No summer garden should be without dahlias. Perfect for the border or the cutting patch, they flower for ages in a host of bright colours, from white through to almost black. Grow them from tubers in spring for the best choice of varieties, or buy ready-grown plants at the garden centre in summer.


The colour you choose will depend on your chosen colour scheme - red and crimson dahlias offer a pop of colour and looks great in 'hot' borders or pots.

Here are eight red and crimson dahlias to grow.

Stake dahlias to prevent flopping

Dahlias have a tendency to flop when in flower, so stake them discreetly before they begin to bloom.
