Conservation Sense and Nonsense – Invasion Biology

Earlier this year, my friend, former Garden Rant columnist, Carol Reese, told me about a California blog, Conservation Sense and Nonsense, written by Sierra Club conservationist, Mary McAllister. In her thought provoking blog, Mary calls out those who engage in ethnic profiling of plant for the purpose of discrimination, something about which we have voiced

Mythops – The Art of Living Stoned

Every year, we post photos from our years long experiment growing the African native lithops (living stones) in the garden. Our success underscore our contention that so much of the information you find on-line and in books, is simply incorrect.

Our oldest patch starts flowering in early to mid November each year, growing beautifully under an overhanging rock. For all the articles about how difficult they are to grow,

That Won’t Grow Here

We love it when people tell us that certain plants won’t grow in our climate. As gardening contrarians, we thrive on proving gardening experts wrong. Below is a great example–our combination of Globularia repens (Spain, Italy) and Acantholimon halophilum (Central Turkey) thriving in the dryland crevice garden. Both have sailed through out rainy, humid, hot
