Dahlia Seeds
Dahlia seeds are a must-have for gardeners looking to create showy, colourful displays that last throughout the summer. These bushy half-hardy perennials, native to Central and North America, are loved the world over for their unique textures and broad palette of hues – ideal for adding interest to any garden.
At D.T. Brown, we offer favourites like Pompon Mixed, a charming blend of tightly layered blooms in bright and cheerful tones, and Bishops Children with its rich sunset-hued single flowers and bronze foliage. For something that truly makes a statement, Collarette Dandy produces striking blooms with an inner collar of petals, some in contrasting colours. Explore our seed dahlia collection and bring your summer beds and borders to life.

Growing Dahlia from Seed
Dahlias provide a real spectacle in the summer garden, their unbeatable displays beginning from mid-summer and continuing right the way through to the first frosts. These beloved blooms are a particular favourite of British gardeners, not least because of the fantastic range of flower shapes and colours they offer but because they can be treated like a hardy annual flower growing through all types of climates. Their tall stems make them an excellent addition to the cut flower garden.
Sow your dahlia seeds indoors and keep them warm and humid – use a heated seed bed or windowsill propagator for best results. Deadheading will help encourage more blooms during the flowering season. Though dahlias are perennial plants, they are not hardy, so we recommend lifting the tubers and storing them indoors to overwinter if you want them to flower again next year.
If you’re looking for a faster, more reliable way to grow dahlias, be sure to explore our excellent range of dahlia tubers.
