Summary

Opuntia macrorhiza, commonly known as Plains Pricklypear, Prairie Pricklypear, Western Pricklypear, Twistspine Pricklypear, or Grassland Pricklypear, is an evergreen succulent native to arid and semi-arid regions, including prairies, grasslands, and open areas throughout the South-Central United States and Northern Mexico. This low-growing cactus typically forms clumps that are rarely over 30 cm (1 foot) tall, spreading horizontally. Its pads are green and often have a twisted spine, giving rise to the name Twistspine Pricklypear. The flowers are particularly showy, with bright yellow petals that often feature red markings near the base, blooming in late spring to early summer. The fruits are narrow, red, juicy, and edible, attracting various wildlife.

Plains Pricklypear is valued for its drought tolerance and striking yellow flowers, which can add a splash of color to rock gardens, xeriscapes, and desert-themed landscapes. It is also used in native plant gardens to support local ecosystems. This cactus requires minimal maintenance, thriving in full sun and well-drained soils. It is tolerant of poor soils and needs very little water once established. While it is generally disease-resistant, overwatering can lead to root rot. It is important to handle with care due to its spines and glochids, which can cause skin irritation.CC BY-SA 4.0
