Plants that bloom in July in Zone 11 with blue flowers

Bachelor's Button

True cornflower blue that almost no other flower can match. Cottage garden classic that self-sows reliably.

Borage

Star-shaped electric blue flowers that bees go absolutely wild for. Self-sows freely.

Larkspur

Tall spires of spurred flowers in deep blue and purple. The annual cousin of delphinium, easier to grow from seed and just as dramatic.

Lisianthus

Rose-like ruffled blooms with the vase life of a chrysanthemum. The flower farmer's secret weapon for high-end arrangements.

Nigella

Sky-blue flowers wreathed in feathery green bracts give way to ornamental striped seed pods. Self-sows freely once you start.

Plumbago

Sky-blue phlox-like clusters bloom nonstop in warm climates. The blue flower that thrives where most blues melt in summer heat.

Statice

Stiff papery flower clusters that dry to keep their color for years. A cut-flower farmer staple for wreaths and dried bouquets.
