So I’ve planted the red geraniums. I hope they’ll grow into a little hedge that spreads across the weed mats, where mulch will soon replace those old rocks and bricks. But now I can’t find the article that told me that bees avoid red geraniums. And why. I can confirm that bees see and distinguish all colours except red so they won’t see them. But that might mean that the bees will just fly straight past and into the spray zone. The geraniums won’t be a barrier. Is there another factor? The geranium scent perhaps?
Or the multiple petals? One reason to use heritage seeds is because new and hybrid flower varieties with double or triple flowers and new colours tend to produce less pollen and less nectar. Bees sense this. (And some heavily petalled old varieties, like peonies, are also unattractive to bees.)
And, in a related issue, how come the bumbles are right into our red poppies at the mo? I watch this wild piece of garden regularly and have yet to see a bee land on the calendula (yellow) or daisy (white with yellow centre) or cornflower (blue). But they visit every red poppy that blooms.
Susan Brackney’s Plan Bee explains that – unlike human beans (I’m reading Roald Dahl’s The BFG) – bees see ultra violet light. They rely on the location of the sun to help them navigate and they find their way on cloudy days because ultra violet rays penetrate clouds. And red poppies reflect ultra violet especially well. If we could see ultra violet light, we’d see red poppies shimmer in the sun and extra streaks and lines like airport landing strips, which show the way to the nectar.
I’m disappointed that there are few bees in the garden over this mid-summer time and that they are all bumbles. Not a honey bee in sight. And the only flowers they seem interested in are the borage – white and blue – and the lavender.
It’s especially disappointing because at last some of my new bee-loved flowers are in flower and so far the bees just whizz past them en route to the lavender and borage. They’re phacelia (purple tansy). Most of the seedlings died, so there aren’t many mature plants.
The alyssum doesn’t attract the bees either.
Nor the cornflowers. Though I did see one on this yellow flowering rocket (there for seed), in among the cornflowers. Briefly.
I’m following the action closely. Hoping to learn more.
And if you know anything about these little mysteries that intrigue me, I’d love to hear from you.
