Be very careful in watering these plants. They will die easily if they are watered too often or fertilized too much. They have a tendency to be a “nurse” plant for others in their shadow. Creosote in the front and back. The difference? The ones in the front were along a desert road and were cut off by a road grader. The ones in the back were not and got woody. That’s the secret if you want them small and bushy. Cut them to the ground when they are established and let them regrow.
