Flowering
From Early Summer TO Early Autumn
Acmella oleracea flowers through Summer, from early Summer through to early Autumn
Planting
From Late Spring TO Early Summer
Plant in a sunny or partially sunny site in any type of soil as long as it is free-draining. If plants were started off in the greenhouse, plant them out in the evening, and water deeply.
Propagate by stem cuttings
From Late Spring TO Early Summer
This plant can be propagated by stem cuttings. Choose a stem that is already rooting. Cut the stem near the crown, keeping attached rootlets intact. Plant this in a pot, or direct into the garden after all risk of frost has passed, into a sunny, or partially sunny site, into free-draining soil. Water well, and keep well-watered while the new plant establishes.
Propagating by seed
From Mid Spring TO Mid Spring
Sow seed in a greenhouse, if you are in a temperate climate. In a tropical climate the seed can be sown direct in the soil. Avoid damp or cool conditions, or the seeds may rot. In the right conditions, seeds should germinate in about 12 days.
