Vegetative apomixis is a form of asexual reproduction that enables certain plant species to reproduce without fertilisation. Several varieties of the Bryophyllum genus reproduce in this manner; the plants create dozens of baby plants, or plantlets, along the edges of its leaves. Easily propagate Bryophyllum, even if you don't have a green fingers: Simply lay a leaf on damp soil, and within a few days you will be rewarded with tiny plantlets sprouting along the edges of the leaf.
This succulent is also known as Bryophyllum calycinum or Kalanchoe pinnata. It has many nicknames, including Air Plant, Miracle Leaf and Resurrection Plant. The Bryophyllum pinnatum can grow to 6 feet tall with 8-inch leaves. Hawaii considers this an invasive plant.
