Monstera SiamA very cool, rare type on Monstera that, like a lot of other Monstera varieties, will develop fenestration as it matures. As a climber, it will grow larger leaves if you give it a trellis, moss pole or bamboo stake to climb on. They really thrive in bright, indirect light but will tolerate medium light. Water when the top 2 3" of soil begin to feel dry. They are considered slightly toxic if eaten.
