Astilbe arendsii ‘Red Cattleya’

Red Cattleya’ is almost identical to the popular ‘Cattleya’ except the plumes are dark red instead of orchid pink. It is a tall cultivar, which features large panicles of dark red flowers on upright stems (to 3.5′ tall). Typically forms a foliage mound to 12-15″ high. Fern-like leaves emerge tinged with red but mature to dark green. This variety was named for the popular orchid genus.

This is an excellent border plant and when used as a mass planting, with showy plume like flowers. Mass or group in shade gardens, woodland gardens and shaded areas of border fronts or cottage gardens. ‘Red Cattleya’ is also very nice as a ground cover or edging plant for shady areas. Astilbes are always terrific on ponds or stream banks, since they love shady moist sites.

General Information +

Botanical: Astilbe arendsii 'Red Cattleya'

Common: Astilbe (False Spirea)

Family: Saxifragaceae

General Characteristics: Astilbes are a mainstay of shade and woodland gardens. They are clump-forming perennials which feature graceful, fern-like mounds of mostly basal, 2-3 ternately compound leaves, usually with sharply-toothed leaflets, and tiny flowers densely packed into erect to arching, plume-like flower panicles rising above the foliage on slender, upright stems. One of the arendsii hybrids. The arendsii hybrids are a large group of hybrids involving crosses between A. chinensis, A. japonica, A. thunbergii and A. astilboides and are named after German nurseryman George Arends (1862-1952). Because of the different and sometimes complex parentage of the plants lumped under this hybrid grouping, arendsii hybrids can vary considerably as to plant size, inflorescence shape, leaf color/shape and bloom period. Generally, however, they are early which grow 2.5 to 3 feet tall with ovate to lance-shaped leaflets.

Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems. Unlike the Chinese astilbes (A. chinensis cultivars), the arendsii hybrids have little if any drought tolerance. Foliage decline (leaves brown up), sometimes with significant dieback, will often occur in hot summers and/or periods of drought if soils are not kept uniformly moist.

Planting Instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Easily grown in average, medium, well-drained soils in part shade to full shade. Prefers moist, humusy, organically rich soils. Soils must not be allowed to dry out. If regularly watered, foliage will usually remain attractive throughout the growing season. A summer compost mulch helps retain soil moisture. Removing faded flower stalks will not prolong bloom but may improve plant appearance, particularly if a ground cover look is desired. On the other hand, many gardeners leave the flower stalks in place after bloom because of the continuing ornamental interest of the dried seed heads. Divide clumps when overcrowding occurs (every 3-4 years).
