If you know there is a particular wild-growing plant that is identifiable only by flowers but still otherwise distinct enough from the surrounding vegetation, it might help to photograph the plant with its flowers in season, and photograph the same plant when out of season. This may help to build up a overall picture/data set of the plant species when it’s not in flower!
For example, I’ve personally photographed an individual plant in and out of season: https://www.inaturalist.org/observations/71008830
