Q.Fall care of verbena
My purple verbenas, about 18″ high are still blooming vibrantly on Nov. 9.
I do not know the variety, but I am assuming they are perennials.
We had a light frost, but it did not affect them. I am assuming I should cut these back after a hard frost and hope for the best. Should I feed them lightly in the fall or wait until spring?
Thank you, Nancy

The big question here is whether you have an annual or perennial verbena. Most sold at local nurseries are annuals. You can collect seed or take cuttings this fall. If you didn't steadily deadhead spent blooms, verbena may self-sow. New stems and leaves will emerge next spring if you have a perennial variety. Cut down the stems either this fall or early next spring. This article explains: https://www.gardeningknowhow.com/ornamental/flowers/verbena/annual-perennial-verbena-varieties.htm
Try looking at google images of verbena to ID your variety. Many annual verbena are hybrids and will not come true from seed.
