Butterfly weed. Whether it is asclepias currassavica or asclepia tuberosa it is beautiful. From what I can tell, asclepia tuberosa is a native, hardy perennial to North America while from the same family, asclepia currassavica is a native to South America. One website said it is originally a native to South America, but now considered native to Texas.
While doing some internet research I found several other common names that this beauty is also known: Bloodflower Butterfly Weed, Orange Milkweed, Showy Mexican Milkweed, Swallow-wort, Scarlet Milkweed.
Hardiness Zones: USDA Zone 7 to USDA Zone 10
Height: Grows 30-36” tall. Space 30-36” apart.
Exposure: Plant in Full Sun.
Bloom Time: Blooms mid-spring to late fall.
Water Requirements: Water 2-3 times per week until established.

Butterfly Weed is also a larval host plant for the Monarch Butterfly.
I started my butterfly weed from seeds earlier this spring and then transplanted it in an area that is shaded in the morning and then get full afternoon sun. I will mention that I needed to water it ever other day for several months and then I was able to cut back to watering every three days. Towards the end of September I was able to cut back on the water again as our nighttime temps were dropping into the high 70’s.
It started to bloom 29 Sept and my three stalks are 24″ tall. Not bad for a terribly hot summer without any rain at all. I will collect seeds and add more of this beautiful plant to my gardens in the spring. I have also noticed there are new shoots coming up at the base of two of my stalks. That is a good sign. I think it is happy out there in my garden. I know I am certainly happy to have it growing out there.
