The powder puff blooms of Ageratum make outstanding cut flowers. And butterflies love them. Ageratums add easy color in borders, beds, or containers from summer until frost.
How to Plant and Grow Ageratum
Plant Ageratum Seeds: 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 in. apart. Thin to the strongest plant.
Grow Ageratum: 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.
