Ludwigia Glandulosa

Ludwigia glandulosa is a ludwigia with elongated, lance-shaped leaves from the swamps of the southeastern United States. In strong light the leaves deepen from dark red to purple-burgundy, and the plant becomes one of the darkest-colored stem plants in the aquarium. It grows more slowly than other ludwigias, which makes it a color focal point that does not need frequent trimming. In the trade it is often sold as 'Peruensis'. It survives in medium light, but its color turns brownish green.

• Stems are planted singly or in twos or threes, 3 cm apart and 3–4 cm deep.
• In the midground or background it creates a strong color contrast in front of or next to light green plants.
• Choose a spot that light reaches directly.

• Light: High; the dark color only develops in strong light.
• CO₂: Not required, but beneficial.
• Fertilizer: Iron and potassium supplementation; root tabs support growth.
• Trimming: Because it grows slowly, it is rarely needed; tops cut from the top are replanted.
