Echinodorus cordifolius 'Spade Leaf'

Echinodorus cordifolius 'Spade Leaf' is a selected form of the Spade Leaf or Radicans Sword, native to North and Central America from Mexico through the southeastern United States. It is distinguished by large, clearly heart-shaped submerged leaves with strongly defined midribs and lateral veins that give the foliage a ribbed, sculptural quality. The plant forms a large rosette reaching 30–55 cm with a bold, structured presence ideal for spacious background planting.

Like the species, 'Spade Leaf' is tolerant of a wide temperature range including cooler subtropical conditions, adapting to both soft and moderately hard water. It is an aggressive root feeder and will deplete nutrient-poor substrates quickly; consistent fertilisation is key to maintaining the quality of new leaf growth.

This variant is particularly well suited to North American or Central American biotope aquariums, where its native-range origin adds authenticity to the layout. It can also be grown paludarium-style, eventually sending up emersed leaves and white flowers above the waterline.
