Page Three, The Sonoran Desert
George And Audrey DeLange
Plants shown on this page bloom a little later than the others shown on the previous two pages, of the lower elevations, of the Sonoran Desert. Then, about the time, that the same species of plants stop blooming in the lower elevations; the same species start blooming in the upper elevations, of the Arizona, Sonoran Desert. Sometimes they will be blooming in both elevations during late March and early April. Remember that the variables of temperature and rainfall have a great effect upon the plants and animals in the Merriam Life Zones. In general, these plants bloom from about the last week of March through the month of June.
