In Ontario, tomatoes are ripe for picking in late June and early July. Wild bees such as mud bees and the yellow-faced bumblebees frequently gravitate towards this yellow flower in its early bloom and continue pollinating it through until a rather large, juicy tomato appears ready to pick and serve. This picture, in Northern California (care of Lisa Gregor), shows the plant in its early pollinating stage. You can see the small green bulbs starting to appear. We have our Bumblebees to thank for our flourishing, locally grown tomatoes.
