The Story
Plant Bio
Opuntia humifusa is a low-growing, spreading cactus native to a wide range of eastern and central North America. It consists of flattened, green stem segments called pads or cladodes, which are armed with sharp spines and tiny, irritating bristles called glochids. This species is remarkably cold-hardy for a cactus, surviving in zones as cold as 4. It produces large, showy, bright yellow flowers in early summer, followed by edible, reddish-purple fruits known as tunas.

Planting
How to Grow
- Select a location in full sun with sandy or gravelly soil.
- Ensure the site has perfect drainage, especially in winter.
- Lay a single pad flat on the soil surface or plant it one-third deep.
- Do not water for the first few weeks to prevent rot.
- Roots will form from the areoles touching the soil.
- Water only sparingly during the hottest, driest parts of summer.
Pro Tip
Handle with thick leather gloves and tongs to avoid contact with the nearly invisible, irritating glochids.
