Genus: Pachyphytum
Origin
Pachyphytum oviferum is native to Mexico. It grows on rock cliffs in San Luis Potosí at about 3,940 feet (1,200 m) above sea level.
Description
Pachyphytum oviferum is a popular clump-forming succulent with chubby, pale blue-green to bluish-purple leaves arranged in a rosette at the tips of short stems. The rosettes can reach up to 4 inches (10 cm) in diameter. The stems can grow up to 8 inches (20 cm) long and 0.5 inches (1.3 cm) in diameter and are at first erect, later decumbent to pendent. The leaves are obovate to elliptic, measuring up to 2 inches (5 cm) long, 1.2 inches (3 cm) wide, and 0.7 inches (1.7 cm) thick.
The bell-shaped flowers appear in clusters on arching stalks from winter to early spring. They have cream-colored petals, apically with a faint round dark purple-red spot, and covered with greenish-white sepals. The flower stalks can grow up to 12 inches (30 cm) long.
Hardiness
USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Pachyphytum will not tolerate frosts well. Temperatures below 20 °F (-6 °C) will kill the plant, and temperatures that may go below 45 °F (7 °C) during the extended period should be avoided. It tolerates high heat and intense sunlight. As with most succulents from the Crassulaceae family, Pachyphytum can tolerate (and even appreciate) poor soil conditions, so long as it is well-draining. It can thrive in full or partial sunlight.
Allow the soil to dry before watering, and avoid getting water on the leaves. The plants will require more water in winter as winter begins its active growth season. If you are unsure when to water your plant, watch the lowermost leaves for drying signs and water them then. Pachyphytum is far more likely to survive under-watering than over-watering. The thick, fleshy leaves will appear wilted and slightly "under-full" when they need water.
One of the most common pests to houseplants is the mealybug, and your Pachyphytum may fall prey to this pest. The symptoms of a mealybug infestation are slowed or stopped growth (though in summer, this is a typical sign of dormancy).
