About

Dahlia 'Northlake Heritage' is a tuberous, clump-forming herbaceous perennial in the Asteraceae grown for summer–autumn blooms and use as a border, container and cut flower plant. It flowers July to October. It prefers full sun on a south-facing, sheltered site in loam with a neutral pH and soil that is moist but well-drained. Foliage is normally green and can occasionally be darker-leaved.

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 'Northlake Heritage' is a tuberous, clump-forming herbaceous perennial within the Asteraceae family, cultivated for its long season of blooms and suitability for cutting. Flowers appear July to October, providing sustained colour through late summer and into autumn. The plant produces multiple stems from its tubers and is used in traditional mixed borders, large containers and for floristry. Position the dahlia in full sun on a south-facing, sheltered aspect to reduce wind damage to stems. Plant into loam-based soil or a loam-rich container compost with a neutral pH; maintain a balance of moisture without waterlogging, as the plant favours moist but well-drained conditions. In the UK it carries an H4 rating (average hardiness), making it appropriate for many gardens when positioned in a protected spot. Use it to build summer–autumn structure at the front or middle of a border, or in sizeable containers where the loam mix can be managed for steady moisture. It is also suitable for cutting work: the stems carry blooms that are practical for domestic arrangements from July through to October, and regular picking supports the plant's role as a dedicated cut-flower dahlia.
