About 6 yrs ago I got 3 clems at Home Depot that were mis-labeled. I ID'd one, but the other 2 plants that are alike, and most definitely *not* MultiBlue, escape me. For a long time I assuemd they were jackmanii, as it is so common here, After a close look yesterday at the huge flower size and the beautiful anthers, I am wondering if they could be Polsh Spirit.
The plant grows very tall here, does not bloom untill later in summer than others like Niobe and Etoile Rose and has the most beautiful red/purple tipped anthers.
What do you think guys??

Here is a wide shot
