Need help identifying a tropical shrub
I originally purchased the shrub at Home Depot. It has small heart shaped dark green leaves on thin, dark brown stems - flowers are upright bell shaped - blue/purple with a yellow throat. Since I've moved, I can not find another shrub like this or even know the name. It was very pretty. About 3' tall bushy to about 3' as well. It grew well in light shade and was perenial. Can anyone help? I'd really appreciate it.
