Bits from the Rennie's Garden

Any idea what this is? We bought it from the centre and it is very healthy, not to say beautiful, but I have no idea what it is as I seem to have lost the label.

Mary's favourite flowers, wallflowers. I don't see why they are so special but Mary and her mother both agree on their place way up on the favourite plant list.

A small shrub I thought was a cherry. Flowers come out before leaves and last longer than cherry blossom. What should I put on the label?
