Dieffenbachia (Dumb Cane)
Dieffenbachia seguine
Family Araceae
Dieffenbachia fills a room the way few houseplants can: big, splashy leaves marbled cream and green, 2 to 5 feet of instant tropical presence that keeps its looks even in the dim corners most plants refuse. For bold foliage per dollar, the old dumb cane is still hard to beat.
Famously forgiving of low light and lapsed attention, it suits offices and grown-up households best: the sap genuinely numbs the mouth — that's the 'dumb cane' name — so homes with pets or toddlers should admire it elsewhere. Given a safe shelf and a shady room, it repays neglect with presence.
