Seed dormancy
Growth habit
Definition: An adaptive feature of some plants to keep the seeds from germinating until conditions exist that favor seedling survival.
How it applies to plumeria: Seed dormancy can describe how a plumeria grows as a woody tree or shrub, including branching, stem behavior, dormancy, internodes, and overall habit. Growth traits help separate compact, upright, lanky, spreading, and vigorous cultivars.
What to look for: Observe the whole plant over time, not just one branch. Note branching pattern, tip growth, seasonal leaf drop, container behavior, bloom habit, and whether the plant stays compact or becomes large and open.
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.
