Justina Davis is unique in that it is an all-green Venus flytrap, which is rare for a Venus flytrap. It will not develop any red coloration. It is a nice upright grower, with slender stalks and fully-functioning menacing traps!
'Justina Davis' is an officially registered Venus Flytrap cultivar. There are very few all-green Venus Flytraps, with no red coloration at all on the petioles nor inside the traps. The Justina Davis cultivar name was created for such an all-green plant.
