Beavertail Prickly Pear (Opuntia basilaris) – A Stunning, Low-Maintenance Cactus for Phoenix Valley Landscapes
The Beavertail Prickly Pear, scientifically known as Opuntia basilaris, is a striking and resilient cactus native to the southwestern United States and northwestern Mexico. Known for its distinctive flat, paddle-shaped pads and vibrant, colorful blooms, this cactus is a perfect addition to desert landscapes in the Phoenix Valley.
Size and Growth
The Beavertail Prickly Pear typically grows to 2 to 3 feet in height, while spreading outward to form dense clumps up to 4 to 6 feet wide. The plant's blue-green, oval pads lack large spines but are covered in tiny glochids, which are small, hair-like spines that should be handled with care. This cactus’s clumping growth habit makes it ideal for ground cover or as a focal point in desert gardens.
Gorgeous Spring Blooms
In spring, the Beavertail Prickly Pear produces large, showy flowers in shades of pink, purple, or magenta, creating a vibrant contrast against its blue-green pads. These flowers are followed by dry, spiny fruits, adding further interest to the plant throughout the year.
Perfect for Xeriscaping in Phoenix
This cactus thrives in full sun and prefers well-draining soil, making it perfectly suited for xeriscaping and water-wise gardens in the Phoenix Valley. Its ability to tolerate extreme drought conditions means it requires minimal watering, making it an excellent choice for low-maintenance landscapes.
Ecological Benefits and Edibility
The Beavertail Prickly Pear is a great addition to native plant gardens and wildlife gardens. Its beautiful flowers attract pollinators, while the fruits provide food for birds and other desert wildlife. The nopales (pads) of the cactus are also edible, commonly used in various culinary dishes, although the glochids must be carefully removed before consumption.

Three Timbers Installation Guide (Feel Free to Follow): Beavertail Prickly Pear
Planting Guide:
- Location: Full sun (at least 6 hours of direct sunlight daily for optimal growth)
- Soil: Well-drained, sandy, or rocky soil (slightly acidic to neutral soil preferred)
- Spacing: Space plants 3-5 feet apart to allow for the mature size and ensure proper air circulation
- Planting Depth: Plant the cactus at the same depth as the root ball, ensuring the top of the root ball is level with the surrounding soil surface
- Support: No staking required; Beavertail Prickly Pear is self-supporting and naturally forms a compact, low-growing cluster
Watering Guide:
Watering After Planting:
- Initial Watering: Water thoroughly immediately after planting to saturate the root ball and surrounding soil
- Frequency: Water every 3-4 days for the first 2-3 weeks to establish the root system
- Watering Amount: Provide 1 inch of water per session to ensure deep watering around the roots, but ensure the soil drains well to avoid standing water
When is the Plant Established?
- Timeframe: Beavertail Prickly Pear is considered established after 3-4 months when the roots have spread into the surrounding soil and the plant begins showing consistent new growth
Watering Once Established:
- Summer: Water every 7-10 days during the hotter months. If temperatures exceed 100°F, increase watering to every 5-7 days. Provide 1.5-2 inches of water per session.
- Winter: Water every 3-4 weeks during the cooler months, depending on rainfall. Beavertail Prickly Pear is drought-tolerant once established, but it still benefits from occasional deep watering during dry winter periods.
Drip Irrigation Setup:
- Placement of Emitters: Place the drip emitters 12-18 inches away from the base of the plant to ensure the water reaches the root zone. Avoid excessive moisture around the base to prevent rot.
- Flow Rate: Use emitters with a flow rate of 1-2 gallons per hour for slow, deep watering. This allows water to penetrate deep into the soil, promoting healthy root growth.
- Number of Emitters: Place 1 emitter per cactus or around the base of the plant to ensure even water distribution. Adjust the number of emitters as the plant matures.
- Irrigation Zone: Set up a dedicated irrigation zone for cactus and drought-tolerant plants like Beavertail Prickly Pear, allowing for precise watering according to their specific needs.
- Adjusting Frequency: In the summer, you may need to increase watering frequency to every 5-7 days to ensure the plant gets enough moisture, especially during extreme heat. In winter, reduce watering to every 3-4 weeks or adjust based on rainfall.
General Watering Tips:
- Soil Check: Check the soil moisture regularly. Water when the top 2-3 inches of soil feel dry to the touch.
- Avoid Overwatering: Beavertail Prickly Pear is drought-tolerant and thrives in well-drained soil. Overwatering can cause root rot, so be sure the soil drains well and avoid standing water around the cactus.
- Mulch: Apply a thin layer of mulch around the base to help retain moisture and keep the roots cool, but avoid placing mulch directly against the cactus pads to prevent rot.
