Blue Wild Indigo is a large, bushy perennial, growing about 4 feet tall and with beautiful and eye-catching deep blue summer flowers on tough stems.  
 
     After the blooms come the puffy seed pods that emerge green and turn a dark gray by fall. These pods persist well into winter.
 
     This Perennial Plant Association 2010 Perennial of the Year looks lovely in a meadow and is stunning paired with other sun-lovers like Butterfly Milkweed, Purple Coneflower and Black-eyed Susan. 
 
     Butterflies, bees and other pollinators love Wild Indigo, which also is one of the few larval hosts for the Wild Indigo Duskywing.
 
     Wild Blue Indigo spends its first two or three seasons establishing underground, but by the third season and thereafter the blooms and foliage flourish.  Blue Indigo is not a good transplant candidate because of its taproot.
 
     Fun fact: Children once used the seed pods as rattles.
