The Ocotillo is a mainstay of Phoenix desert landscaping. It is made of many spiny pole-like unbranched stems. Leaves appear when some water is present. Water infrequently to push it to bloom. The ocotillo has sharp spines, so it is better to keep it away from walking paths.
The Ocotillo is available from many nurseries as bare root, it is a good idea to find out how long they have been at the nursery, because although the ocotillo is quite a tough plant, even its toughness has limits. Buying it in pot with some vegetation is a surer bet. It can be planted as such any time of the year. Care must be taken to keep the ground relatively dry. Recently planted ocotillos should be watered by spraying the canes. They can look dead for several months before sprouting leaves.
Orange flowers, 1 inch long (2.5 cm), in clusters covering the ends of the canes.
Pieces of canes stuck in the ground will grow.
