Also know, do sunflowers come back year after year?

One may also ask, do sunflowers grow back after cutting? When your sunflowers tend to grow too tall for your liking, giving them a trim encourages shorter, bushier growth. After blooming, sunflowers start to develop a ragged appearance, so it's best to cut them down completely. Perennial varieties can grow back and flower again next year.
