William:

I am friends with Yucca-Do and Madalene Hill.  They have frequently told me
about the weather transition zone that covers much of southeastern Texas.
It is the sudden changes in temperature and shifts in humidity that ruin
Mediterranean plants.  Even though the temperature is warmer than necessary
for overwintering, the plants get fooled out of dormancy often enough to
kill them.  The ability to withstand these changes is what made the rosemary
variety `Arp' popular some years ago.
