Re: Aesculus californica

The RHS Dictionary lists it as zone 7.

I was growing it on my unwatered roadside bank, and it was doing well and
looking handsome.  Then I read, in one of my beekeeping books, that it had
a toxic effect on bees, and I ripped my shrub out.  This was about 30
years ago, so I might have the details wrong.  The pollen, which is fed to
the larvae, must be mutagenic.  The malformations were first thought to be
from pesticides, but then discovered to be from the buckeye pollen.
