One of the plants Cathy bought on our annual Mother’s Day trip to the nursery (a week early this year) was this blood flower, Asclepias curassavica ‘Silky Red’. As you can see, the colors are pretty intense. This species of butterfly weed is native to the Caribbean and Central and South America and is only winter hardy to USDA zones 9 to 11, so we grow it as an annual here but it’s worth it. The butterflies and other insects love it and even without that, it’s just a beautiful flower. If you have a very bright indoor location (or a heated greenhouse!) then you could bring it in for the winter, but we just start new each year.
