Notes
'Florist Blue Boy' centaurea (Centaurea cyanus 'Florist Blue Boy') is an annual for borders, cut flowers, and cottage gardens. It grows well in cool weather and can ride out a light frost. This plant likes full or part sun and average to moist, sandy, loamy, or clay soil. Its deep blue blooms are classic cornflowers that open in spring and summer, and butterflies, bees, and birds visit them. Deer rarely make it their first choice. It also tolerates drought.
Pairs well with Double Zahara Cherry zinnia, Red fescue, and Old Rose Dandy peony.
