Ageratum's powder puff blooms are outstanding cut flowers and butterflies love them. Ageratum adds easy garden color in borders or containers from summer until frost.
CLOUD NINE WHITE Ageratum
Fluffy clouds of pure white flowers bloom extra-early on low, spreading 5″ tall plants. Leaves are smaller and growth is more uniform compared to other ageratums.
HAWAII 5.0 BLUE Ageratum
Six to eight″ tall plants with enormous flower heads in a beautiful shade of blue. An improved Hawaii Blue, with a higher germination rate and better garden performance.
DIAMOND BLUE Ageratum
Showing uncommon vigor, the branching, well-shaped plants reach up to 16″ high in the ground, yet are fantastic performers in containers. Diamond Blue is outstanding for massing in the landscape, mixing into borders, or for providing close-up, butterfly attracting color in patio pots.
BLUE HORIZON Ageratum
Blue Horizon blooms continuously from late spring to frost. Long-lasting, lavender-blue flowers on 18 to 30″ tall plants. One of the best ageratums for cut flowers.
How to Plant Ageratum Seeds
Plant floss flower: Sow seeds in cell packs or flats, press into soil but do not cover. Needs light to germinate. Kept at 75°F., germination is in 5-14 days. Can direct sow after all danger of frost in groups of 3-4 seeds spaced 6-12″ apart. Thin to the strongest plant.
Grow floss flower: Full sun in cooler climates, part shade elsewhere. Prefers rich, moist soil. Blooms are extraordinarily long-lived, dead heading is necessary, yet infrequent. Plants are low maintenance, resist rabbits and deer. Flowers attract bees and butterflies.
