If you are actively trying to come across other varieties I have no doubt you will be successful. Before you know it you will be growing your own from seed and be completely addicted to them. Everyone of them have their own personalities and it is so much fun adding to the collection. My husband brought me home a white one day when he was in the dog house and I have been a hopeless addict ever since.
We have a great support group here to help out with that though!
