I was mowing the lawn a little carelessly on a warm sunny day and I kept bumping into herbs that had been planted at the fronts of the borders. The plan being to have some low edging against the lawn. The most beautiful scents started wafting around me and it made the chore of mowing into a pleasure. So what herbs had been used? Well lots of lavender, mint, sage, thyme, in fact any low growing herbs will do.
Edging paths with herbs works in the same way, especially if you can't walk in a straight line (enough said). The low growing Thymus Serphyllum is also rather good as it can be grown in the cracks between slabs or crazy paving so that you tread on it to release its aroma as you walk. One tiny leaved mint that does well in our sandy soil is Corsican Mint.
Of course there are many plants that have aromatic foliage. I am starting to get an addiction to Thuja Plicata, but I can't make my mind up whether the smell is pear drops or pineapple. It does make trimming a hedge of it quite pleasurable. Most conifers have pleasant scents when brushed against or cut.
I think we concentrate too much on the visual aspects of a garden when planning the layout. All of our senses should be stimulated. As well as the fragrances there is the rustle of the leaves in the breeze, the feel of walking barefoot on the grass, (not to mention tree hugging, a challenge when you have a monkey puzzle), there are all the tastes from the orchard and vegetable patch.
I suppose that encouraging wildlife should also be included, the birds and butterflies are always nice to see. Not so sure about Peter Rabbit.
