Its an over rated plant.

Blue Tango is a beautiful but large plant and very cold tender. I'v killed two of them. Won't try it again. If you get one don't let it get a hint of cold.

No 'Blue Tango', but I have 'Del Mar' which does fine here in San Diego outside in the garden. Beautiful when in bloom; not so interesting out of bloom.

I have both, both do well in S FL. They look very similar, but Blue Tango is much larger. They both bloom for months.
