The seed company also includes wheat celosia in its Heirlooms catalog. There is a new celosia on the market these days. This multiflora celosia produces numerous but smaller cockscomb flowers. Look for plants this spring. Plant them in full sun at home.
Seed is available from catalogs.
One plant that I have enjoyed since I first saw it in a nursery about four years ago is painted tongue. At first glance, you may think painted tongue is an exotic petunia. Touch the plant. It's sticky, too. But painted tongue is more upright, with short, multiple branches.
