Plant Comparison

Alocasia Scalprum vs Portodora

Scalprum and Portodora sit at opposite ends of the Alocasia size range. Scalprum is small, with stiff, narrow, blade-shaped leaves that look almost weapon-like. Portodora is one of the largest Alocasias grown, with enormous wavy-edged leaves on a plant that can reach ceiling height outdoors. If you are choosing based on the space you actually have, this comparison answers itself quickly.
