Mammoth dill, also known as Long Island Mammoth dill, gets its name from its size: this variety can grow up to 3 to 5—and occasionally up to 6—feet with a 2-foot spread. Not surprisingly, Mammoth produces giant flowers with seed umbels reaching up to 15 to 18 inches across. This spectacular dill plant variety attracts many beneficial insects and hummingbirds.

  • Giant flowers and umbels attract beneficial birds and insects
