Geranium

Pelargonium, P. x hybridum

Category: Flowers

Geraniums are recognizable for their vibrant colored, umbrel blooms and curvy, fragrant leaves. Geraniums are terrific in containers and as bedding plants in borders and paths. Perennial geraniums (cranesbill, wild geranium) are in the genus geranium (x sanguineum, x carolinianum, x maculatum, etc), not to be confused with the familiar annual geranium.
