September highlights
Angel’s Trumpet
The trumpet shape and strong, sweet aroma of these supersized, pendulous blooms inspire the common name of this genus. Among the most toxic of ornamental plants, Brugmansia species are known only in cultivation and are presumed extinct in the wild.

Harlequin Glory-Bower
Native to Eastern China and Japan, this deciduous shrub boasts fragrant star-shaped flowers in mid-summer and dark blue berries in fall. It is sometimes called the “peanut butter tree,” in reference to the scent emitted from crushed leaves.

White Wood Aster
This white-flowered aster grows well in the shade. Here you can see how aster disc florets fade from yellow to red as they age. Bees visit the yellow-centered blooms, which contain more pollen and have not yet been pollinated, but the darker florets still help draw pollinators from afar.

Swamp Milkweed
Milkweeds are host plants to monarch butterflies, which can be seen flitting about them in the summer. The seedpods, which dry out during fall, are also filled with silky filaments that help carry the seeds far from the mother plant when the wind catches them.
