Ruby-Throats are the only hummingbird species that regularly calls this area home for the summer breeding and nesting season.
The Three Keys Flowers Ruby-Throated Hummingbirds Need
Studies have shown that the Ruby-Throated moves northward as three key flowers come into bloom. Those plants are Red Buckeye (Aesculus pavia), Clove Currant (Ribes odoratum) and Wild Columbine (Aquilegia canadensis). Now we know what to plant for those early arriving Ruby-Throats.
