Oh-that is different-not what I was expecting
Those are no-way big enough to plant out-not much more than seedlings-the best thing you can do is just let them grow and next Autumn they should be big enough to plant out for flowering in Spring 2014
I know that seems a long way-of but at that size I cannot see you getting a big enough plant for flowering in Spring 2013
Seed is usually sown are around April/May to get plants for setting out in the Autumn or big plants are sold in September
Sorry but think you are in for a bit of a wait
All this assumes they are the biennial wall flower -not the perennial type?
Can you remember what your bought?
