  • Posted by Baja_Costero (Baja California - Zone 11b) on Nov 10, 2019 8:22 PM concerning plant:
    Sonoran Desert succulent with upright cylindrical green stems and bright orange-red (rarely yellow) blooms from spring through early fall. This plant grows as a low shrub to about 3 feet tall, branching mostly at the base. Soft grown plants in cultivation may get larger. It is found in Baja California from the Central Desert south to the tip of the peninsula, on offshore islands in the Gulf of California, and in the neighboring states of Sonora and Sinaloa on the other side of the Gulf.

    Formerly known as Pedilanthus macrocarpus but recently moved to Euphorbia, with flowers that are very atypical for a Euphorbia. Reasonably common and well-behaved in cultivation. Suitable for larger containers.
