Venus Fly Trap (Dionaea muscipula) is a very variable, rosette forming perennial with rounded, yellow-green to red leaves with winged stalks. Each leaf has 2 hinged lobes with 15-20 stiff, marginal spines. Winter and Early summer leaves are 3" long with traps 1" long; many plants also produce summer leaves to 6" long, with traps 1 1/4" long and flatter, narrower stalks.
Venus Fly Trap (Dionaea muscipula) Care: When grown indoors, grow in acidic mix of equal parts peat moss and sand in full or bright filtered light, or in a terrarium in bright light. Keep wet by standing in saucer with 1/2" of water. Growth stops in autumn, leaving swollen leaf bases in a bulb like structure below soil level; keep just moist when dormant. Pot on each spring as new growth appears. To encourage trap production, pinch out emerging flower stems and remove dead traps.
