Despite its beauty, Flossflower has the potential to become invasive outside of its native range, and it has been naturalized in several parts of the world. It thrives in cool, moist soils and enjoys full sun. The plant typically reaches a height of 30–60 cm and blooms from May to November in the northern hemisphere.
Flowerheads: Blue, purple, pink, or white in dense clusters.
Plant Type: Herbaceous, annual plant.
Height: Up to 60 cm.
Blooming Period: May to November.
Hardiness: Prefers cool soils and full sun exposure.
Toxicity: Contains pyrrolizidine alkaloids which can be toxic to grazing animals.
Chemistry: Produces a compound that interferes with insect growth, making it resistant to pests.
Soil Requirements:
Flossflower thrives in well-drained, cool soils with a slightly acidic to neutral pH.
Sowing Instructions:
Best Time to Sow: Start sowing in spring after the last frost or indoors 6–8 weeks before the last frost.
Germination Temperature: 72 to 75°F (22 to 24°C).
Germination Time: 10–14 days.
Sowing Depth: Press seeds lightly into the soil and cover slightly, as the seeds do not need light to germinate.
Watering: Keep the media moist and near saturation until the seeds germinate.
Transplanting & Care:
After germination, grow the seedlings in cooler conditions with less moisture.
Once large enough to handle, transplant to trays or directly into their permanent positions in the garden once all danger of frost has passed.
Gradually acclimatize the seedlings to outdoor conditions before planting out permanently.
Feeding:
Do not fertilize until the plants are mature and flowering, as young plants do not require feeding.
Watering:
Water the plants regularly to keep the soil moist, but avoid waterlogging, which could lead to root rot.
Once established, reduce moisture levels to encourage stronger growth.
Pruning:
Deadheading spent flowers will promote continued blooming and keep the plant looking tidy.
Protection:
Be cautious of over-fertilizing, as this can result in weak growth.
Ornamental Use:
Flossflower is widely grown for its fluffy, colorful flowers in gardens, balcony boxes, and as cut flowers for floral arrangements.
Available in several varieties, with blooms ranging from blue to purple, pink, and white.
Invasive Species:
Although it is a beautiful ornamental plant, Ageratum houstonianum can become invasive in areas outside its native range, including the United States, Australia, Europe, Africa, and Asia.
Toxicity:
Contains pyrrolizidine alkaloids, which can be toxic to grazing animals, causing liver lesions if ingested in large quantities.
Pest Resistance:
Ageratum produces a unique chemical compound that interferes with insect growth, making it resistant to many pests. It can be beneficial for garden beds where insect pests are a concern.
Flower Color: Blue, purple, pink, white.
Plant Height: Up to 60 cm.
Exposure: Prefers full sun.
Toxicity: Contains pyrrolizidine alkaloids, toxic to animals.
Hardiness: Prefers cool soils.
Sowing Depth: Lightly press seeds into the soil.
Germination Time: 10–14 days at 72–75°F (22–24°C).
