About

Dahlia 'Bishop of Dover' (Bishop of Dover Dahlia) is a tuberous perennial cultivar within the Dahlia genus, which comprises bushy, tuberous herbaceous perennials native to Mexico and Central America. As a member of the Asteraceae family, it thrives in full sun with a south-facing aspect and can tolerate conditions from sheltered to exposed. It prefers well-drained, fertile soil that is neutral to slightly acidic and moist but well-drained. Suitable for borders, containers, and cut flowers, it requires planting tubers after the last frost, staking if tall, and deadheading to promote blooms.

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.
