Ageratum

~7,000 seeds/g.

Annual. Its name means ‘not growing old’ as the flowers retain color for a long time. Also known as Flossflower. Covered with blossoms, great for summer borders.

Culture: Start indoors at 80° for 6–8 weeks before last frost; grow on at 60–65°. Set 9–12" apart. Likes full sun. Water in hot weather. Extreme temperatures inhibit flowering. Will not tolerate frost. Cut for vase when flowers are first opening.
