Other Names: Bigleaf Aster, Big Leaf Aster, Aster macrophyllus
Description:
A profusion of airy white or violet flowers, over a mound of large, heart-shaped green leaves; thrives in shade and tolerates dry conditions; water the root zone instead of from the top to reduce fungal disease; water regularly to encourage more blooms
Ornamental Features
Large-leaved Aster has masses of beautiful white flat-top daisy flowers with violet overtones and gold eyes at the ends of the stems from early summer to mid fall, which are most effective when planted in groupings. Its large serrated heart-shaped leaves remain light green in color throughout the season.
Landscape Attributes
Large-leaved Aster is an herbaceous perennial with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.
This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;
Large-leaved Aster is recommended for the following landscape applications;
Planting & Growing
Large-leaved Aster will grow to be about 3 feet tall at maturity, with a spread of 3 feet. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 4 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
This plant does best in partial shade to shade. It is very adaptable to both dry and moist locations, and should do just fine under typical garden conditions. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. This plant should not require much in the way of fertilizing once established, although it may appreciate a shot of general-purpose fertilizer from time to time early in the growing season. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is native to parts of North America. It can be propagated by division.
Large-leaved Aster is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
