Dahlia Dandy

Dahlia Dandy (Dahlia pinnata) is a charming, compact dahlia variety grown from seed, prized for its vibrant single blooms and attractive dark foliage. The pinwheel like flowers, which come in shades of red, pink, orange, yellow and white, with a unique set of central petals, often with contrasting colours that attract bees and butterflies. The plants are bushy and free-flowering, making them ideal for containers, garden beds and cut flower gardens.

Unlike tuber-grown dahlias, the ‘Dandy’ series is easily grown from seed and offers a more compact size. This makes them perfect for smaller spaces, edging borders, or brightening up patio pots. As cut flowers, their vivid colours provide excellent material for casual summer bouquets.

Home gardeners can sow Dahlia Dandy seeds indoors in late August to October, using seed trays filled with a free-draining mix. Sow seeds 5 mm deep and keep them at 20–25?°C. Germination takes 7–14 days. Once seedlings have developed a few true leaves and the risk of frost has passed, they can be transplanted outdoors, spaced 25–30 cm apart. Flowering begins around 90–100 days from sowing.

Dandy dahlias prefer full sun and rich, well-drained soil. Regular watering is important, especially during dry spells, but avoid waterlogging. Removing spent blooms (deadheading) will encourage continuous flowering through summer and into early autumn. Easy to grow and full of colour.
