Ageratum seeds — fluffy blue cushions all summer
Ageratum, the floss flower, forms low mounds smothered in soft, powder-puff clusters of blue, mauve, pink or white from early summer until the frosts. These tidy, long-flowering annuals sit comfortably within our annual flower seed range. New to flowers? Our flower growing guide gets you started.
Few flowers hold true blue as well as ageratum — the calendar shows when to sow.
An edging and container classic
Compact and neat, ageratum is made for the front of a border or a pot, earning its place among our container-friendly flowers, while the nectar-rich clusters draw in bees and butterflies as one of our bee-friendly flowers.
Growing ageratum from seed
Sow under cover in early spring, barely covering the fine seed, and keep it warm and bright. Plant out after the last frost into full sun or light shade, water in dry spells, and pinch off faded heads to keep the cushions covered in colour right through summer.

¿Es el ageratum anual o perenne?En nuestro clima, el ageratum se cultiva como anual semirresistente, sembrándolo cada primavera y floreciendo hasta las primeras heladas.
¿Cuánto crece el ageratum?La mayoría de los tipos de jardín se mantienen compactos, alrededor de 15–30 cm, lo que los hace ideales para borduras, la parte delantera de los arriates y macetas.
¿Cuándo debo sembrar semillas de ageratum?Siembra bajo cubierta a principios de primavera, cubriendo apenas la fina semilla, y trasplanta después de la última helada. Consulta nuestro
calendario de siembra de flores para los tiempos.
¿Atrae el ageratum a los polinizadores?Sí — los racimos ricos en néctar son un imán para abejas y mariposas durante el verano.
