Dahlia ‘Double Pompone Mixed’
Standard pack: 25 seeds.
Produces beautifully uniform, ball‑shaped double blooms in bright, solid colours across a wide range of shades. The flowers are neat, eye‑catching and wonderfully reliable, held on strong stems that make them excellent for cutting. Plants reach around 90–120cm tall and will flower generously through summer.
Growing dahlias from seed gives you the best of both worlds — an affordable first‑year display and the chance to lift and store your own tubers for planting again the following season. Each plant forms its own tuber, making this a brilliant way to build a long‑lasting and varied dahlia collection.
