Tray of very young outdoor plants (L1 Liverpool City Centre)

This is a tray with plants that just have come out in my garden. There are very young trees: 1 plum (prunus domestica), 1 sycamore (Acer pseudoplatanus), 3x goat willow (salix Cabra), 1x California blackberry (rubus ursinus), some of them under planted with yellow poppy, violet and lavender.
Would suit someone with a lot of space and patience as these are very small at the moment, but have the potential to grow very big.
