What is an arrowhead plant?
Arrowhead plant (Syngonium podophyllum), also called arrowhead vine or nephthytis, is a tropical aroid native to Central and South America. It is instantly recognizable by the distinctive arrow-shaped leaves of its juvenile stage — a shape that gives way to dramatically lobed, almost hand-shaped foliage as the plant matures and begins to climb. Cultivars span a wide palette from plain green through silver-streaked, neon lime, blush pink, and creamy white, making it one of the most varied foliage plants in the houseplant trade.
Is arrowhead plant toxic to pets?
Yes — the ASPCA lists arrowhead vine as toxic to cats, dogs, and horses. Like other aroids, it contains insoluble calcium oxalates — microscopic needle-shaped crystals — that cause immediate and intense oral irritation, excessive drooling, difficulty swallowing, and vomiting if chewed or ingested. Place it on high shelves or in rooms your pets cannot enter.
How much light does an arrowhead plant need?
Arrowhead plants grow best in medium to bright indirect light — near an east or north-facing window, or a few feet back from a brighter south or west exposure. They tolerate lower light but slow down noticeably and lose variegation in dim conditions. Direct sunlight bleaches and scorches the leaves; a sheer curtain between plant and window is the practical fix.
How often should you water an arrowhead plant?
Water about every 7–10 days, letting the top inch of soil dry between waterings. Check the soil rather than following a rigid schedule — the plant’s needs differ between summer and winter. A wilting or slightly soft leaf is a reliable early warning that it’s thirsty; mushy, yellowing lower leaves signal overwatering.
Should you let arrowhead plant climb or trail?
Given a moss pole or bamboo cane to climb, Syngonium produces its showier mature leaves — larger, multi-lobed, with deeper color — and grows more vigorously. Left to trail from a hanging basket, or pinched regularly into a bush, it stays compact with the classic juvenile arrow-shaped foliage. Both modes are attractive; the decision is largely aesthetic.
How do you propagate an arrowhead plant?
Arrowheads propagate readily from stem cuttings. Cut a stem just below a node, let the cut dry for an hour or two, then set it in a jar of water or push it into moist perlite. Roots emerge in two to four weeks. Pot into standard houseplant mix once the roots are an inch or two long, and keep the new plant in bright indirect light to establish quickly.
