Blue Mink Ageratum Seeds (Blue Flossflower) 5000. Giant trusses of fluffy, true-blue flowers. Plants are upright, early flowering and vigorous yet compact in habit growing only 20-25 cm (8-10″) tall with a spread equal to that. Great for borders or for using as a cut flower. Since it dislikes being transplanted, we recommend that to get a head start on the season, seeds should be sown in peat pots indoors in late winter. Transplant the seedlings, peat pot and all after danger of frost has past.
