And this is why Buddleia davidii is called Butterfly Bush.  See the Tiger swallowtail?  

 

Butterflies and moths love this bush because there are lots of tiny flowers all in one place.  There are long trusses of blooms on new growth, and some grow up to a foot long!  That is a lot of nectar in one spot.  

 

Be on the lookout for Butterfly bushes in your neighborhood;  maybe you'll get to see the butterflies enjoying them.  

 

 

HAPPY GARDENING!!!
