Cue forward a little while and I came across a small, weedy plant in a Pound Shop. It was fainting from lack of water, and it didn't look very healthy, but when I examined the packet I saw that it was labelled Amelanchier - the only one on the whole stand, among the more commonplace trees and shrubs. So I decided it was well worth risking my pound on, took it home, nurtured it a bit and finally thought I could risk planting it out in the garden.
That was some four or five years ago, and just look at it now! It is probably the most beautiful thing in the garden - delicate, elegantly shaped and with gorgeous, fine blossoms. A pound well spent.
That's what gardening is all about for me. Not paying a fortune for high concept designs and expensive plants, but looking for wonderful finds in unexpected places and bringing out the best in them. Not a bad motto for life and maybe for writing too!
Meanwhile, you could do worse than explore the Pound Shops, and other bargain shops, which all tend to have stands of inexpensive shrubs, trees and other plants outside at this time of the year. But even in your local garden centre, there are amazing bargains to be found languishing in some sad corner: plants that may seem to be past their best, but only need food and water and dead-heading; plants that are just out of season, but will be wonderful if you can wait for next year; trays of annuals that are root bound and have dried out a bit and need potting on. All of them tend to be sold off at bargain prices, so if you're working to a budget but still want a nice garden, use your imagination and do a bit of rescue and rehoming. The plants will thank you for it.
