Astilbe Radius, Astilbe 'Radius', is an outstanding new hybrid that starts showing off in the spring when the foliage emerges dark red, and then matures to dark green. Astilbe 'Radius' blooms profusely in midsummer when the dark red flowers buds open to deep rose-red plumes that butterflies love. Radius is perfect for 'lifting' shady areas. Deadheading will not increase blooms, so leave the dried seed heads to provide late season interest. Cut back hard in spring. Slightly fragrant and makes a great cut flower. 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 the sun. 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.
