The Fishbone Cactus (Epiphyllum anguliger) is an epiphytic jungle cactus native to the rainforests of Mexico, instantly recognised by its long, flat, deeply lobed stems that resemble a fish skeleton. Unlike desert cacti, it grows naturally on tree branches, so it enjoys bright but filtered light and a little more moisture.
In Indian homes it makes a striking trailing houseplant for hanging baskets, shelves and balconies, with arching stems that can reach 60-90 cm. Mature, well-rested plants may produce large, fragrant white-to-cream nocturnal flowers in the cooler months.
It is low-maintenance, forgiving of occasional neglect and easy to propagate from stem cuttings, making it a favourite for beginners and collectors alike.

Care guide
| Sunlight |
Bright indirect light; an east or north window or shaded balcony. Avoid harsh direct afternoon sun, which scorches the stems. |
| Watering |
Water when the top 2-3 cm of soil dries out; keep lightly moist in growth, reduce in winter. Never let it sit in water. |
| Soil / mix |
Well-draining, airy mix; e.g. potting soil with coco peat, perlite/sand and some orchid bark or compost. |
| Temperature |
Ideal 18-28 C. Protect from temperatures below 10 C; bring indoors during cold north-Indian winters. |
| Humidity |
Prefers moderate to high humidity (50%+); mist occasionally or group with other plants in dry seasons. |
| Fertilizer |
Feed monthly in spring-monsoon with a balanced or low-nitrogen liquid feed; a high-potash feed in autumn aids flowering. Stop in winter. |
| Pruning |
Minimal; trim leggy or damaged stems to shape and encourage branching. Cuttings can be replanted. |
| Repotting |
Repot every 2-3 years or when rootbound, preferably after flowering; it flowers better when slightly potbound. |
| Propagation |
Easy from stem cuttings: let the cut end callus for a few days, then plant in moist, well-draining mix. |
| Pests & problems |
Generally hardy; watch for mealybugs, scale and spider mites, especially indoors in dry air. Treat with neem oil. |
| Toxicity / safety |
Considered non-toxic and pet-safe; not known to be poisonous to cats, dogs or humans. |
| Difficulty |
Easy |
Uses
- Decorative trailing plant for hanging baskets, shelves and balcony railings.
- Indoor greenery for living rooms, offices and well-lit bathrooms.
- Collector's plant for cactus and succulent enthusiasts.
- Easy gifting plant for beginners due to its low-maintenance nature.
Growing tips
In most of India, grow it in bright shade rather than full sun; an east-facing balcony or window is ideal. During the hot, dry summer (Apr-Jun) move it away from direct sun and water a little more often, but ensure the pot drains freely.
Use the monsoon and post-monsoon months for active growth and feeding. To trigger flowering, give the plant a cooler, drier rest in late autumn/winter with reduced watering and slightly cooler nights. In northern India, shift it indoors when winter temperatures drop below 10 C.
