Not just another yellow double Daffodil, Thunderball brings spellbinding color and a petal–packed punch to the garden. When its layers of sunshine–yellow petals open, this daffodil reveals a light green heart at the center of each flower. Bold, heavily layered petals open to over four inches across, on tall, sturdy stems. This mid–to–late spring flowering daffodil will ease your landscape into the warmer months with the juxtaposition of a springy daffodil form and near–neon coloring. Perfect for planting in a row, container or window planter. Narcissus 'Thunderball'
