I have a large container of Tradescantia pallida and just discovered I don't have a photo of mine
. However, there is a variety of pallida called 'Purple Queen' and all the pallidas have red foliage (I think). The database here doesn't have a photo of 'Purple Queen', but I would expect it would be very similar to the other pallidas. This is one from the database. Is yours going to be similar? There are a lot of other photos of this one and others in the database.
