Here's the plant I got from Jeff in the first three pictures. Notice how the new growth comes out with a red midvein. Also look at the size of the mature leaves. All of them are well over a foot long, not including the petiole. Next are two shots of Pride of Winter Haven. The midvein starts out white and eventually becomes red. The leaves are rarely over 10" long. Both of them get a few hours of direct sun, the first one in the late afternoon - setting sun, and the other midday, but only at this time of the year. The unknown is in shade most of the day. Dappled sun for a few hours at midday, which may account for the size of the leaves but not the prominent red midvein.
