Cambium
Propagation and reproduction
Definition: A layer of meristematic tissue that produces new phloem on the outside, new xylem on the inside, and is the origin of all secondary growth in plants.
How it applies to plumeria: Cambium can relate to cuttings, rooting, grafting, seed pods, seedlings, or pollination. These details help explain how a plumeria is reproduced and whether a plant is a clone, a seedling, or a grafted plant.
What to look for: Record whether the observation came from a cutting, grafted plant, seedling, pod parent, or pollen parent. Propagation notes are useful, but they should be kept separate from visual identification traits.
Identification note: This term is one clue. A plumeria should be compared using all available traits, photos, source history, and growing context rather than a single characteristic.
- Glossary: GirdlingGirdling: From a woody stem, the removal of a ring of bark extending inward to the cambium. Plumeria context is explained on the term page.
- Glossary: Girdled or girdlingGirdled or girdling: The damaging, cutting, removing, or clamping of cambium all the way around a trunk or branch. Sometimes, girdling is done deliberately to kill an unwanted... Useful as a plumeria naming clue.
