The plants that come back. Herbaceous perennials rise from the crown each spring, flower through the warm months, and retreat to the ground in winter, returning larger the year after. They are the flowering heart of the border, the long-term investment that repays a gardener season after season.
Tulbaghia violacea, the plant gardeners know as society garlic, is a clump-forming perennial from the summer-dry grasslands of southern Africa, ranging from the Little Karoo through the Eastern Cape to KwaZulu-Natal. The genus honors Ryk Tulbagh, the eighteenth-century Dutch governor of the Cape of Good Hope, while the species name violacea simply means violet, for the color of the flowers. The common name is a small joke: the leaves carry a clear garlic scent, but a gentler, more sociable one than true garlic, said to be polite enough for company.

'Homestead Purple' is one of the great garden discoveries of the modern South, a trailing perennial verbena found not in a breeding plot but by the side of a Georgia road. In the early 1990s the University of Georgia horticulturists Michael Dirr and Allan Armitage drove past a sheet of royal-purple bloom at an old homestead, turned around, and gathered cuttings from a plant the owner said had simply grown there for years. That roadside find became one of the most popular perennials in American gardens, and the botanists gave the plant the name of the place it was found.
A native violet grown as much for the leaf as the flower. Viola walteri, Walter's violet, belongs to the violet family, Violaceae, and honors the British-born botanist Thomas Walter, whose Flora Caroliniana of 1788 was the first flora of the American Southeast. The prostrate blue violet ranges in the wild from Texas east to Florida and north to Virginia and Ohio, threading the floors of moist deciduous woodlands and shaded rocky ledges.
