About

Dahlia 'Magenta Magenta' is a cultivar of the Dahlia genus, known for its tuberous roots and finely dissected leaves. This herbaceous perennial grows with a columnar upright habit, reaching heights of 1 to 1.5 metres and a spread of 0.1 to 0.5 metres over 1 to 2 years. It thrives in full sun and prefers moist but well-drained soil of various types and pH levels. Deciduous in nature, it flowers from spring through autumn and is suitable for city, courtyard, cottage, and informal gardens.

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.
