The genus Astilbe comprises about 18 species of perennial, rhizomatous plants in the saxifrage family (Saxifragaceae), native primarily to East Asia (China, Japan, Korea, the Himalayas) and partly to North America. The first specimens were introduced to Europe in the 19th century, for example from Japan by Dutch botanist Philipp Franz von Siebold (1796–1866). Ever heard of him? A rare and beautiful summer-flowering magnolia, Magnolia sieboldii, was named in his honour. In Europe, Astilbe — known as false spiraea — quickly gained popularity for its elegant, feathery flower plumes and decorative foliage. A significant breakthrough in breeding came thanks to German horticulturist Georg Adalbert Arends (1863–1952), who in the early 20th century developed numerous hybrids known as Astilbe × arendsii. This line, created primarily by crossing A. japonica, A. thunbergii, and A. chinensis, brought a revolution to garden planting — offering a broader colour palette, longer flowering times, and greater adaptability to various conditions.
Astilbe x arendsii is a popular, low-maintenance perennial with charming, plume-like flowers in summer. The offer several colours – creamy white, pink or red. Leaves are dark green and glossy forming a dense clump.
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.

In their natural habitat, astilbes thrive in mountain ravines and damp forests, where they appreciate shade and moist soil. Thanks to their tolerance for both shade and moisture, they have become popular perennials for planting around ponds and in woodland gardens. They are not difficult to grow as long as they have proper conditions: rich, moisture-retentive soil and a preference for partial shade over full sun. However, given regular watering or a naturally damp site, they will also perform well in full sun. Good fertilization enhances both the size and quality of the blooms. Avoid overly alkaline soils and compacted clays that dry out in summer — they are not suitable. For optimal performance, divide and rejuvenate clumps every four years, removing old and dying rhizomes. Do this in early spring before new growth starts. Old foliage and flower stalks should also be cut back in early spring. Fully hardy to approximately –34 °C (USDA zone 4). Perfect for large planters, too, where it will require more frequent watering and feeding.
