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. As a border plant they are excellent and easy to grow.
Some varieties have single petals, while others have showy semi-double or double petals.
This very old-fashioned flower has been around forever, it seems. An interesting side note about hollyhocks. Research indicates that hollyhocks were often used by people in ancient times for medicinal purposes. If you want to attract BOTH hummers and butterflies, you should definitely consider the endearing hollyhock for one of your tall border plants. Cleome blooms with many open, fluffy clusters having pink or white blossoms with protruding stamens.
