Lantana
Lantana loves full sun. It’s deer resistant and comes in different forms: mounding, tall, small (for containers), as well as trailing and weeping forms. It attracts lots of pollinators, especially butterflies, and comes in many different colors
Vinca
Vinca is a sun lover. Typically produces a periwinkle-like flower that comes in many colors. Deer hate it. It is drought and heat tolerant.
Mandevilla
Very colorful and showy. It is tropical like hibiscus and bird of paradise. It is one of those house plants that bloom brighter when you keep them outside. But take care where you place it. Mandevilla is NOT DEER RESISTANT.
Petunias and Verbena
These are trailing plants that will spill gracefully over the edge of a container. New cultivars are more compact and show off many more blossoms. The more sun they get, the more profusely they bloom.
