- Red and white flower parts combine to form vibrant rosy-red plumes on upright, red stems
- Blooms in mid to late summer
- New foliage has red tinting, maturing to dark green
- The leaves are larger than most others in the Simplicifolia group
A member of Astilbe simplicifolia (Astilbe). A species characterized by glossy, mid-green leaves which are lobed, not divided. Plants form compact mounds that look good even without flowers. Open, airy panicles of star-like flowers are followed by ornamental seed heads which provide a few additional months of interest. Slower to establish than A. arendsii, requiring about 3 years to reach maturity.
Origin: Not Native to North America

Astilbes are long-lived perennials that are most comfortable when grown in rich soil and light shade to filtered sun. They will grow in full shade, but will not bloom as prolifically there.
Though they are easy to grow, Astilbes have one critical requirement--lots of water. Plants must have consistently moist soil; dryness leads to a quick demise, especially in sun. Increase watering as the foliage emerges and the plumes mature. If the soil dries out, the leaves will develop brown, crispy margins and will begin to drop.
Fertilize Astilbes in late spring before flowering starts. Wait to cut back the old foliage until spring; it will help protect the plant from winter damage. In the spring, if the crown has risen above soil level, gently press it back into the ground and apply some organic matter around the plant. Plants should be divided in early spring every 3-4 years to maintain vigor.
The word "Astilbe" probably means "without showiness" in Greek, referring to the original flowers from China. Today's hybrids are definitely showy!
