These perennials usually remain in the 1 to 2 feet high range under most conditions. They are still low enough for the front of perennial border, garden, and landscape and some of the rhizomatous species will make low to medium height groundcovers. Their tidy habits also lend them to use as fillers and spillers for container specimens and in combinations for small to medium sized containers. Growing conditons and how well a plant is established may affect it's ultimate size.
According to Dr. Allen's Edible Plants of the Gulf South, Wild Chervil or Honewort is an easy to grow, native, tuberous rooted perennial whose leaves, stems, and flowers are useful fresh in salads or can be cooked as a green, the tuberous roots can be used as a starch, and the seeds can be used as a spice. Grow it as a loose groundcover in shade to partial shade in a moist, but not soggy soil, preferably rich in organic matter. A host for the Eastern Black Swallowtail butterfly. Item# 10219.
