Entretien

Plant these in a sunny spot with plenty of space to accommodate their height. Keep an eye out for aphids on the flower heads, and make sure the soil does not dry out completely during the first year. Since they are biennials, they will die back after setting seed, so let them drop seeds if you want them to return.

Ce qu'on demande souvent

Is it a perennial?

It is a biennial, growing as a rosette the first year and flowering the second.

How do I stop it from spreading?

Cut the flower heads off before they go to seed.

D'où vient le nom

The genus name Dipsacus comes from the Greek word for thirst, referring to the water collecting leaves, while fullonum refers to the fullers who used the heads for cloth.

Bon à savoir

• Teasels are monocarpic, meaning they die after flowering once.
• The cup shaped leaves collect rainwater, which can drown small insects.
• A single plant can produce thousands of seeds that remain viable for years.
