ASCLEPIAS tuberosa

In a gardening class I learned to call a plant by its Latin name, instead of its
common name; because, there can be many common names, which can be confusing.
  
This plant is a good example.  Here are some of the common names:
-Indian Root
-Indian Posy
-Canada Root 
-Pleurisy Root
-Chigger Flower
-Silky Swallow-wort (my favorite)
-Butterfly Milkweed:  most common name

This is one of 200 species in this family of native American perennial herbs..They are best know for being a host plant for Monarch Butterflies; & are attractive to other pollinators.  This is why I planted it in my little side
flower bed:  I was hoping the color & abundant nectar would attract the Monarchs.  They are also a food source for the Queen butterflies &
Emperor butterfly larvae.

That's the good news.  The bad news is:  it is invasive, has an extensive root system & produces lots of seeds.  It is also highly toxic to dogs & horses.  Mine are planted in a confined area, with a fence around the flower bed. The area is not of much interest to Angus, who is a strict Keto carnivore.  

The flower's symbolism:  Remembrance, Dignity & Freedom

"The gentian's bluest fringes
Are curling in the sun
In dusty pods the milkweed
Its hidden silk has spun."
-Helen Hunt Jackson
