Crested Dead Man's Fingers, Crested Mushroom Opuntia
Opuntia clavarioides f. cristata, Puna clavarioides f. cristata
Maihueniopsis clavarioides f. cristata is a low growing cactus up to 6 inches (15 cm) tall. The typical form has distinctive conical segments, but monstrous forms with crested fan-shaped or branching finger-like stems are widely seen in cultivation. Sometimes all 3 of these stem forms may be seen on a single plant.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Though the large variety of species within the Opuntia genus means different types of Prickly Pears may need slightly different care. All are desert cacti that need lots of sun, lots of light and very little water. If you live in a hot, arid area, these plants can generally be planted outside, left alone, and enjoyed.
These cacti will grow just fine in a garden, but they can be grown in pots as well. To repot, ensure the soil is dry, then remove the pot and knock away the old soil. After treating any cuts with fungicide, place the cactus in a new pot and backfill it with potting soil. As with a new cutting, make sure not to water a newly repotting Prickly Pear for a brief period to avoid rotting its roots.
Opuntia can propagate either by cuttings or by seed. To propagate by cuttings, sever pads from a plant and let them dry so that the wounds heal. Then place the plants in dry soil and refrain from watering them until they begin to grow to avoid rotting them. See more at: How to Grow and Care for Opuntia.
