This is Asclepias tuberosa in my wild garden.  We planted it about 5 years ago.  That was before we extended the deer fence.  They ate it all, I thought.  But it has come back.  And it's spreading!  Yay!!!!

 

Also called butterfly weed, it attracts Monarch butterflies.  They lay their eggs on the undersides of the leaves, and the caterpillars eat the leaves until they're ready to cocoon.  Then we get a whole new generation of Monarchs.  You can see butterfly weed down in the meadow too, orange flowers this time of year.  Look for patches of orange in your travels.  It might just be butterfly weed, waiting for Monarchs.
 

Glad to support all the butterfly populations.  

 

HAPPY GARDENING!!!
