I grew P. incrassatum in Tucson, Az in a raised bed in Arizona's sandy clay. The bed was watered twice a week, on my irrigation system, all year. The plant went dormant for the summer and didn't seem to mind the water. It did beautifully for the four years I lived there. We were at a 3,000 foot elevation with intense sun. I brought it with me when I moved to Florida and it is just beginning to show some growth after being dried off this summer. After reading that wonderful introduction...I shall have to grow more pelargoniums. Lynn Makela Sun City Center, FL Waiting for fall
