Named for the chivalrous knight from the legend of King Arthur, Galahad produces tall spires of pure-white satiny flowers, rising from rich green mounds of foliage. The quest for the perfect delphinium is over - profuse, immaculate semi-double flowers make Galahad the 'grail' of your border planting.
Sow into trays of Yates® Black Magic® Seed Raising Mix. Firm down, water gently and keep moist through germination period. Transplant when large enough to handle.
Choose a sunny well-drained, sheltered position. Add Yates® Thrive® Natural Blood & Bone before planting. Fertilise regularly with Yates® Thrive® All Purpose Soluble Fertiliser, and switch to Yates® Thrive® Flower & Fruit Soluble Fertiliser when first buds appear. Keep well watered. Protect from snails and slugs.
If plants are likely to require staking for support, ensure stakes are placed in position at planting time.
Store in a cool dry place away from direct Sunlight. Keep out of reach of children and pets.
