Water Hedge

Geographical Origin and Habitat: Native to the eastern United States, where it grows submerged or emersed in shallow ponds and river banks.

Taxonomy & Genetics: Also known as Didiplis diandra or Peplis diandra. Belongs to the Lythraceae family.

Physical Structure: Thin erect stem bearing fine decussate needle-like leaves arranged in crossing pairs. Forms compact, dense bushes.

Color & Texture: Under low light it remains bright green, but under intense light the leaf tips display stunning orange, red, or yellow hues.

Lighting & CO2: Requires high-intensity lighting to achieve its orange-red coloration. CO2 injection is highly recommended to prevent leggy growth.

Nutrition & Substrate: Demands a nutrient-rich substrate and regular dosing of micronutrients, particularly iron. Pale tips indicate iron deficiency.

Water Chemistry: Prefers soft to medium-hard water, with pH between 5.5 and 7.5. Keep temperature stable between 20°C and 28°C.

Space Management & Placement: Best suited for the midground or background. Plant stems with spacing to prevent bottom rot from shading.

Pruning: Prune regularly by trimming the top shoots. This encourages lateral branching and helps maintain its compact, hedge-like shape.

Risks & Diseases: Highly sensitive to iron deficiencies. Can rot at the base if shaded by other plants or if planted too close together.
