Therefore, you should include some red and possibly white delphiniums to make a showy contrast with the bright blue ones. Keep in mind that it s the nectar that hummingbirds really need. But having color choices that blend well is also important for a great looking border. Delphiniums give you some lovely color blending choices. Their colors range from soft white to shades of pale or deep pinks, all with speckled throats.
Foxgloves are some of the easiest of tall flowering plants to grow as border plants.
Again, they are a favorite of hummingbirds because of their tube-shaped blossoms with rich nectar. Plant foxgloves about 1 foot apart, or mass them at the back of your border against a fence or bare wall, interspersing them with your delphiniums. Their colors will blend beautifully with our other selected flowers as they come into full bloom. Both foxgloves and delphiniums make excellent cutting flowers for fresh arrangements in your home. Foxgloves are either a perennial or a biennial, and therefore may need to be replanted as the need arises.
