About

Dahlia 'Gelia' (Misc) is a clump-forming, tuberous dahlia producing a long sequence of blooms from July to October. It makes a well-branched, rounded clump with green, occasionally darker foliage. Plant in full sun on neutral loam that remains moist but drains freely, in a south-facing, sheltered position. The cultivar carries an H4 (average) UK hardiness rating.

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 'Gelia' (Misc) is a tuberous, herbaceous perennial in the Asteraceae family grown as bedding and for cut flowers. As a clump-forming plant it produces multiple stems from its tubers and holds foliage that is usually green but can be darker on some plants. Flowering runs from July to October, providing a sustained supply of blooms later into the season than many summer bedding subjects. Place Dahlia 'Gelia' in a sunny, south-facing spot with protection from prevailing wind; a sheltered aspect helps stems remain upright and flower stems stay sound for cutting. It prefers a neutral loam kept moist but with good drainage — water regularly while actively growing but avoid waterlogging. The H4 hardiness rating translates to average winter tolerance for UK gardeners, so choose sites that do not expose tubers to prolonged wet and frost-prone conditions. Use this dahlia in mixed borders where it can form a mid-to-back planting block, in large containers on a sunny patio, or as a reliable source of stems for arrangements. Regular removal of spent flowers will encourage continued bloom through to October, making the plant particularly useful for extending the season of garden-supplied cut flowers.
