Dear Bonaventure,

    I agree completely with Julius. When the first leaf appear, check on the 
petioles. If they are light green, you have X. sagittifolium. If they are 
"dark", it can be either X. atrovirens or X. violaceum. In fact, their names 
never lie: X. violaceum is purple and X. atrovirens is blackish green. 
However, the thick layer of wax on the petioles of both species may confuse 
your sense of purplish... Both will appear purplish for a non-trained eye. 
So check on the nerves below at the leaves. If they are really purplish, it 
is X. violaceum. If they are medium green or dark green, you are a proud 
owner of a X. atrovirens! If they are lavender with green spots and yellow 
strips, just scream... You have something from outer space growing in your 
pot! "Take me to your leader"

                                   Best wishes, ;o)
