Culture
Best grown in organically rich, humusy, evenly moist, well-drained soils in full sun to part shade. Soils must not be allowed to dry out. Plants are best sited in part shade locations with protection from wind. Foliage tends to burn in hot, dry, sunny summer conditions. Plants do not perform well in the deep South (south of USDA Zone 7). Avoid wet, poorly drained soils, particularly in winter. Plants appreciate a winter mulch in cold winter climates. Plants may be slow to establish, but will naturalize well by spreading rhizomes in optimum growing conditions. Propagate by root cuttings in winter (perhaps most effective) or by division in spring.
Noteworthy Characteristics
Anemone × hybrida, commonly called windflower or Japanese anemone, is a hybrid category which includes a large number of hybrid pink or white flowered cultivars that bloom from late summer into fall (August - October). These cultivars vary somewhat in character but generally are erect, clump-forming, fibrous-rooted, woody-based perennials which typically grow to 2-3' (infrequently to 4') tall on stems clad with oval palmate toothed leaves.
Genus name is often said to be derived from the Greek word anemos meaning wind.
'Honorine Jobert' is a vigorous, fibrous-rooted, mounding, compact Japanese anemone hybrid cultivar which typically grows to 3-4' tall and spreads by creeping rhizomes. Single flowers (2-3" diameter) with 6-9 overlapping white petaloid sepals and yellow center stamens appear on long, wiry-but-graceful, branching stems over an attractive foliage mound of trifoliate dark green leaves. Lengthy August to September bloom period. Japanese anemone cultivars are commonly sold as Anemone x hybrida or Anemone japonica. 'Honorine Jobert' is an old garden hybrid discovered in Verdun, France in 1858. Synonymous with A. x hybrida 'Alba'.
Problems
Watch for leaf spot, powdery mildew, downy mildew, rust and leaf/stem smut. Caterpillars, slugs and nematodes may be troublesome. Black blister beetles and Japanese beetles can defoliate plant foliage in some areas. Taller plants may need some staking or other support.
Uses
Excellent fall bloomer. Perennial borders, cottage gardens, woodland gardens. Effective when massed. Attractive with hostas and astilbes.
