Alternanthera cardinalis is a striking red-purple aquarium stem plant that adds strong contrast to planted tanks. It is a popular choice when you want to break up green layouts and introduce more depth, colour and visual impact.
Best used in the midground or background, this plant can reach up to 50 cm in height and works especially well

Nope
It just died very very quickly.
Had a fluval aquasky light on full nit 6 inches from the tip, tropica root tabs, tropica liquid ferts including Seachem Iron but it was either emerged grown and was converting hard or really does need C02. It never came back and description said C02 was not required. Just wont grow for me.
