Otherwise known as the ‘Red Star Ludwigia’, L. peruensis is a unique Ludwigia with deep red, lanceolate-shaped leaves. Each leaf ends in a sharp point, giving the plant a star-like appearance. Unlike many other Ludwigia species, L. peruensis does not produce side stems. It is an amphibious stem plant that will grow vertically and can extend beyond the surface of the water if left untended. The substantial height and striking foliage make this plant a perfect midground or background accent, especially when set against a landscape of green.
L. peruensis is one of the more difficult Ludwigia species to cultivate. The leaves and stems will begin to dissolve under weak lighting or when planted in a nutrient deficient substrate. Flimsy growth and loss of colour may indicate that the lighting is not powerful enough, as L. peruensis will require 3 to 5 watts per gallon of full spectrum light for optimal growth. CO2 supplementation is also necessary; it will promote healthy growth, although L. peruensis tends to grow slowly, even when thriving. Regular additions of iron-rich fertilizers and trace elements should help to speed things up. Any cuttings can be replanted in the substrate.
