Astilbe

Astilbe plant in flower

Long flowering Astilbe are a shade loving perennial that also have attractive ferny foliage. Easy care and an excellent plant for a moist woodland position. They can also be grown in containers where the fine foliage is attractive from spring through to fall.

They are not really an early spring plant, more of a late spring to early summer, with flowers in early summer to mid summer. Some species are quick spreading others are very slow.

Astilbe flowers range from white through to lilac, red and pink. These really are a shade loving plant and given the right growing conditions require little care. Astilbe are also referred to as 'Feather Flower', False Goats Beard' and 'False Spirea'.

Most species prefer a moist part shaded position. A humus rich well dug soil is best. The feathery plumes of the Astilbe Flower are long lasting if planted in part shade, and the foliage will not burn as it will in full sun.

Where are they grown

Generally USDA Zones 3 - 8. They do not like long dry periods in summer, and require protection from freezes in winter.

Astilbe are popular in Minnesota, Vermont, Maine, Wisconsin, Connecticut, New Hampshire, Iowa, Michigan, Illinois, Nebraska, Pennsylvania, Maryland, Washington and Oregon.

Astilbe 'Fanal'

Varieties

Propagation

Propagation is easist by division of larger established clumps. The best time to divide clumps is in spring, although you can divide in fall if you must.

  • Dig the clump with a garden fork.
  • Divide with a sharp garden knife or spade
  • Replant and water in with a liquid seaweed fertilizer, this help reestablish root systems.
