Boltonia

Snowbank boltonia, although usually strong enough to support itself, may also benefit from cutting back now if it's growing in too much shade or in soil too rich.

It will take time to fully understand the long-term impacts these sprawling infernos will have on everything from the threatened Apache trout (Oncorhynchus apache) to the endangered Houston toad (Bufo houstonensis), and what the chaotic flooding throughout the heart of the country will mean for species like the threatened decurrent false aster (Boltonia decurrens) to the endangered interior least tern (Sterna antillarum).

Another time I grew and tended many late blooming perennials all summer: cleome, Mexican sunflower, zinnias, goldenrod, boltonia, and asters.

Site 5 (see Table 1), 2.3 miles north of Bath on the W side of IL78, had 12 plants of the federally listed Boltonia decurrens (Torr.

In her southeastern Pennsylvania garden, Nancy Ondra, author of the book Fallscaping, relies on long-blooming perennials like Shasta Daisy (Leucanthemum), Coreopsis (Coreopsis lanceolata) and perennial sages (e.g., Sage officinalis) that start flowering in summer and keep going into the fall and those like Asters (Asteraceae), Boltonias (Boltonia asteroides) and Joe-Pye weeds (Eupatorium purpurea) that rebloom in fall if you cut them back after their first round of summer flowers.

I took classes at the New England Wild Flower Society's native plant center, and grew beautiful native flowering plants such as butterfly weed, liatris, coneflower, boltonia, rose mallow, virginia rose, rudbeckia, New England aster, perennial sunflowers (helianthus) and native grasses, such as switch grass.

An experimental investigation, using stomatal conductance and fluorescence, of the flood sensitivity of Boltonia decurrens and its competitors.

You don't need to know a Brachyscome from a Boltonia (fyi: both are daisies) to enjoy a garden tour.
