Ageratum houstonianum, the Floss Flower. Cutting Ageratum should be started indoors 6 to 8 weeks before transplanting out after all danger of frost has passed. Sow seeds on top of soil mix, leaving the seeds uncovered but pressed firmly onto the soil surface, as light aids germination. Provide even moisture, strong light and luke warm water. Prepare a garden bed in full to partial sunlight with rich, well-draining soil. Harden off the seedlings by gradually acclimating them outside over 1 to 2 weeks. Carefully transplant them 8" to 12" apart. To encourage branching, pinch back the young plants at 8" tall. Keep them well-watered. Water at soil level only. For the best vase life, cut them once the fuzzy central flower cluster has opened and the side buds are showing pink color. Summer flowering.
