Devil’s Tongue Barrel (Crow’s Claw Cactus)

About Devil’s Tongue Barrel

Devil’s Tongue Barrel is a compact desert cactus grown for its blue-green body, strong vertical ribs, and distinctive flattened hooked spines. Even when young, it has a sculptural look that makes it stand out in a pot, and over time it becomes more barrel-shaped while still staying relatively manageable in size.

The spines are a major part of its appeal. They often show warm tones such as red, copper, or straw-gold against the cooler skin of the plant, which gives it a more dramatic and finished appearance than many simple green cacti.

When mature and well grown, it can also produce a ring of funnel-shaped flowers near the crown in shades of purple, magenta, or yellowish tones. Devil’s Tongue Barrel usually performs best when treated as a true desert cactus that wants strong light, excellent drainage, and long dry intervals between waterings.

How to Care for Devil’s Tongue Barrel

Watering

Water deeply but rarely. During the warm growing season, soak the mix thoroughly until water runs from the drainage holes, then let the soil dry out almost completely before watering again.

This usually means waiting many days, or sometimes longer, depending on heat, light, and pot size. In autumn and winter, reduce watering sharply and keep the plant on the dry side. Cool, damp soil is the main danger and one of the fastest causes of rot.

Sunlight

Give Devil’s Tongue Barrel as much light as possible, ideally full sun. A south- or west-facing windowsill with several hours of direct light is usually the best indoor position.

If the plant has been in lower light, move it into stronger sun gradually to avoid scorch. In weak light it often loses its neat rounded shape, while in strong light it stays more compact and develops better body and spine color.

Temperature

Keep the plant warm in the growing season, roughly within the 64–77°F (18–25°C) range. Warmth supports stronger growth and better overall form.

In winter, a cooler but frost-free rest is useful as long as the mix stays almost dry. Avoid cold wet conditions, because chilled roots in damp soil are much more dangerous than cool dry air.

Humidity

Devil’s Tongue Barrel prefers low humidity and good air movement. Normal dry indoor air is usually not a problem for this plant.

Do not mist it, and avoid persistently humid stagnant conditions, especially if watering is already on the generous side. Water belongs in the soil, not on the cactus body and spines.

Soil

Use a very fast-draining, sandy, loose cactus mix. A mineral-heavy blend with pumice, perlite, coarse sand, and fine gravel usually works much better than a richer, moisture-holding potting soil.

The goal is a root zone where water runs through quickly and does not linger around the roots. A relatively small pot with wide drainage holes is usually safer than a large deep container that stays damp too long.
