I've had this plant for five years, bought originally from Lowe's. It is quite a showy plant with large, medium green leaves, multiple tall stalks reaching 10-12' high, and from mid-summer through frost it has lots of beautiful, vibrant fucshia blooms that are easily 5-7" in diameter with bright yellow/gold stamens and pistil in the center.

My friend saw this bush...she cut some finger-thick brances off and put them in a pail of water....when they sprouted roots we put them in potting soil in pots....they have done well...the ones I put in the ground are approx 4 ft tall....I have seen two others at different places that were 15-20 ft tall and beautiful when covered with pink blooms...too bad it is in October and not in the spring....can be cut back drastically....very large leaves with several points....would not make a good privacy screen as they lose their leaves in the winter but make a great shade screen for my outbuilding in the Texas summer
