Q.Full Shade Hummingbird Plants, S. Fl., Zone 9. All Year Blooming, At Least Fall Into Winter & Winter Into Spring 26′ X 2′
raised bed. Perhaps I wasn’t clear, I’m looking for perennials that will bloom all year long. At least some that will bloom into early Winter or some that will start blooming late Winter. Also, can I cut some perennial back to the ground, making room for the blooms of other perennials & when they have finished cut them back to the ground for the next perennial blooms, thus creating a cycle?
