(The fungus also destroys the flowering structures of the plant, so it does not make seed, but the plants can still be propagated asexually by rhizome.) In an environment such as a rice paddy, new sprouts of wild rice are easily infected ...

Jade plants may readily be propagated from both with success rates higher than with cuttings. In the wild, vegetative propagation is the jade plant's main method of reproduction. Branches regularly ...
