Well after you ask for a photo I was suprised to find so many and I remember the silky stuff that blows in the wind not the flower. Link below to many kinds http://www.monarchwatch.org/milkweed/guide/index.htm the structure http://www.monarchwatch.org/milkweed/index.htm
All info is from a monarch site as you can tell and if you want the butterflys this seems to work. Now I did find one with the silky stuff I loved to play with as a kid. http://www.all-creatures.org/pics/wfshl-milkweed.html Thanks Fritz for asking a question as I learned so much more! Quinta
