10 flowers for a jewel garden

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.
