Little things come in big packages

Waiting on my doorstep when I got back from shopping was a rectangular cardboard box, almost as tall as a pillar box.
This was inside, with some bulbs - eryngium yuccifolium or Rattlesnake Master, a North American prairie flower. I've seen how attractive other types of eryngium are to bees, fingers crossed these tiny flowerheads will be featuring in bumblesnaps in due course.
