Not necessarily. Large or dinner-plate-sized dahlias are generally selected and maintained through specific cultivars propagated by tubers or cuttings. Seed-grown dahlias can produce different flower sizes, colors, and petal arrangements because of genetic variation. Check the seed variety description if large blooms are an important requirement.
Dahlias are genetically variable plants, and seedlings inherit different combinations of characteristics from their parents. As a result, plants grown from seeds may differ in flower color, size, petal arrangement, and overall appearance. Tubers or cuttings are generally used when the exact characteristics of a particular dahlia variety need to be maintained.
Provide at least 6 hours of sunlight daily, maintain consistent soil moisture, and grow dahlias in fertile, well-drained soil. Remove faded flowers regularly to encourage additional flowering. Pinching the growing tip when plants are established can also encourage branching and more flowering stems.
