You Can Stay

The plants in my garden must now be useful to native insects or very beloved by me.  All others will be taken out.
Because of my new-found interest in bees, I watch to see which plants the bees like.  The aster pictured here is/was Alma Potschke -- a vivid magenta hybrid of New England aster.  Last year it began to revert to its native stock -- a purple aster.  Today I noticed that the bees were constant around the purple flowers but none were attracted to the magenta ones.  Another bit of proof that bees prefer native rather than hybridized plants.
The aster can stay because of its reverted parts.  Next year, I will cut out any magenta stems and let the plant go completely back to its purple origin.
