Cultivation
This section contains historical Plants For A Future notes marked noncommercial.
Requires a sheltered position in a well-drained low to medium fertility soil and a very sunny position[2]. This plant is generally hardy to zone 8 (tolerating temperatures down to about -5°) but some forms are much hardier and can tolerate temperatures down to about -20°c[2]. An annual to short-lived perennial species, it is usually grown as an annual in Britain[2]. This plant is a very good attractant for hoverflies[2]. Hoverflies, and especially their larvae, are quite good predators on aphids.
