Purple Knight (Alternanthera dentata) : This dark-leaved, tropical foliage plant loves heat, and is useful spreading through a bed, border, or in a container where its deep purple leaves can contrast with brightly colored flowers or foliage.
Light: It can survive in full light as well as semi shade.
Soil: Fertile loamy soil with good drainage.
Watering: Likes to be watered everyday.
Feeding: Any organic manure or mild NPK every week is good for shining leaves.
Repotting: This is needed if the plant has outgrown its pot. It's a good idea to repot in Spring.
Tips: Purple-ruby foliage that is almost black. Performs well in high heat, where its color deepens and becomes richer.
