New Guinea Gold is an oddity in the Aroid world. It is the only Alocasia that goes through cycles of variegation. The leaves are normally a deep, rich green accented by yellow to pinkish petioles and veins. For an unknown reason, the plant will change color. Its leaves will become spotted or splotched with vivid patches of yellow or will turn completely yellow. Later, the same leaf will become green again. It is a fascinating plan to watch grow and change from year to year. It can reach 8 feet, under the right conditions, and does well in full to part sun. It does not do well in full shade. It needs to be in moist but well drained soil.
