Yucca

Yucca in North Carolina?  Yes it does well here and blooms prolifically.

 

Patterns

The agave above and the yucca below look like mathematical patterns.  I'll bet if you could count each spiral it would match the Fibonacci series. 

0,1,1,2,3,5,8,13,...

Anyone want to count?

 

Yucca

I didn't realize that yucca would grow in rainy North  Carolina, but obviously it does.  I don't think I've seen this much yucca blooming all at the same time, even in California.
