Product Details

When a hint of fall is in the air and our shade gardens look tired, we often look to nature for inspiration. Masses of Blue Wood Asters covered in light blue Daisy-like flowers weaving through other wildflowers at woodland edges is one sight well worth transporting home. In nature, as with most seed-grown plants, the straight species Symphyotrichum cordifolium flower color is variable, ranging from intense blue to paler tones to nearly white. An adaptable species, with sufficient moisture, it grows in full sun, but is especially valuable in shade, where it vigorously naturalizes. Its heart-shaped basal leaves form a handsome ground cover, mingling with other woodland plants.

Symphyotrichum is primarily native to North America, with a few species occurring in South America and Eurasia. This large genus within the Aster family includes over 90 species of mostly perennial plants that are hardy in Zones 3 through 8. Profuse, Daisy-like flowers bloom in late summer to fall, presenting a palette of colors, typically in shades of blue, purple, white, and pink. These blooms play a crucial role in supporting pollinators—such as bees and butterflies—when other blooms are diminishing. Plants prefer full sun to partial shade and thrive in well-drained soil, although they are adaptable to a variety of moisture levels and soil types. Symphyotrichums create a naturalistic planting and are a vibrant addition to perennial borders, providing both late-season color and an essential food source for wildlife.

HOW PLANTS ARE SHIPPED

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.

WHEN WE SHIP

We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the expected time of delivery.

Until recently plants now classified as Symphyotrichum and Eurybia were classified with Asters. However, even though the horticultural classification has changed for some of the plants we offer, they all share the same growing instructions.

Grow in full sun (or partial shade in the South) in moist but well-drained soil (A. amellus tolerates drought). S. novae-angliae varieties are susceptible to powdery mildew in dry soil. They also require division every year or two to remain vigorous. S. novae-angliae varieties may require staking; if you prefer, you can pinch them back once or twice (by 1/3–1/2) before the end of June (July in the South and the Southwest) to keep them compact. In the South, A. X frikartii 'Monch' may stop blooming by midsummer; shear it back by half, and it will bloom again through the better part of fall.
