Astilbes have a long flowering period and are prized for their attractive flower and foliage combinations. They are perfect for adding some much needed colour to shadier areas of the garden. Deeply-cut leaves and feathery blooms add texture and interest to container gardens and cut-flower arrangements. Astilbe ‘Purple Rain’ has fluffy vivid purple flower plumes that rise gracefully above the dark green leaves. Astilbe flowers are tiny, but gather in large, feathery plumes.

Planting Conditions

Astilbe are easy to grow provided you plant them in a partially shaded spot in a soil that retains it’s moisture, but is free draining. They can tolerate being planted in a sunnier position, as long as the soil does not dry out at any point.

Watering & Feeding

During the first season water generously three times per week, until they die down for the winter. Do not let the soil dry out and water more frequently if planted in a container. Add a layer of organic bark mulch in the spring. Astilbe’s don’t like to dry out, so the mulch will help maintain the soil moisture, it also prevents weed growth.

General Care

Apply a slow release fertiliser in spring to help your Astilbe flourish. Removing faded flowers will give a neater appearance, but isn’t essential. Cut plants to ground level in autumn, this will give you the best chance of growing a healthy plant the following season. Astilbes do best when divided every three years – do this by digging the plant up and and cutting the root ball into several pieces.
