Limited Edition - Helanthium 'Vesuvius'Helanthium 'Vesuvius' (previously called Echinodorus 'Vesuvius') is a cultured species based on Helanthium angustifolia from Oriental Aquarium Plants. The narrow and twisted green leaves makes it an unusual addition to the Helanthium family. The rosette species grows vigorously with many medium length and narrow leaves (10 20 cm tall), and is highly decorative as a solitary plant (rosette 10 15 cm wide). 'Vesuvius' spreads readily with runners.
