Culture

Best grown in moist, fertile, organically rich soils in full sun to part shade. Foliage decline can occur rapidly if soils are permitted to dry out. With consistent moisture, it performs well in full sun in the northern portions of its growing range. It prefers part shade in the southern part of its growing range. 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, flower stalks on female plants may be left in place to enjoy the continuing ornamental effect of the dried seed plumes. Plants can be slow to establish. Plants may struggle in the hot and humid conditions of the deep South and are not recommended for gardens south of USDA Zone 7.

Noteworthy Characteristics

‘Zweiweltenkind’ (sometimes described in translation as 'Child of Two Worlds') is a compact variety of goat’s beard that typically grows to only 30" tall. Fern-like, pinnately compound, dark green leaves on sturdy stems form an attractive astilbe-like foliage mound. Tiny, creamy white flowers in showy, elongated, terminal and axillary panicles (each to 7” long) rise well above the foliage mound in late spring (May-June in St. Louis) to a height of 20-30” tall. As the specific epithet suggests, these plants are dioecious (separate male and female plants). Male plants may have larger and slightly showier flowers, but female plants have attractive drooping seed plumes in fall.

Problems

No serious insect or disease problems. Some susceptibility to leaf spot.

Garden Uses

Ground cover or edging. Partly shaded areas of rock gardens, border fronts, open woodland gardens or shade gardens. Mass plantings are excellent in flower.
