I'm having a go at doing this, although I don't have much of a clue.
What I've done so far are pots with spring bulbs, white geraniums and I've just put in some trailing lobelia and sweet peas.
Anyone got tips to share?
And, by the by, does anyone know why I haven't found any pansy or viola plants this year? We were away until the end of May, but surely it's not too late?
