Sander's alocasia is a tropical aroid from Mindanao, grown for its dramatic, glossy, dark leaves with bold pale veins. It needs warmth, humidity and consistent moisture, and should be kept away from pets and children.

About
Alocasia sanderiana, commonly known as the kris plant or Sander's alocasia, is a plant in the family Araceae. It is endemic to Northern Mindanao in the Philippines, but is commonly grown as an ornamental plant worldwide. It is classified as critically endangered in the wild by the International Union for Conservation of Nature.
How to grow it
Alocasia plants are cultivated in pots as indoor plants in a substrate of sod, peat, humus and sand (2:2:3:2) with moss or pieces of charcoal added. In spring and summer give a liquid compound fertiliser 2 times a month. Alocasia needs extra light in winter; it grows better with high air humidity. Ambient air humidity is maintained at 80-85%. In spring and summer, the Alocasia needs regular watering and frequent spraying. Multiply by grafting, dividing rhizomes or sowing seeds in spring in a warm place. In winter the temperature needs to be relatively high - not lower than 17 °C (63 °F) for all the species described, in summer the optimum temperature is 21 °C (70 °F). In domestic conditions, water abundantly during the growing season as soon as the soil surface in the pot dries out, from autumn watering is reduced, and in winter moisten the soil only after a day or two after the top layer of substrate dries out. The soil should not be allowed to dry out, but excessive moisture is also extremely harmful.
Uses
A. sanderiana is cultivated as an ornamental plant, for its large dramatic foliage. In nontropical climates, it is used as a house plant. It is also used in making nanomaterials to fight bacteria in vitro.
