Oxalis debilis

Lilac oxalis

Other common names:

Pink shamrock, pink wool sorrel, purple oxalis.

 

Description:

Lilac oxalis can grow 10 cm to 15 cm tall. The weed has dark green heart shaped leaflets which can be 2 cm to 4.5 cm long. The funnel shaped pink or mauve flowers which are very distinct are borne in clusters of 2 to 6 flowers. The weed grows from underground bulbs and does not produce any fruit. Pink shamrock (Oxalis debilis var. corymbosa ) is regarded as a minor environmental weed in Queensland, and as a "sleeper weed" in other parts of Australia (Weeds of Australia, 2016).
