How to read these values
These care values are quick reference points for indoor growing. Use them as a guide, then adjust for pot size, substrate, temperature and how quickly the substrate dries.
For more detail, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” shows how far the substrate should dry before watering again.
- Substrate: structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks the cold-stress threshold.
- Humidity: target range; steady conditions usually matter more than exact numbers.
- Growth habit: how the plant grows, such as upright, climbing, trailing, clumping or rosette-forming.
- Support: whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: expected pace under suitable indoor conditions; use as a guide, not a promise.
- Max size indoors: realistic long-term indoor size under good conditions.
- Toxicity & safety: irritation, toxicity or physical hazards such as spines or bristles.
- Origin & habitat: native range, hybrid background or typical habitat where relevant.
- Outdoor growing: when a potted indoor plant can be placed outside and what outdoor protection it needs.
Alocasia longiloba ‘Purple’
Alocasia longiloba ‘Purple’ is a purple-backed Alocasia in the longiloba group, with glossy dark green leaves, pale vein structure and a rich purple underside. Its leaves are sagittate, meaning arrow-shaped, with defined basal lobes, a broad pointed blade and raised veins visible on the reverse.
Alocasia longiloba ‘Purple’ grows from a rhizome, a thick stem-like base with long petioles and a clear purple leaf reverse. It needs filtered light, an airy mix and steady moisture around the roots.
Glossy upper surface, purple reverse
The upper surface is dark green and glossy, sometimes with faint pinkish tones as the blade hardens. Pale veins run from the central midrib into the blade, while the underside develops purple to maroon-purple colour with raised vein detail. When the leaves angle outward, the purple reverse becomes easy to see.
Petioles are long and rise from the rhizome. A mature plant may carry a smaller number of larger leaves. New leaves can open softer and lighter, then deepen in colour as the tissue firms.
Care for Alocasia longiloba ‘Purple’
- Light and colour: Bright indirect light helps the petioles hold and supports stronger colour on mature leaves.
- Watering: Let the top layer dry slightly before watering again. The lower mix should stay fresh and open.
- Substrate: Use an airy mineral-organic mix with bark, coco husk and coarse drainage.
- Temperature: Keep the root zone warm, especially after watering.
- Humidity: Steady humidity reduces edge stress on the long blades.
- Feeding: Use diluted balanced feed while new leaves are forming, when warmth and light are strong enough for active growth.
- Rhizome care: Keep the rhizome stable in an open mix.
Reading the purple-backed leaves
The purple underside can make pests and early stress harder to see. Inspect the backs of leaves, petiole bases and the raised veins when new growth is soft. Clean mature leaves gently with a damp cloth while supporting the blade.
Common signals:
- Faded purple underside: Leaf age, weak light or low plant strength can make the reverse look duller.
- Yellowing after watering: The lower mix may be too wet or too cool.
- Weak petioles: Roots, light direction and pot stability are the first checks.
- Small next leaf: Transport, root disturbance, old substrate or a seasonal pause can reduce size for one cycle.
- Brown margins: Humidity, watering gaps and mineral build-up are the usual causes.
After an older leaf has fully faded, cut it at the base with clean scissors. Propagation works best from firm offsets, divisions or rhizome sections while the plant is actively growing. Mature longiloba-type plants can produce solitary or paired inflorescences with a spathe and spadix, followed by orange-red fruits.
Alocasia longiloba ‘Purple’ contains calcium oxalate crystals. Place it where pets and children cannot reach the leaves or cut sections. The cultivar name refers to the purple tones on the underside of mature leaves.
