This lovely woodland aster-family member blooms late, often into November.
 
     It spreads by rhizomes and readily self seeds, creating a beautiful flurry of white flowers perhaps along a woodland edge or near a pond.  It's a great plant for filling in large areas.   
 
     Bonus: it tends to settle down once established and grows well among other plants.
 
     A beautiful plant for wildlife, butterflies, beetles and moths drink the nectar, and caterpillars eat the leaves.
 
     All parts of this plant are toxic to mammals.  Abraham Lincoln's mother is believed to have died after drinking milk from a cow exposed to White Snakeroot.
 
     Fun fact: Early settlers used it to treat snakebite.
