Agastache foeniculum by squamatologist
One of the herbs that I bought at Russell Gardens Wholesale was Agastache foeniculum – Giant Hyssop or Anise Hyssop ‘Blue Fortune’. Though I bought the plant, it is easy to grow it from seed. And if you have friends who have Agastache, I feel certain that they will be happy to give you some plants since it spreads easily when planted where it is happy.
There are about 30 species of Agastache and most are native to North America. The Agastache I have grows in Temperature hardiness zones from 4 to 9, is over 4 feet tall and blooms from late June through September. I bought Agastache, an aromatic perennial, not so much for its flowers but because it is a rich source of nectar so that it attracts bees and butterflies and is supposed to attract hummingbirds; though I think the flowers make a nice addition to an indoor bouquet.
