My dad was always fascinated by smoke trees and I guess I've inherited his curiosity. While we don't have any in our yard, they are often spotted out in the desert, along the sandy washes. A lot of water is required to scratch their seeds so that they can sprout. That's why they are found in and near washes. And, their roots go far down into the sandy soil! In spring, when it is warm, they are covered with purple blossoms, but now they stand starkly against a blue sky. That's My World for Tuesday, January 5, 2010.
