Notes
'Tall Blue Boy' centaurea (Centaurea cyanus 'Tall Blue Boy') is an annual for borders, cut flowers, and cottage gardens. Cool weather suits it, and it can take a light frost. This plant likes full or part sun and average to moist, sandy, loamy, or clay soil. Its deep blue flowers open in spring and summer on erect stems, and bees, butterflies, and birds visit the blooms. Deer rarely make it their first choice. It is also drought tolerant.
Pairs well with Easy Wave Red petunia, Double Zahara Cherry zinnia, and Red fescue.
