Cultivation
While the white wood aster does not compare in popularity to the other cultivated asters, such as the New England aster, it does have its niche, especially in North American native gardens. The plant flowers earlier than many other asters, does not require any staking to support it and flowers well in shade. It is attractive to gardeners due to its showy white flowers that emerge in mid to late summer, its prostate habit, as well as its hardiness and the minimal maintenance it requires. It has little problem with both disease and insects. They do require partial shade, however, and they perform best when given about 4 hours of sunlight. The plants can be cut to 20 cm (8 inches) in the spring in order to delay flowering and increase the number of branches. It is marginally hardy in USDA zone 3, and fully hardy from zones 4 to 8. It is commonly available in North American nurseries and several cultivars have been selected, including:
- 'Fiesta', which has leaves streaked with white, giving the effect of confetti, and flowers that are light lavender. The selection was made in Waseca, Minnesota.
- 'Raiche Form', which has white flowers that are larger than usual and darker, thin, sinewy stems. The cultivar was found by Roger Raiche.
- 'Snow Heron', which has white flowers and dark green leaves splotched and streaked with white. The cultivar was selected from a chance seedling grown at the Heronswood Nursery in Washington.
