Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – an interim threat classification status has not been assessed by the NZTCS panel.

Brief description
Forming small rosettes on bare soil or in garden pots; strigose-hairy leaves. At first sight, it resembles a hairy form of C. corymbosa.
Distribution
Scattered records, mostly in disturbed sites. Its small size means it is probably under-recorded to date.
Habitat
Disturbed sites—garden pots, earth paths.
Similar taxa
Cardamine corymbosa, but the leaves of C. heleniae are conspicuously hairy.
Flower colours
White
Life cycle
Prolific seeder and establishes freely; it has considerable weed potential.
Propagation technique
Seed
Etymology
cardamine: From the Greek name kárdamon, referring to an Indian spice
