>> her husband was always complaining when she planted flowers that you couldn't eat them. Her reply was, "But they feed my soul!"
Bees eat the nectar and spread the pollen. For a lot of crops: no bees, no fruit!
P.S. In the PNW, slugs seemed to like Delphinium seedlings better than anything else. I had to get them pretty big before I set them out, or the slugs would mow them right down to the soil surface overnight.
Now I use beer saucers and slug bait regularly.
But once my Delph got big, they avoided it completely !
