How to Grow Boltonia

Autumn Bouquets

Fall is a wonderful time to savor the beauty of the natural world before the garden hibernates during winter. A great cutting garden offers stems for snipping from spring through the first frost. Call on boltonia to anchor the late summer and fall cut-flower collection. Additional late-season cutting flowers include sedum, goldenrod, purple coneflower, black-eyed Susan, New England aster, perennial sunflower, and Japanese anemone. Add small twigs with colorful leaves for a texture surprise in your fall bouquet.

Plant this tall perennial at the back of a flower border, in an easy-care native plant or meadow garden, or among shrubs for a burst of late-season flower color. This tall, showy North American native is also a food and habitat source for wildlife.

Boltonia Care Must-Knows

Boltonia tolerates a wide range of soil types, including moderately dry ones. For best results, plant this perennial in full sun and well-drained soil with medium moisture. Plants grown in part shade and moist, rich soil tend to develop weak stems and need staking as they mature.

Plant boltonia in spring or early summer and water it regularly during the first growing season to encourage young plants to develop a strong root system. Although this late-season showstopper is typically started from nursery-grown transplants, it's also easy to start from seed planted directly in the garden in spring.

Promote dense, compact growth by pinching or cutting back stems in late spring or early summer by one-third their length. The plant will push out new, branched growth and be less likely to require staking when blooming in fall. Boltonia spreads slowly via creeping rhizomes. Divide it as necessary in early spring as soon as the shoots emerge from the soil.

Here's how to divide perennials.

More Varieties of Boltonia

'Snowbank' boltonia

Boltonia asteroides 'Snowbank' is a popular variety because it is slightly shorter than the species, growing 3-4 feet tall with full-size white daisy blooms.

Plant Boltonia With

Bluestar
Amsonia is one of those plants that will make people stop in their tracks and ask what it is. At its peak in mid- to late spring, amsonia is adorned by stunning clusters of powder blue flowers. The show doesn't stop there, however. Its mound of foliage remains attractive all summer long, and as fall approaches, it turns a lovely golden hue. Although the seed pods that develop are attractive, remove them before they mature to prevent self-seeding.
Joe Pye weed
Joe Pye weed is a showstopper of a prairie native, producing huge, puffy flower heads in late summer. It prefers moist soils, but with its extensive root system, it also tolerates drought well. It is a large plant, growing 4 to 6 feet tall.Closely related, hardy ageratum is a spreading plant that grows to only 2 feet tall. Another relative, white snakeroot, reaches 4 to 5 feet tall. All are great for naturalistic or cottage plantings and for attracting butterflies.
Miscanthus
Miscanthus is one of the most prized of ornamental grasses, and one particular cultivar, 'Morning Light', sums up much of its appeal: This grass is stunning when backlit by the sun, either rising or setting.Statuesque miscanthus makes dense clumps of arching grassy foliage in an assortment of widths, decoration, and fineness, according to variety. Erect, dramatic plumes of flower spikelets rise among the leaves or well above them and last beautifully through the winter. Site miscanthus with good drainage and plenty of space in sun or light shade.
