Monstera deliciosaMonstera deliciosa builds a thick climbing stem with long leaf stalks and aerial roots that anchor the vine as it rises.Young plants have glossy, whole leaves with a broad heart-shaped outline, so a small plant can look very different from the mature form. Leaf shape changes only on new growth; an open leaf keeps the outline it already has.On established climbing stems, later leaves can become much larger. Deep cuts reach in from the margins and enclosed openings form nearer the midrib, creating the familiar Monstera outline across a broad, substantial leaf.
