For many years, vegetables were not considered an ornamental addition to the garden, and veg plots were hidden out of sight or away from prized flowering beds and borders.

That is all changing, as many gardeners with limited space plant vegetables among border perennials, filling gaps with leafy lettuces, bronze fennel and wild strawberries rather than conventional bedding.

Vegetables can be easily combined in the flower garden, says Gardeners’ World regular Alys Fowler, presenter of a forthcoming new BBC2 series, The Edible Garden, and author of the accompanying book.

In her own 20ft by 50ft garden in Birmingham, Alys mixes veg with flowers throughout her borders, placing salvias next to tomatoes, broad beans and pink-flowering strawberries beside aquilegia, and makes bold statements with structural globe artichokes, rhubarb and courgettes.

Even if you only have a tiny space on your patio for a couple of pots, or just a window box, you can grow veg alongside flowers without it looking like a dog’s dinner, she insists.

And, it’s not just the veg that can be harvested. Pick off the flowers of violas and nasturtiums to make a colourful addition to salads, and they are also ideal for decorating chocolate cakes.

“Herb flowers, such as chives, sage or rosemary, can be added to oils and vinegars to offer a subtle flavour and enhance their appearance,” Alys says.

Ideally, to combine veg with flowers in a limited space like a container, make sure the container is at least 8in deep, otherwise what little soil you have in there is going to dry out quickly, she advises.

“Lettuces, rocket and radishes are good for window boxes as they don’t need much root run, while basil or thyme are suitable for really sunny spots. Traditional strawberries also like a lot of sun.”

However, you’re not just limited to lettuces in small containers, she notes.

Some tomatoes cascade happily from hanging baskets, such as ‘Tumbling Tom’, while small ornamental chillis, such as ‘Krakatoa’, are ideal in pots on patios and window ledges.

Even if you only have a tiny windowsill, alfalfa sprouts can be grown in a simple glass jar in just a few days, making a delicious and healthy addition to salads and sandwiches – and looking pretty at the same time.
