Woodbine can also spread quickly by self-seeding and root suckers, but it is not considered invasive. Woodbine needs moist but well-drained soil.
Grow this native clematis on a trellis or arbor, or allow it to climb along a fence. Woodbine blooms on the current year’s growth, so you can prune it in late fall after flowering or in late winter or early spring before the plants break dormancy.

Once established, these plants are tolerant of some drought. Rabbits will nibble on young plants but typically don’t bother larger, more mature plants. If you have room in your landscape for some zinnias, these beautiful flowers won’t disappoint.
Frequently Asked Questions
It’s already fall! Am I too late to start fall flowers?
Buying fall-blooming plants from your local garden center is the best way to incorporate some quick color into your garden. Check out readily available and easy-to-grow plants such as fall-blooming chrysanthemums, snapdragons, and pansies. These plants will give you quick access to some fall colors. Create a colorful seasonal planter arrangement, or plant them directly into your garden and enjoy them until the first frost.
What should I do after my plants are killed by frost?
If you are growing seasonal annuals, remove the entire dead plant after frost and compost it. If the plants show obvious signs of pests or diseases, don’t put them in your compost. Dispose of diseased plant materials in a location that won’t risk infecting your garden in the future. Herbaceous perennials can be left standing through the winter and pruned back in late winter before new spring growth appears.
Will fall-blooming perennials overwinter in containers and raised beds?
Depending on where you live and how cold your winters get, you may be able to overwinter perennials in containers and raised beds. In cold climates, you will probably have the best success overwintering your plants in the ground and giving them an extra layer of mulch to help protect them from the cold. In milder climates, some perennials will overwinter just fine in large containers and raised beds. You can still add a layer of mulch to protect them, and with smaller containers, you can keep them in a cool, dark, protected location during the winter, such as an unheated garage, and bring them out again the following spring.
Final Thoughts
Don’t give up on your garden by the end of summer. Fall is a fabulous season for planting and enjoying abundant, fresh, and beautiful autumn colors. Some plants will bloom non-stop from summer into fall, while others will suddenly burst into full bloom as the weather cools. You can start some plants from seed in the spring or summer for fall blooms, start perennial seeds in the fall for next year’s bloom, or buy young nursery-grown plants to transfer immediately into your home garden. Whichever method you choose, you will have plenty of options to brighten your landscape this fall!
