The Green Velvet Alocasia (Alocasia micholitziana 'Frydek') is another Alocasia that is growing in popularity because of its attractive, arrow-shaped dark green foliage and distinctive contrasting color veins. However, unlike the silvery veins of Black Velvet, Alocasia frydek has white veins, and it grows faster and larger, reaching heights of up to 3 feet.
