I'm sure they'll replant. |
San Antonio is in a very interesting spot, botanically speaking. Of any city in Texas, that would be the one I'd most want to visit.
As far as these once-in-40-years cold snaps go, they could always get away with more Sabals and Trachies if they wanna dial back on the Washies and CIDPs.
The durational cold there this month, plus the 7b/8a minimums are a blessing in at least one sense: There will be Washie, Phoenix, and other Zone 9 palms where there will be deaths AND survivors. Palm enthusiasts need to get seed from the survivors after this coming growing season. By constantly following this practice, we push natural selection ahead a little faster than it would go on its own. In my own lifetime, I've seen the advent of 6b/7a bulletproof Crape Myrtles and Magnolia grandifloras. We're even starting to see Zone 6b camellias. With palms, we have to encourage cold hardiness by favoring seed from hardy stock.
