Corolla
Flower trait
Definition: The inner perianth of a flower. The corolla typically surrounds the reproductive parts of the flower. It may be continuous as in a petunia, lobed, or divided into distinct petals.
How it applies to plumeria: Corolla can describe the bloom, inflorescence, fragrance, or flower structure of a plumeria. Flower traits are some of the most useful comparison clues, especially when they are recorded with bloom age, season, sun exposure, and location.
What to look for: Compare mature blooms from several photos when possible. Note the center color, petal shape, petal overlap, color pattern, fragrance, bloom size, and whether the color fades, intensifies, or changes with heat and sun.
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.
