Ludwigia Cuba
Ludwigia inclinata var. verticillata 'Cuba'
Plantae›Tracheophyta›Magnoliopsida›Myrtales›Onagraceae
📍 South America
One of the most striking red-orange stem plants. Whorled leaf arrangement creates a unique spiral pattern. Demanding but spectacular.
Tank Mates
Shrimp will not damage plant tissue and help control algae on leaves
Excellent algae control without harming delicate new growth
Small, peaceful algae eaters that won't uproot or damage stem plants
Complementary high-light stem plant with similar care requirements
Low-light companion plant that creates visual contrast in background plantings
Small, peaceful fish that won't uproot plants or cause damage
Common Diseases
Nutrient Deficiency (Iron/Magnesium)
Yellowing of new leaves while veins remain green; stunted growth; pale coloration
Increase liquid fertilizer dosing, particularly micronutrient trace elements containing iron and magnesium. Ensure CO2 levels are adequate (30-40 ppm) to support nutrient uptake
Algae Overgrowth
Green or brown algae coating leaves; reduced light penetration; plant appears smothered
Increase water changes to 30-50% weekly, reduce photoperiod to 8-10 hours, add algae-eating shrimp or fish, and manually remove affected leaves. Ensure CO2 and nutrient balance to outcompete algae
Melting (Tissue Decay)
Leaves become translucent, mushy, and dissolve; stems become soft and collapse
Improve water quality with frequent partial water changes, ensure adequate CO2 injection, increase lighting intensity, and remove severely affected stems. This often occurs during acclimation to new tank conditions
Slow/Stunted Growth
Minimal new leaf development; plant appears dormant; leaves remain small
Verify CO2 levels are 30-40 ppm, increase light intensity to 60+ PAR, dose all-in-one fertilizer 2-3 times weekly, and ensure water temperature is 24-28°C for optimal metabolic activity
