Creosote Bush Blossoms — Images by kenne
If you have ever experienced rain in the Sonoran Desert, then you have experienced what is often referred to as the “smell of rain.” ** It is a pungent smell exhibiting a characteristic odor of creosote coming from an evergreen shrub from which its common name is derived.
This Scrub is the most drought tolerant perennial in North America, and it may be the oldest living plant. As the plant grows older, its oldest branches die, and its crown splits into separate crowns. Eventually, the old crown dies, and the new one becomes a clonal colony from the previous plant, composed of many separate stem crowns all from the same seed.
Often there are no other plants around creosote plants resulting in pure stands. The latest explanation for this is that the root systems of mature creosote plants are simply so efficient at absorbing water that fallen seeds nearby cannot accumulate enough water to germinate, effectively creating dead zones around every plant.

** (Because we haven’t had any rain for awhile, the “smell of rain” would be welcome about now.)
Interesting info on creosote plants. (Hope you get some rain soon. Wish we could send you some of ours….)
