As Hetty says, the vast majority of our seedlings will be cross-pollinated rather than true hybrids and thus each and every one of them will be unlike any other Plumeria. The plants and the flowers may be similar to others, but their individual DNA will be different. That's why she was able to name hers (they are basically her one-of-a-kind property) and why she took the best to present to the Plumeria Society of America for recognition.
