Platycodon grandiflorus Blue (Balloon Flower) seeds
Winner of the Award of Garden Merit.
Packet of 50 seeds
Sowing Instructions: Can be sown at any time of year except early to mid-summer. Sow in pots or trays on the surface of a moist, well-drained seed compost (eg. John Innes). Do not cover the seed as light is beneficial to germination. Place in a propagator or seal in a polythene bag and maintain a temperature of 18-21C. Germination should take from 15-30 days and as the seedlings emerge, gradually increase ventilation by opening the bag or propagator vents.
Growing Instructions: Pot on when large enough to handle into 7-9cm pots and grow in cooler conditions. Overwinter if necessary in frost-free conditions, ie. greenhouse or insulated coldframe. In spring, gradually acclimatise to outdoor conditions, before planting out when all risk of frost has passed in a sunny position.
