Ferocactus latispinus (commonly called the Devil’s Tongue Barrel or Mexican lime cactus) is a small to medium-sized barrel cactus native to central and eastern Mexico. It forms solitary, ribbed, globular to slightly cylindrical stems up to about 30–60 cm (12–24 in) tall, with 10–18 broad ribs. Spines are stout, flattened, and often hooked or curved—typically a mix of yellow, red, brown, or gray—giving the plant a distinctive, dramatic appearance. In summer it produces funnel-shaped flowers in shades of yellow to red or orange near the stem apex, followed by edible, fleshy fruit. Its sculptural form and colorful spination make it a popular choice for rock gardens, cactus collections, and drought-tolerant containers.

Light

Provide full sun to very bright light. A south- or west-facing window is ideal indoors. Outdoors, give several hours of direct sun; some afternoon shade in very hot climates prevents sunburn.

Temperature

Thrives in warm conditions. Optimal: 70–95°F (21–35°C) during growing season. Tolerates down to about 40–50°F (4–10°C) in winter if kept dry. Protect from frost.

Soil

Use a fast-draining cactus or succulent mix. Ideal mix = gritty, mineral-rich substrate with coarse sand or perlite and some gravel. Avoid heavy, moisture-retentive soils.

Watering

Water thoroughly during active growth (spring–early fall), then let the soil dry completely between waterings. Reduce watering significantly in winter — only enough to prevent extreme shriveling. Overwatering leads to root rot.

Humidity

Low humidity is preferred. Normal indoor humidity is fine; avoid persistently humid environments.

Fertilizer

Feed lightly during the growing season (spring and summer) with a balanced, diluted cactus fertilizer (low nitrogen), about once every 4–6 weeks. Do not fertilize in winter dormancy.

Flowering

Produces funnel-shaped flowers in spring to early summer when mature and well-cared-for. Good light and a cool, dry winter rest encourage blooming.
