This description is for Agastache: The Agastache, or Hyssop, is a wonderful family of flowers that will attract hummingbirds to sample their sweet nectar. Not only do they sport wonderfully delicate spires of various coloured blooms, but they also emit a delightful scent. Not only will hummingbirds visit, but butterflies and bees as well, making them a wonderful choice if you like to watch wildlife. Most are susceptible to frosts, so will need protecting or moving indoors during the colder winter months.
