Opuntia humifusa, also known as Eastern Prickly Pear, is a native cactus renowned for its hardiness, beauty, and edible fruits. Adapted to the Quebec climate, it will bring a touch of exoticism and color to your garden.

Vibrant Flowering: In early summer, Opuntia humifusa is covered in waxy yellow flowers, 2 to 3 cm in diameter, with a red center, attracting pollinators. These flowers are followed by red fruits, called prickly pears, which ripen in late summer and are edible when fully ripe.

Flat and Spiny Pads: This cactus forms flat pads, called cladodes, of a bluish-green color. These cladodes are covered in spines, which provide natural protection and a unique texture.

Garden Uses:

  • Rock Garden: Opuntia humifusa is ideal for rock gardens, where it will bring a desert touch and interesting texture.
  • Native Garden: As a native plant, it fits perfectly into a natural garden and attracts local wildlife. It will attract pollinators and contribute to the biodiversity of your garden.
  • Edible Garden: Its fruits, prickly pears, are edible and can be used to make jams, jellies, and other delicacies.
  • Xeriscape Garden: Its drought resistance makes it an excellent choice for water-wise gardens.

Growing Tips:

  • Exposure: Full sun.
  • Soil: Well-drained, poor, sandy or gravelly. Tolerates dry and poor soils.
  • Watering: Moderate in summer, very limited in winter. Allow soil to dry between watering.
  • Hardiness: Zone 4a (-34°C). Very resistant to the cold Quebec climate.
  • Maintenance: No special maintenance required.

Caution: Handle Opuntia humifusa with care due to its spines. Wear thick gloves when planting and maintaining.

Note: The scientific name of this species has been changed from Opuntia humifusa to Opuntia cespitosa.
