This is another species of Asclepias. It is Asclepias variegata, also known as Redring or White Milkweed.  It is native to eastern North America, and can be found in Canada and the US.  We've seen it a lot in our travels on the Skyline Drive in Virginia, and right here in western North Carolina.  They're easy to spot on roadways and in the meadows, especially when they're blooming.  Just like other milkweeds, it is also food for Monarch butterflies.  
 

This one stands about 2 feet tall, and lives at Meeks Park.  We go there a lot.  There is a 2 mile walking path with gentle hills, (not like our neighborhood walk with its 600 foot vertical climb.)  And there is always something interesting to see.  
 

The genus was formally described by Carl Linnaeus in 1753, who named it after Asclepius, the Greek god of healing.  I just looked this up, and found that I've been spelling the plant genus name incorrectly.  The Greek god's name is Asclepius, and the plant genus name is Asclepias.  I'll go back and revise my writings, because it matters to me that if I'm teaching you something, I should have my facts straight.  
 

I hope you see some milkweed blooming;  it means there will be food for the Monarch butterflies.

 

HAPPY GARDENING!!!
