Runner-up: Elizabeth Barrett Browning. I use GIMP.
Here's the quote in context:
My friend Scott Calhoun, who designs gardens in Tucson and knows about drought, once said to me (quoting someone else, and I’m sorry I’ve forgotten who), “How do you know it’s drought-tolerant if you water it?”
And here's the source: The No-Water California Garden by Amy Stewart, over on Garden Rant. Amy lives and gardens in Eureka, California, which apparently does not share SoCal's monsoon season. (Hope she waters her trees.)
That last link reminds me that Emily Green, who needs no introduction to SoCal gardeners, is moving to the East Coast. We're not taking the news well.
It's official: California is doomed. https://t.co/sUKr49U47k— Chris Clarke (@canislatrans) July 20, 2015
See some photos of Emily's Altadena garden here. Her blog is here. Her influence is everywhere, though I think she'd protest that most of us (cough*I own a leaf blower*cough) don't seem to have learned a thing. California will miss her.
