A quick visual split of three common leaf forms used in succulent ID.
Rosettes
Echeveria elegans forms flat, symmetrical rosettes often with farina; Haworthiopsis fasciata stands upright with zebra bands; Aeonium arboreum grows rosettes on woody stems that can branch like bouquets.
Paddles
Kalanchoe luciae bears broad, flat leaves that can blush red at the margins under bright light and cool nights.
Beadlike
Sedum rubrotinctum has bean-shaped leaves that color up bronze-red with sun and drought.
