I was waiting to see if Harold Koopowitz would answer this question; however,
I'll give a particular answer.  I bought three of these at a University of California at
Irvine arboretum plant sale years ago when Harold was the arboretum director.
One has survived.  It is located about 10 feet east of the trunk of a camphor
tree and within the drip line.  It has formed a small clump with three or four
flowering scapes each summer.  In my climate, it is green year round.  This is
a Mediterranean climate where it rains in the winter.  I water it in the summer.
This is U.S.D.A. hardiness zone 9, specifically 37°40´18.95˝N 121°47´14.60˝W
at elevation 458 feet.  This is in northern California.  Since UCI is in southern
California, I would imagine most of the Agapanthus africanus ssp. walshii
from their plant sales are in southern California, in or near Orange County.
