Zinnia elegans. Each flower opens as a conventional looking Zinnia, but then ruffles from the centre with so many petals that it resembles the pincushion flower, Scabiosa. Hence its inclusion in the 'Scabiosaflora' series. The truly handsome blooms top tall, upright stems that are superb as cut flowers. The plants grow to 75cm (30") tall, and produce from early summer right into September. These flowers drew consistent interest in our summer seed trials, and made it into a great many bouquets. Direct sow Lemon Cupcake Zinnia seeds, and begin cutting flowers in as few as nine weeks.

Just cover Zinnia seeds, and aim for a final spacing of 25-30cm (10-12″) between plants.
