Description

As you’d expect, Dahlia 'HS Romeo' is dashing and handsome, and it’s easy to fall for its charms! This single-flowered dahlia has a winning combination of dark, moody foliage and sumptuous velvety flowers in a cardinal red, with a delightful golden-yellow centre. If you’re looking for a long-flowering plant that adds a bit of drama to containers, this dahlia is the perfect fit, creating an attractive bushy presence, not much higher than 60cm. Dahlia 'HS Romeo' is also a hit with pollinating insects such as bees and butterflies, with its easily accessible open flowers, so it’s a great choice if you enjoy watching the wildlife in the garden or on the patio.

Great for adding interest in late summer and through the autumn months, Dahlia 'Happy Single Romeo' has a freely-branching habit, which means that it produces multiple blooms over a long period of time. Pinching out the growing tip will ensure a bushier shape and a regular regime of deadheading means that the flowering will just seem to go on and on. These dahlias love a sunny spot, but have also been known to do well in part-shade, making them versatile and useful. They thrive in containers with a good, rich compost and regular watering, and also make excellent plants towards the fronts of borders. The rich colours of Dahlia 'HS Romeo' blend fabulously with other shades of red, orange and yellow for an energising and mood-lifting display.

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!
