Hello all,
Well, my list is really short: Zinnias!
Growing and breeding zinnias is a hobby of mine. There are dozens of different varieties of zinnias, so the number of different crosses you can make with them is literally astronomical. This is one of my home-hybridized zinnias. I make hybrids between hybrids, somewhat willy nilly. I get some unusual results.
Botanically, any part of a plant that is capable of producing a seed is a "flower". So each petal of a zinnia bloom is botanically a "flower". (Each petal can produce a seed.) In that breeder zinnia the petals are tubular and they are somewhat reminiscent of being individual "flowers".
