The development of tissue culture propagation or multiplication has had dramatic effects on ornamental plant breeding. Now crosses can be made without concern for uniformity of seed production. A single improved plant can be increased to hundreds of thousands using tissue culture.
Since gardeners prefer to buy started plants rather than seeds for ornamental plants, it does not matter whether the plant was grown from seed or tissue culture. This has reduced the amount of time needed to develop new varieties. The plant patent process can be used to maintain the originator’s control of a new variety.
So I don’t pay any attention to how a new plant variety was developed. I grow it based solely on how it performs in my garden. I still grow a few heirloom varieties because they have unique qualities that I appreciate.
