I can't get decent rigid seed trays here, and so I've started using polystyrene fish boxes from our friendly local supermarket. They are a good substitute and last several seasons. I planted out fish boxes full of Nepeta nervosa, Nepeta subsessilis, Salvia x superba, Asphodeline lutea, Stipa gigantea, Festuca amythestina, all from spring 2012 sowings. Along the edge of what will be the wilder side of the winter garden, where I can keep my eye on them, I've planted a few cultivars that are more special and of which I could only afford to buy one small plant: Aster x frikartii 'Monch', Helenium autumnale 'Moerheim Beauty', Epimedium x versicolor 'Sulphureum'. These, like the yellow Banksian rose, are all are old friends from previous gardens that I'm delighted to finally grow again. There was also a grass addition, new to me although I've always been fond of Miscanthus - M. sinensis 'Morning Light' looks to be a wonderfully soft, silvery addition.
Below are pictures of what the border looked like when I'd finished (not much different, to be honest, but it was wonderful to get the little souls out of their various pots and fish boxes!)
