Opuntia Polyacantha Inermis - Spineless Plains Prickly Pear

Opuntia polyacantha ‘Inermis’, commonly known as the Spineless Plains Prickly Pear, is a unique cultivar of the hardy North American cactus species. Distinguished by its flattened, succulent pads and absence of spines, this variant offers a smooth, elegant texture while retaining the natural resilience and architectural form characteristic of Opuntia polyacantha. Its low-growing, clumping habit creates a striking, sculptural presence in both xeriscape gardens and curated plant collections.

At TOMs FLOWer CLUB, each Opuntia polyacantha ‘Inermis’ is carefully propagated from our personal collection, ensuring a healthy, slow-growing specimen with a well-established root system. Potted in a self-mixed, highly permeable organic substrate, it enjoys optimal drainage and aeration, supporting long-term vitality and the development of its distinctive, spineless pads.

Care Overview:

• Light: Thrives in full sun; essential for compact growth and optimal pad coloration.

• Watering: Low; allow the soil to dry completely between waterings, particularly during winter dormancy.

• Temperature: Hardy to approximately -15 °C when grown in dry, well-drained conditions.

• Growth: Slow-growing; minimal maintenance required, ideal for collectors seeking unusual, sculptural cacti.
