Floss Flower - Garden Basics - Flower - Annual
(Ageratum houstonianum)
These
fluffy flowers are usually seen in blue, pink-mauve and white.
Tall forms grow to 20 inches while dwarf forms grow to only 6-8
inches. The dwarf forms make good edging plants. They can be used
as cut flowers if stems are scalded after picking and soaked in
cool water before arranging. They are not suitable for very cold
areas. Soil should be well-drained and enriched with manure or
compost well ahead of planting.
Sow seeds in early spring in pots or trays and lightly cover with soil. Transplant when 1-2 inches high. Space tall varieties 10-23 inches apart and dwarf types 4-6 inches apart. Keep the soil just moist but not soggy throughout the growing season. Mulching will help the soil retain moisture. Apply compost or other fertilizer monthly to maintain good growth. Aphids and whiteflies may become a problem, but these pests are easily hosed off and discouraged by an Soap-Shield.
