Alocasia lauterbachianaAlocasia lauterbachiana has long, narrow green leaves with serrated margins and purple toned undersides indoors. The foliage grows in a lance like arrangement, giving the plant height while keeping the blades slender. Serrated edges, blade length and coloured backs make it recognisable when the leaves twist or angle outward. As petioles rise, the plant keeps a narrow vertical habit with plenty of margin detail. Chewed leaves may cause oral irritation.
