About

Dahlia 'Wheels' is a tuberous, multi-stemmed, clump-forming herbaceous perennial that carries blooms from July to October. It has green foliage that may be occasionally dark-leaved and suits south-facing, sheltered positions. Plant types include bedding and perennial herbaceous displays, and it is commonly used for borders, containers and cut flowers. The plant performs best in loam with a neutral pH and soil that remains moist but well drained.

About the genus

Dahlias come from the high meadows of Mexico, and somewhere in that heritage is the explanation for how they behave here: tender to frost, hungry, generous beyond all reason. No other plant gives you quite so much for so little. One tuber, planted after the last frost, becomes a shrub's worth of flowers by August — and the more you cut, the more they come.The range is faintly ridiculous. Tight pompoms, spiky cactus types, singles the bees adore, dinner-plates the size of your face. Whatever your garden's mood, there is a dahlia that agrees with it, which is probably why every generation falls out of love with them and then, a decade later, falls straight back in.They're at their best when much of the garden is winding down — late summer into autumn, flowering hard until the first frost calls time. I think of them as the encore. And they always play it.

In the garden

Dahlia 'Wheels' is a tuberous, clump-forming herbaceous perennial that flowers from July to October and is grown as a bedding and border plant. The foliage is generally green, sometimes showing darker leaves, and the plant produces multiple stems from its tuberous rootstock, making it a reliable source of display over several months. Site selection matters: choose a south-facing, sheltered spot in loam with a neutral pH and soil that stays moist but drains freely. It prefers full sun, so avoid shade if you need abundant blooms. The UK rating H4 denotes average winter hardiness; place the plant where exposure is reduced to help protect the crowns during cold spells. Dahlia 'Wheels' fits several planting roles. Use it in mixed borders where summer and autumn colour is required, or plant in suitably large containers on a sunny, sheltered patio. It also provides stems for cut flowers, extending the indoor display well into autumn. Given its habit and flowering season, position it where the flower period from July through October will be visible and accessible for cutting or close viewing.
