Lobelia cardinalis is a North American native plant used in aquariums for its vibrant green, circular leaves that can have reddish-purple undersides, and its striking scarlet red flowers when grown emersed. It is a versatile plant that can be used in the foreground or midground and grows in a rosette or stem-like form, with smaller-leaved varieties available for a more compact growth. While it grows best with supplemental CO2 and good lighting, it can be easily maintained in a low-tech tank. Listed with ExportYourStore.com
