Helanthium augustifolia 'Vesuvius' used to be known as an Echinodorus sword, but has been reclassified. It is also known as a 'Corkscrew Chain Sword' Vesuvius is a smaller, bright green sword, with thin leaves growing in an undulating manner; very much like an erupting volcano! An easy to care for sword, Vesuvius propagates readily by sending out runners. Very easy-to-keep plant that needs neither Co2 or high lights to thrive. This version is larger and more mature than the bare-root versions, and is potted in rockwool with slow-release fertilizer. Potted variety is well- rooted between 4-6" tall. Grown EMERGENT Growing requirements: 65-80 Degrees Fahrenheit Ph 6-8 Low to Medium light intensity Moderate growth speed As I like to keep real ecosystems in my aquariums, there's always the possibility of harmless snail or dwarf shrimp hitchhikers!
