General Information +

Botanical: Astilbe japonica 'Bonn'

Common: Astilbe (False Spirea)

Family: Saxifragaceae

General Characteristics: Easy to grow in average soil kept evenly moist. Provide mulch and extra water in dry times. Fertilize each spring for best display. Excellent cut flowers. Excellent in beds and borders, or moist woodland settings. Astilbes are mainstays of shade and woodland gardens. Site lacy astilbes near full foliage plants like hostas for an appealing contrast in forms. 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.

Planting/Care Instructions +

Pests or Diseases: Deer resistant.

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).
