A passage from Wild Edible Plants of Arizona:

A native small tree, Redbud is most populous in California. However, if fortunate enough to be meandering within Havasu and Kanab Canyons, the Grand Canyon, and related terrain further to the east, look for Redbud on the sides of primary and secondary drainages.

A passage from Wild Edible Plants of California (Vol 1):

Developing before the leaves in the spring, the flowers are eaten as is or mixed with other foods as an accent. They are pleasant tasting with a hint of nectar sweetness.
