Aporocactus malisonii (Rat Tail Cactus) – Trailing Cactus Houseplant UK

Aporocactus malisonii (Rat Tail Cactus) is a distinctive trailing cactus prized for its long, slender cascading stems and elegant growth habit. Unlike upright desert cacti, this species develops soft, flowing stems that drape naturally over the edge of its pot, creating movement and softness in a room. Supplied in a 14cm pot, it is perfectly sized for shelves, windowsills or hanging planters, where its trailing form can develop and mature over time.

Often searched for as the Rat Tail Cactus, trailing cactus, or hanging cactus houseplant, Aporocactus malisonii offers something genuinely different. Its stems begin upright when young, then gradually arch and cascade as they lengthen, forming graceful strands that can eventually reach impressive lengths indoors. Mature plants may also produce vivid pink tubular flowers, adding seasonal colour and reinforcing its reputation as one of the most beautiful trailing cactus species for indoor growing.

This is a plant that rewards patience. It settles quietly into its environment, grows steadily, and becomes more characterful with age — a true long term houseplant that develops presence rather than demanding attention.

Native habitat and growth pattern

Aporocactus malisonii is native to Mexico, where it grows on rocky slopes and in dry forests, often trailing from elevated positions or clinging to rock faces. This natural trailing habit allows it to capture light efficiently while avoiding excessive ground moisture.

As an indoor plant, Aporocactus malisonii grows steadily, producing slender cylindrical stems that can eventually cascade well beyond the pot. Unlike many desert cacti, its growth habit is naturally pendulous rather than upright, making it especially valuable as a hanging cactus or trailing shelf plant. Growth remains controlled and elegant rather than aggressive.

Styling at home

• Ideal as a trailing cactus for shelves and bookcases
• Perfect for hanging planters where stems can cascade freely
• Works beautifully in small ceramic pots or minimalist containers
• Excellent for bright windowsills in living rooms, bedrooms or offices
• Adds natural movement and softness to structured interiors

Care guide for Aporocactus malisonii (Rat Tail Cactus)

Light requirements
Aporocactus malisonii grows best in bright light and benefits from several hours of gentle direct sun each day. As a trailing cactus native to Mexico, it thrives on bright windowsills, particularly south or west facing positions. Adequate light supports strong stem growth and encourages flowering in mature Rat Tail Cactus plants.

Watering
Water Aporocactus malisonii only when the compost has fully dried out. This trailing cactus stores moisture in its stems and is highly sensitive to overwatering. During spring and summer, watering every two to three weeks is usually sufficient. In winter, reduce watering significantly to prevent root rot.

Feeding
Feed Aporocactus malisonii once per month during spring and summer using a diluted cactus fertiliser. This supports healthy stem development and flowering. Avoid feeding during autumn and winter.

Temperature
Aporocactus malisonii thrives in normal indoor temperatures between 15°C and 25°C. As a Mexican cactus, it prefers warmth and should be protected from prolonged cold or draughts.

Pet safety
The Rat Tail Cactus is not considered pet safe due to its fine spines, which may cause irritation if handled or chewed.

Propagation
Aporocactus malisonii can be propagated easily from stem cuttings. Allow cut stems to dry and callous for several days before planting into dry cactus compost. This trailing cactus roots readily and produces new plants with minimal effort.
