Welcome, plotstoeat, if no-one has said it yet. I always start a few off in pots, but since I've been growing sunflowers for years I get self-set seedlings every year - I just transplant to where I want them. Once the heads are ripe I distribute them around my garden, hang some from trees, last year I wedged one in the fork of an apple tree which was very successful with the squirrels..... >:(
