Ludwigia Repens 'Rubin'

Ludwigia repens 'Rubin' is a deep red form of the well-known Ludwigia repens obtained through selection. While the upper side of the leaf stays green-copper in the wild species, in 'Rubin' both sides are a wine-red tone. It is as hardy as the parent species; it also grows in an aquarium without CO₂, only its color turns a little brownish. It creates a strong color contrast among green-leaved background plants.

• The stems are separated one by one, the lower leaf pairs are pinched off and they are buried 3–4 cm deep.
• Leave 2–3 cm between stems; plant in clusters of 5–7 stems.
• It is placed in the background or midground, in an area that gets good light.

• Light: Medium; the darkest color is seen in strong light.
• CO₂: Not required, but beneficial for color and growth.
• Fertilizer: Iron-rich liquid fertilizer supports the red tone; root tabs are also beneficial.
• Trimming: Stems approaching the surface are cut from the top; the cut tops can be replanted.
