Parsley

Whilst most gardeners will at one time or another planted parsley for use as a herb, few look upon it as a vastly under used foliage plant with serious ornamental potential.

It provides a soft, billowy, bright-green contrast in pots, for example, with things like bright-red pelargonium - a plant frequently mis-describes as geraniums, for reasons that have never been clear to me because geraniums are a completely different plant.

You can often purchase fresh parsley plant from your local supermarket that are every bit as good as what you will buy from garden centres and usually much cheaper.
