RE: Finding purple in the wild

On purple and bees:

Bees are unusually sensitive to colours in the blue-to-ultraviolet range, and many flowers that appear purple to humans are especially attractive to them because those flowers often reflect ultraviolet patterns that act like landing guides pointing toward nectar. Humans can’t naturally see ultraviolet light, but bees can, so a flower that looks like a simple lavender bloom to us may appear to a bee as a highly contrasted target with glowing pathways and markers. A lot of bee-pollinated flowers evolved shades of purple, violet, and blue partly because bees detect those colours very efficiently against green foliage, making the flowers easier to find from a distance. Interestingly, bees don’t perceive colour the same way humans do at all: they can’t really see red well, but they are excellent at distinguishing ultraviolet, blue, and green wavelengths. This is why many garden plants marketed as “bee friendly” lean heavily into purple tones — things like lavender, salvia, catmint, and rosemary tend to attract large numbers of pollinators. There’s also evidence that bees can learn and remember colour associations remarkably well, meaning if a purple flower consistently rewards them with nectar, they’ll preferentially revisit similar colours in future foraging trips.

Thanks Chatty. I pulled that up because I'd read something in a book a while back about bees and particularly purple, but also why we usually have purple and yellows in meadows - it's nature's way of saying 'come get us, bees'.
