Prepare to be awestruck by the sheer scale of 'Incrediball®'. This show-stopping shrub produces colossal, volleyball-sized flower heads that can reach up to 12 inches in diameter. Each massive dome is packed with thousands of tiny, star-shaped florets that emerge a refreshing lime green, mature to a crisp, snowy white, and then age to a sophisticated pale green. Held high on thick, woody stems that refuse to flop even under the weight of a summer rain, these "snowballs" create a dramatic, high-end look in any landscape.
