Growing wedding flowers from seed
I'm getting married next summer, August 16th. I've always wanted to grow at least some of the flowers for my wedding myself, both for sentimental and financial reasons. However, I'm currently working in France and won't be back in the U.S. until the end of May.
I wouldn't call myself a good or an experienced gardener, but I've always been a compulsive dabbler in plants and dirt. I'm interested in easy to grow plants that can be direct sown or sown outdoors in pots in late May for an August bloom.
Some I'm considering are zinnias, orlaya lace flower, cornflowers, snapdragons, love lies bleeding amaranth, dill, nigella and feverfew or chamomile.
Any advice or suggestions? Of the plants I listed, any that wouldn't perform well under the circumstances I described? I'm planning to buy some dahlia tubers, too, but I don't know if the end of May is too late to plant them, especially since I read that they're a bit heat sensitive.
I'd love to hear any other plant suggestions, and everything you can tell me about the needs of the ones I listed and their potential as cut flowers in August.
