Lobelia
The plants in this genus, native to tropical regions, are either terrestrial
or paludal. One of the latter types can adjust to tropical aquariums, although it
grows very slowly.
Lobelia cardinalis
This amphibious plant can resist temperatures of 10-20°C in moderately hard,
approximately neutral water. The cardinal flower is appropriate for temperate or
tropical aquariums, though it requires intense light in a tropical tank. It multiplies
by means of cuttings. Size: 30 cm.
