Ageratum houstonianum (hybrid)
Long-lasting blooms like tiny explosions are out of this world in gardens or containers, and especially planted in mass. This tall ageratum branches without being pinched back and flowers prolifically. Accents well with bright white flowers in the garden bed or in bouquets. Plants grow up to 24″-30″ tall, 8″-12″ wide, and produce flowers that bloom from summer to frost. Prefer full to partial sun exposure.
