Shop Purple Vein CormIdentification
Dark arrowhead foliage highlighted by purple veins
The main leaf in the supplied plant image has a striking pinkish-purple vein network over deep green foliage. Its pointed, heart-to-arrow-shaped outline and contrasting elongated lobes give the plant a dramatic appearance. Other leaves on the same reference plant appear greener and display paler veins, illustrating the variation that can occur between leaves.
Botanical background
This guide follows the nursery trade name Alocasia Longiloba Purple Vein, associated with Alocasia longiloba. Purple Vein describes conspicuous pinkish-purple midrib and branching veins; it should not be mistaken for a formally accepted independent species name. The botanical identity of a specific clone must be supported by the grower's parent-plant history.
Leaf shape and surface
In the owner's supplied plant image, the main leaf is elongated and arrow-shaped with paired posterior lobes, a pointed apex and a dark glossy green surface. The purple-pink central vein and curved side veins contrast sharply with the blade. Other leaves show lighter venation and different orientations.
Purple vein color
Pinkish-purple veins may appear especially pronounced on a mature, front-facing leaf. Younger foliage may differ in intensity and color. Lighting and photography can change how visible the purple tones are. The image is a reference for the named selection, not a promise of identical color on every leaf.
Light
Provide bright indirect light, avoiding harsh extended midday sun. Introduce increased brightness gradually and protect freshly sprouted leaves from sudden direct exposure. More sunlight does not guarantee stronger purple vein coloration.
Temperature and humidity
Maintain steady warm tropical growing conditions with moderate to high humidity and adequate ventilation. Protect young plants from cold drafts and rapid humidity swings. A covered rooting container may help retain humidity but should not become stale and saturated.
Water and potting mix
Use an open, breathable aroid substrate with drainage. Water according to the actual moisture and root condition, rather than a rigid calendar. An established plant may take up more moisture than a barely rooted corm.
Corm propagation
A viable corm can be placed upright in lightly damp perlite or sphagnum, LECA or a shallow-water setup. Keep the growth point exposed, maintain gentle warmth and avoid soaking the whole corm. Root development varies, and no fixed sprouting date can be promised.
Care after sprouting
Allow the roots to become established before moving a corm into a small nursery pot. Keep the potting medium airy, avoid excessive fertilizer on small roots and gradually acclimate young leaves to normal room humidity and bright filtered light.
Avoiding rot
Excess water in poorly aerated media can damage a corm. Inspect for persistent mushiness or foul odor if concerned; avoid repeatedly digging up a healthy, firm corm just to check it. Use clean containers and do not pack wet moss tightly.
Similar trade names
Longiloba Purple Vein, Longiloba Purple, Suhirmaniana Purple Vein and Watsoniana Red Vein are separately labeled selections in the collector market. Similar leaf color does not establish genetic identity or justify automatically merging them into one listing.
