Silky Purple Flag image pc300393 102KB

A most delicate and stunning flower that only lasts a day.

A member of the Iris family - family Iridaceae - whose 1,500 species world-wide include freesias, gladiolis, crocuses, and of course irises.

There are about 80 genera (sub-families) of which the Patersonia genus is one. There are about 19 species in this genus - most of which only occur in the south-west of Western Australia.

The New South Wales Flora Online web-site details four of these. Two of which are included below.

The Silky Purple Flag (Patersonia sericea) is the most common species on the East Coast.
