I see the Verbena hastata and the V. hastata alba, but I also have the pink variety. Is there a specific name for that one? It comes true in my garden, althoug I also have the purple and white one.
Perhaps we need to ask that the caption of the photos note the botanical name (with variety or form) and they all be placed in the V. hastata entry with appropriate synonyms noted.
Verbena hastata, like many species of wild plants that typically have blue or blue-violet flowers, will often produce pink- or white-flowered individuals within a population. There is no reason why pictures of the pink- or white-flowered versions can't be entered in the existing Verbena hastata entry: Blue Vervain (Verbena hastata)
