Light: Easy to see why he's called the Arrowhead Plant, with the spade-like shape of his leaves. He'll flourish in bright indirect light. Too much direct sun will scorch his leaves.
Water: He likes lightly evenly moist soil, so check on him regularly and give him a drink when 1/3 of his soil is dry. He’ll need a lot less water in winter. He likes high humidity, so get that mister out!
Food: Feed him once a month during spring and summer.
PM tip: Variegation occurs in his leaves when there is more light, so consider moving him to a brighter spot if his leaves become dark.
As with many houseplants, he can be mildly toxic if ingested.
