 "pansa" grows in a similar manner to the classic garden forget-me-not, insofar as it is a short-lived perennial which self-seeds freely once established.It is, however, superior to its European relative as its foliage does not become bulky and scruffy in the way that "M. sylvatica" does at the end of a season.The subspecies is listed as Threatened - Nationally Critical on the 2017 New Zealand Threatened Classification for plants.
