This small deciduous shrub will provide texture and color to your garden with its small blue-green leaves and bright yellow pin cushion-shaped flowers in July and August. The narrow bluish leaves and yellow clusters of flowers create a nice color contrast. This plant will attract numerous bees and butterflies. It’s a great choice for a pollinator garden or plant one near your vegetable garden to attract pollinators to that area of your yard.

Blues Festival Hypericum kalmianum 'SMHKBF' reaches 2 to 3 feet tall and wide in full sun conditions in USDA hardiness zones 4 to 7. The plant produces multiple stems and grows in a mounded shape that’s filled out close to the ground. This North American native plant is deer and drought resistant and salt tolerant.

Do not cut this plant back to the ground.
