Program: Doug Dawson, Lithops: The Wild and the Tame
Doug began his passion for Lithops in the 1990’s. Previous to then, he would occasionally buy one and shortly thereafter kill the poor thing. During the last 20 years he has grown most of his lithops from seed in the extremely harsh desert climate of Phoenix.
The four summer months have regular temperatures at night around 90 degree and days around 110 degrees. Doug will discuss what it takes to keep these colorful “living stones” alive.
The presentation will include many photos of what the plants look like in habitat in Namibia and South Africa. Then photos of plants in Doug’s collection will be shown, with many colorful cultivars as well as many of the species and varieties.
For those of you who are not yet open to including lithops in your collection, it is hoped that you will be convinced to give them a try.
