If you want hummingbirds in your yard, you only need two plants (but please plant more than 2): 'Jacob Cline' Bee Balm and Cardinal Flower. In summer, 'Jacob Cline' will send up a mass of red blooms that look equally amazing in your yard as they do to the hummingbirds. 
 
Members of the Monarda didyma family support at least 3 specialized bees, butterflies, and, of course, hummingbirds. They are larval host to up to 12 species of moths and butterflies, including the Orange Mint moth, the Hermit Sphinx, and the Raspberry Pyrausta.
 
As a member of the mint family , 'Jacob Cline' bee balm spreads well by underground stolons. If you are limited on space, it is very easy to pluck some out and share it with a friend.
