Tips for Growing Astilbe glaberrima

Astilbe are well known herbaceous perennials with divided leaves and erect plume-like panicles of tiny white, pink or purple flowers in summer. The old, brown flower-heads remain attractive in autumn before the leaves die back. I have just acquired 2 dwarf plants.

Astilbe glaberrima

  • Astilbe glaberrima var. saxatilis is a rhizomatous, dwarf, herbaceous perennial growing   2- 6″ tall.
  • They typically have glossy bronze-green, deeply divided leaves and short sprays of pink-tinged white flowers. It is also called by its common name,   Rock Astilbe.
  • Plants are clump forming and like water and fertilizer when in growth.
  • Insects are not a problem but powdery mildews may be troublesome.
  • The plants are hardy in most aspects with or without shelter.
  • Any soil will suit as long as it is moist but loam with spring fertilizer helps.
  • Propagate by division in late winter or early spring, pot divisions under glass and plant out in late spring. I intend keeping them in pots
  • Astilbe glaberrima var. saxatilis is deciduous and the leaves are falling from the centre of both these plants.
  • Companion plant Astilbes with Hostas and border phlox, which all like the same damp, shady conditions.
