Astilbe

A genus of herbaceous perennials that are popular as landscape plants in temperate climates around the world. Astilbes looks great in the woodland garden and some of the larger ones also look great planted next to water with Darmera peltata and some of the larger leaves Hostas.
Astilbe's prefer partial to full shade ( tolerant of sun in cool climates ) on moist to wet soil. Astilbes respond well to fertilizer during early spring, right after blooming then with a high phosphorous application for the roots during early autumn.
Cutting off old faded flower spikes and the occasional tired looking leaf greatly improves appearance during the summer season.
Astilbes are not prone to insect pests or disease. They attract butterflies and are NOT eaten by deer. For vigor, they should be lifted and divided during autumn every 2 to 3 years.
They can be propagated by division during autumn, seed, or runners if produced.
Root cuttings are also used.
