How to grow Ageratum

Annual, bedding plant, readily available in flower in later spring; this flowering continuing until mid summer. If the stems are cut back then, the plants will flower for a second time in early autumn.

Situation:

Chiefly used in beds and annual borders. May also be used under other plants, for instance roses.

Soil:

Will grow in any reasonably nutritious soil. Propagation:

In February, seeds of the so-called Fi hybrids are sown in a heated greenhouse or frame at a temperature of 18-20°C. Seedlings are pricked out, kept even warmer, and are finally hardened off. In later winter, cuttings may be taken from overwintered plants.

Ageratum houstonianum: Height 10-20 cm.
