Yes, a rubber plant (Ficus elastica) can be propagated from a leaf cutting, although it's more readily propagated by stem cuttings.
While a single rubber plant leaf can root and survive for a period, it will not typically grow into a full, new plant without a node. The node is the area where the leaf attaches to the stem and contains the necessary meristematic tissue for new growth.
Here’s a breakdown:
-
Rooting is Possible: A rubber plant leaf can indeed root if placed in water or soil. The leaf will often develop roots, giving the appearance of successful propagation.
-
Growth Stalls Without a Node: However, without a portion of the stem (including a node), the leaf will generally not produce new stems or leaves. The rooted leaf will persist for some time but will not develop into a fully formed rubber plant. It essentially remains a rooted leaf.
-
Stem Cuttings are More Reliable: For successful propagation leading to a new rubber plant, stem cuttings are the preferred method. These cuttings include a node and are more likely to produce new growth.
-
Leaf Cuttings Can Work (Sometimes): While uncommon, it's theoretically possible to get a new plant from a leaf cutting if it contains a small piece of the stem, including a dormant bud. This is less reliable than using a dedicated stem cutting.
In summary, while a rubber plant leaf can root, it typically won't grow into a new plant on its own without a node. Stem cuttings offer a much higher success rate for propagating new rubber plants.
