Convolvulus tricolor
Safety & Hazards
None known
Cultivation Details
Requires a sheltered position in a well-drained low to medium fertility soil and a very sunny position[1]. 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[1]. An annual to short-lived perennial species, it is usually grown as an annual in Britain[1]. This plant is a very good attractant for hoverflies[1]. Hoverflies, and especially their larvae, are quite good predators on aphids.
Propagation
Seed - sow late winter/early spring in situ and again in May to ensure a succession of flowers[2]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Convolvulus+tricolor>
