'Sister Theresa' Astilbe glows with thick, cotton candy-colored plumes that sway softly in the breeze. Mounds of finely-cut, green foliage remain true throughout the season, providing a graceful backdrop for later-blooming flowers. Lovely in rock gardens and when planted in drifts. Prefers moist soil. (Astilbe arendsii)

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
About Astilbes: Easy to grow, tough and hardy, Astilbes are now a mainstay in all good perennial gardens. In fact, American gardeners are in the midst of a passionate love affair with Astilbes. Native to the far east, these beautiful plants and their hybrids have revolutionized the perennial possibilities of moist, shaded American gardens. They are companions of ferns and our favorite annuals, impatiens--one of the few flowers that make big color in full or partial shade.
