Ludwigia repens ‘Rubin’

This strikingly-coloured dark red plant was imported by the Danish aquatic plant nursery Tropica under the name Ludwigia repens ‘Rubin’. It is also known as Ludwigia sp. “wine red”. Recent research showed that it is not a L. repens variety but a relative of L. glandulosa, and probably a hybrid. For this reason, it is also called Ludwigia aff. glandulosa (Kramer 2006; aff. = affinis = “related, close”) or Ludwigia “Rubin” (Kasselmann 2010). Some nurseries erroneously carry the plant as L. glandulosa or “L. glandiosa” (distrinction from true L. glandulosa: see below).

The leaf form of Ludwigia “Rubin” is quite similar to that of L. repens, and its growth habit is also comparable. However, whereas L. repens always has oppsite leaves (2 leaves per node), the shoot parts of L. “Rubin” have opposite as well as alternate leaves (1 leaf per node) at irregular intervals.
