Chocolate Shogun is a Japanese astilbe introduction bred by Nagasaki Teruhisa in 2010. It is a Thunbergii species with larger leaves and less conspicuous flowers. But the foliage is what this variety is famous for – the divided leaves are dark purple to almost chocolate brown and contrast beautifully with other green-leaved plants around, adding drama to any landscape. In mid June rise about 50 cm tall stems with several loose tiers of pale pink flowers. Patent No. PP26430 was granted in 2016.
Grow astilbe in humus-rich soil. If planted in boggy or regularly watered bed they can sit in full sun, too, otherwise choose a semi-shaded or shaded location. They are water loving plants and require a good dose of nutrients to look their best. They will not grow in chalky or clay soil that dries out in summer.
For best results divide the clumps every 3-4 years removing old and dead rhizomes in early spring. Also in the spring remove old leaves and last year’s flowers. If grown in poor soil you may need to cut back the entire plant after flowering to get rid of spent stems and tired foliage in order to encourage growth of new leaves. A dose of a liquid fertilizer is recommended. Fully hardy to about -34°C (USDA zone 4).
