Default

they are not the same. ludwigia red has been labeled here as rubin

rubin has a more elongated leaf than sp. red. rubin also turns green and survives with less light

ludwigia sp.red with low enough light to change color will basically wither away and die
if its light requirements are met it will be orange, red, or purplish with enough light orange being the lower light levels
