Dahlia 'Amorangi Joy' is a cultivar of Dahlia, a genus of perennial plants with tuberous roots and finely dissected leaves, known for their prominent flowerheads. This bushy, clump-forming herbaceous perennial thrives in full sun on south-facing, sheltered sites with moist but well-drained loam soil of neutral pH. Suitable for borders, containers, and cut flowers, it is hardy in the UK (H4) and typically flowers in spring. Cultivation involves well-drained soil and sun exposure, with propagation by division, cuttings, or seed.
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.
