low-water plant, but one of those that is habitually over-watered.
