As I was looking over a whole range of the colorful flowers yesterday at Green Spring Gardens, I gradually realized that I was drawn most to those with simple shapes and relatively subdued colors, like the modest spiderwort (g. Tradescantia). There is a real beauty in its simplicity.
The bees seemed to like the spiderworts too, including one that I photographed with overfilled pollen sacs.

Spiderworts are so nice. It’s one of the first wildflowers I learned to identify, and I’ve remained quite fond of it. Are those two little yellow thingies that look like boxing gloves the pollen sacs? I’m guessing so — they look like saddlebags.
Yes, as far as I can tell, those are pollen sacs. The bees gather the pollen into these sacs on their legs and carry it back to their hive (usually they don’t gather quite so much before they go to empty the sac.)
I have this in my garden. It is a perfect flower for me with the purple petals and bright yellow stamens and of course it attracts all sorts of bees. Amelia
I noted a wider variation in coloration while looking for a flower to shoot, with lots of different shades of blue and purple.
Beautiful, mine are all the same tone of purple.
Spiderwort is one of the flowers I’ve known the longest and I like its simplicity as well.
I’ve never seen a bee with so much pollen!
