Title: Tall perennials for a sunny North Carolina border
Answered by: Guy Thompson
I didn't find any truly evergreen native plants that seemed appropriate for your requirements, but there are many that are tall with a relatively small footprint. The first five do bloom in autumn, perhaps even into November and December, giving you some late color: Gentianopsis crinita (Greater fringed gentian), Liatris aspera (Tall blazing star), Liatris spicata (Dense blazing star), Phlox paniculata (Fall phlox), and a Mexican native Salvia elegans (Pineapple sage). These additional species should also do well in your area. Ipomopsis rubra (Standing cypress), Monarda fistulosa (Wild bergamot), Rudbeckia hirta (Black-eyed susan), Penstemon canescens (Eastern gray beardtongue), Penstemon australis (Eustis lake beardtongue),Asclepias tuberosa (Butterflyweed), Lobelia cardinalis (Cardinal flower), Penstemon digitalis (Mississippi penstemon), and Physostegia virginiana (Fall obedient plant). The Fall obedient plant, in particular, tends to spread quickly, but the new shoots can be easily pulled up.
You can find more possible species at the North Carolina Native Plant Society web site. A list of native plant suppliers in your area is found at the Lady Bird Johnson Wildflower Center web site.
