Description

Lobelia cardinalis grows wild in Northern America. In the nursery this plant is cultivated in marshy conditions, forming dark-green leaves which are purple underneath. In aquariums the leaves turn a beautiful shade of light-green, with stems 10-30 cm tall and 5-10 cm wide.

Widely used in Dutch aquariums in so-called “plant streets”. In open aquariums it grows above the water surface, where it forms very beautiful scarlet flowers and the leaves regain their colour. Can be used in garden ponds.
