You are right, many of the newly discovered species may prove to be varients of old ones. Ever once in a while there is a really beautifully and unusual one. A few even prove to be ones I can raise!
Back to the original post, many varieties may look good in arrangements, but often the cuttings need to stand for a few days as first rhey may tend to wilt then revive and look better as the take up water and begin to form roots.
