(Climbing Carolina aster)
This perennial vine sends out abundant pale purple to lavender flowers beginning in late October. It grows to 4 to 5 feet tall, and frost does not seem to impede the blooms. It can attract bees and butterflies well into November.
To get the best flower display, give climbing aster as much sun as possible. It should also have something to lean on, like a fence, a trellis, or an ornamental shrub. Don't prune it over the winter, no matter how dead it may look. It’s better to wait to tidy up things after the new growth appears in spring.
