Beautiful plant that grows to a few inches tall, and up along its stem it’ll shoot roots out. You’re able to cut the stem, and plant the rooted parts to keep it propagating. When the plant is grown out of water, it’ll exhibit red leaves, and even a red flower. I’ve only grown it under water, but it’s a great low plant that bushes up when exposed to more light. The cardinal plant is also very popular in dutch aquascaping because of its height fitting great as a mid-ground plant.
