A jewel garden is planted with flowers in rich, vivid colours that resemble jewels all shimmering together in the summer heat. The best jewel gardens, such as Monty Don’s at Longmeadow, are a riot of vivid colours such as emerald green, rich sapphire blue, amethyst, gold and ruby red. While most jewel gardens involve drift planting in a large south-facing border, it’s possible to create a container jewel garden by planting in pots and positioning them close together.


When creating a jewel garden it pays to think a little about the location, aspect and exposure of your site. Choose a sunny, sheltered site where possible, with a moisture-retentive soil. It’s also important to make sure there’s always something in flower – from alliums in spring, to dahlias in autumn. Carefully plan what you will grow and where, and you'll have the perfect display for months on end.

Here are some plants that work well in a jewel garden.


Dahlia 'Bishop of Llandaff'

Dahlia 'Bishop of Llandaff' is a great choice for a jewel garden, owing to its striking, semi-double, bright red flowers, which appear from July to September. These contrast well with dark bronze stems and leaves.

Keep plants blooming by deadheading spent flowers and feeding with a high-potash fertiliser once a fortnight.
