The natural variation can also be influenced by your growing conditions. I had some tall Brazilians that got to over 30 feet because of shading.

On a similar note, has anybody had a spontaneous mutation (sport) in any of their clumps?

I would imaging that extreme conditions are the largest instigation of sporting?

Maybe extremely favorable conditions can do it just as easily as not so favorable conditions?

I bought a hybrid long stem rose that got ignored and "died". I hit it with some water and up came a little white tea rose...
