Ahah! That is not something I have ever seen in any of the books I've read
about them. Sounds like the books only deal with the plants in all their
glory.  Thank you so much.

Here in Louisiana they are pretty much shot in the summer. You might get
some to stay evergreen, but you shouldn't see much active growth if at all
in the heat of summer.  They often look very ratty if they don't go dormant.
