About 6ft. tall. But that may be through being in the shade a lot.
Has approx. 3" long leaves without stems which grow straight from the only stem on the plant in a trio every few inches, and the top 5 trio's, have long stemmed flower buds growing from above each leaf.
It self seeded in a pot next to the bird feeders about July/August so it may be from my wild bird food. As you can see the flower has 9 petals.
