Description

The classic Dahlia 'Mystery Day' has all the hallmarks of a good vintage, and has been bringing character, class and a touch of glamour to gardens for more than 30 years. In common with other decorative dahlias, Dahlia 'Mystery Day' has huge double, dinner-plate blooms up to 20cm across. But it stands out above the rest with its deep wine-red to purple petals, as rich and velvety as claret, each one tipped crisply in white. Backlit by the rays of summer sun, this creates a scintillating effect, adding more depth to those rich burgundy tones. A favourite in classic country gardens and stately homes, Dahlia 'Mystery Day' is a flower to treasure as one of the greats of the summer border.

Growing to just over a metre tall, Dahlia 'Mystery Day' holds its bold blooms up proudly, and has a longstanding reputation for keeping them upright. They jostle attractively with other plants and colours in the garden, working especially well with those rich autumnal shades as summer progresses and the light softens. Keeping on top of the deadheading means that you’ll be able to enjoy these beauties for a long season, from summer up to the first frosts. A standout plant for a big container, Dahlia 'Mystery Day' will thrive with a rich growing medium and regular moisture. You can also bring the drama of this dahlia into the home as a cut flower thanks to its excellent vase life.

Dahlias in 60 seconds

Dahlias like full sun and a free-draining soil, and should be lifted and stored in winter, or at least protected with peat or straw. Dahlia flowers can range from 5 to 25cm in diameter and those magnificent larger-flowering dahlias might appreciate a little extra support with canes!
