Blade

Environmental condition

Definition: The flat portion of the grass leaf above the sheath. Also the flattened, green portion of a leaf.

How it applies to plumeria: Blade describes a growing condition that can change how a plumeria looks or performs. Sun, heat, cool weather, humidity, and season can affect color intensity, fading, leaf condition, and blooming behavior.

What to look for: Record region, season, sun exposure, temperature range, and time of day when comparing photos or traits. The same cultivar can look different under different growing conditions.

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.
