I used a packet of wildflower seed, although most of what came up was the pretty yellow Corn Marigold, which used to be a ubiquitous weed of cornfields before industrial farming did for it (and many other once common but now rare and endangered wild flowers).
Anyway it has spread its grey-green foliage and bright yellow flowers around enthusiastically, almost as though it can't quite believe no one has come along in a tractor and sprayed it from a great height with Glyphosate, and in company with some red field poppies, the odd bright blue cornflower and a bit of white chamomile has made a tiny "natural" patchwork of the kind you would never ordinarily plant in your border, but which has a charm all of its own. It's also good for the bees, which is always a consideration in my garden. So I've been collecting the seed from the very many seedheads, and am hoping to expand the planting area next summer into a Monet-esque cornfield ( what do you mean ambitious..?) but without the corn of course. Come to think of it, the corn might actually come in handy for the chickens...Hmm.. Anyway it's a sloping area under trees which currently supports a good display of daffodils in the spring, but not much else, so I'm hoping this plan will fit in with the early bulbs and provide a continuity of flowers through the summer and autumn.
