Opuntia humifusa 'Mulberry Creek'
Overview
Uses: Rock gardens and gravel gardens, hot dry slopes and south-facing beds, xeric and low-water plantings, specimen accents, outdoor containers and troughs.
Benefits: A true winter-hardy cactus for cold-climate gardens — it stays outdoors year-round to Zone 4 rather than being brought in. Flat blue-green pads carry silky yellow flowers three inches across in early summer, followed by deep red edible fruit. Established plants need no water and no feeding.

Bloom Color: Yellow
Foliage Color: Green, purpling in winter
Mature Height: Under 1 ft.
Mature Width: 2–3 ft. spread
Bloom Season: Early summer
Growth Rate: Slow
Summary
Most people are surprised there is a cactus native to Pennsylvania, Ohio, and New England, but Opuntia humifusa ranges from the Gulf Coast north into Ontario. ’Mulberry Creek’ is a selected form of it, chosen for consistent flowering and good pad color.
The flowers are the payoff. For roughly a week in early summer, three-inch blooms open along the top edges of the pads in a satiny, almost translucent yellow, often with a faint orange flush at the base. Native bees work them heavily. What follows is a deep red, pear-shaped fruit — the tuna — that ripens in fall and is edible once the fine spines are removed.
In winter the plant does something alarming to anyone who has not seen it: the pads shrivel, flatten toward the ground, and turn purple-bronze, looking for all the world like it has died. That is the survival mechanism. It pulls water out of the pads so ice cannot rupture them, and it plumps back up and greens out in spring. The one thing that will actually kill it is winter wet, which is why drainage matters more here than anything else.
Care
Mulberry Creek Prickly Pear Cactus Care
Plant in full sun — at minimum six hours, and more is better. Sharp drainage is not negotiable. Sandy, gravelly, or rocky soil is ideal; heavy clay or any spot where water stands in winter will rot the plant. On flat ground, plant on a slope, a berm, or a raised gravel bed.
Set the plant slightly high and top-dress with gravel rather than organic mulch, which holds moisture against the pads. Water lightly for the first few weeks only. After that, do not water at all except in an extreme, prolonged drought.
Do not fertilize. This plant is adapted to lean, poor soil and feeding produces soft growth that will not overwinter. If you are growing it in a container with a mostly inorganic mix, one very light spring application of slow release fertilizer is the most it should receive.
No winter protection is needed in the ground within its hardiness range — keep it dry rather than covered. Wear thick leather gloves for any handling. Beyond the visible spines the pads carry glochids, which are hair-fine barbed bristles that detach on contact and are genuinely difficult to remove from skin. Site it away from paths, play areas, and anywhere people brush past.

How Large Does Mulberry Creek Prickly Pear Cactus Grow?
Mulberry Creek Prickly Pear Cactus stays under a foot tall — typically six to ten inches — and spreads to a colony two to three feet across as the pads root and multiply. Growth is slow, and it will not spread beyond where you allow the pads to touch soil.
Additional Information
Will it really survive winter outdoors?
Yes, in Zones 4 through 9 with sharp drainage. Cold is not what kills hardy prickly pear; winter wet is. A plant in gravelly soil on a slope handles subzero temperatures without any protection.
The pads look shriveled and purple in winter. Is it dying?
No — that is the plant doing exactly what it should. It withdraws water from the pads so freezing cannot rupture the tissue, and the resulting flat, wrinkled, purple-bronze appearance lasts all winter. It rehydrates and greens up as spring warms.
What is the botanical name, and why do I see it listed differently?
We list it as Opuntia humifusa, which is how it is sold in the trade. Botanists have split the eastern prickly pears in recent years, so you may also encounter Opuntia cespitosa, Opuntia mesacantha, or the older name Opuntia compressa applied to very similar plants.
Is the fruit edible?
Yes. The red fruit ripens in fall and is sweet, and young pads are eaten as nopales. Both require careful handling to remove the glochids first — the fine barbed bristles are the real hazard on this plant, not the large spines.
Is it a native plant?
It is a nativar — a selection of Opuntia humifusa, which is native across the eastern and central United States as far north as Ontario. It is a useful early-summer pollen source for native bees. See our Native Plants of North America or Drought-Tolerant Plants collections for more.
