Botanical Name: Opuntia salmiana
Common Name: Giant Prickly Pear
Opuntia salmiana is a large, striking prickly pear cactus native to Mexico. It features broad, paddle-shaped pads with robust spines and can produce vibrant yellow flowers. Hardy and drought-tolerant, this cactus makes a dramatic statement in gardens, xeriscapes, or large containers. Mature plants can reach 10–15 feet tall and spread widely, forming an impressive architectural presence.
Care and Cultivation:
Thrives in full sun
Water sparingly; allow soil to dry completely between waterings
Use a well-draining cactus or succulent soil mix
Suitable for large gardens, rockeries, or containers
Frost Tolerance and Cold Hardiness:
Best suited for USDA Zones 9–11
Can tolerate brief frost down to about 28°F (-2°C)
Prolonged freezing temperatures may damage pads and growth tips
Protect or move indoors when severe cold is expected
Winter Dormancy and Health:
Growth slows or pauses during winter dormancy
Reduce watering significantly in cooler months
Pads may appear slightly wrinkled or dull in winter; this is normal and not a sign of poor health
Note: Handle with care—pads have strong spines and glochids
