Ageratum, Dondo Blue (Organic)
Ageratum houstonianum. 45 days.
Tiny fuzzy purple flowers form in nice sized clusters on long stems making a great filler for bouquets. Long season makes it great for the garden, too! Many modern ageratums have been bred to be dwarf bedding plants, but Dondo Blue maintains the taller stature loved for cut flower production. Stems of Dondo Blue found their way into almost every weekly bouquet we made from midsummer through frost, adding nice texture and complementary color. Deer resistant. May self-sow. Aka, Floss Flower, Bluemink.
Surface sow in pots indoors 6 weeks before last frost. Germinates in 7-10 days at 70˚F soil temperature. After danger of frost has passed, transplant to 10” centers. Prefers full sun to part shade, fertile soil, and good drainage. Pinch back the growth tips of young plants to encourage more stems to form, and deadhead any unharvested flowers to prolong bloom.
Seed Saving
To save seed, sow plants early in spring & harvest when seeds easily rub out of seed heads. Cut seed stalks when seeds are dry, thresh by hand, dancing, or hitting seed stalk against sides of bucket. Screen to clean.
