| Description | An Astilbe with white flowers |
|---|---|
| Pronunciation | (ah-STIL-bee) |
| Plant Type | All Plants, Perennials Hardy |
| Hardiness Zone | 4-8 |
| Sunlight | Prefers semi-shaded sites, will tolerate more light if the soil is kept moist. |
| Moisture | Needs moist soil. Plants growing in dry conditions will be small, few blooms and tend to dry up during the hotter days in the summer |
| Soil & Site | rich, humusy moist well-drained soils |
| Flowers | branching panicles of white flowers |
| Leaves | dark green, ternately compound and the leaflets are coarsely serrated, dissected foliage is an attractive feature of the plant |
| Maintenance | Division of the clumps every 2-3 years will help to maintain the vigor of the plant. Astillbe are heavy feeders and need to be fertilized every year in the spring and also in the early fall. Some of my Astilbe tend to heave in the winter. In the spring I cover the exposed roots with soil, mulch or dug them in. Be careful since many Astilbe are easily pulled out of the soil |
| Propagation | division |
| Misc Facts | George Arends of Germany was one of the first to create new varieties of Astilbe (x ardensii) which lead to the plants popularity |
| Author's Notes | I have a group of Astilbe in a 1/2 to 3/4 day full sun for over 10 years and they are a show stoppers when blooming. To achieve this they are growing in a bed that is raised a few inches and the soil is naturally constantly wet. The main factors to get maximum performance are proper soil moisture, division and fertilizing. |
