Botanical name:

Drosera auriculata

Common name(s):

Sundew

About:

D. Auriculata growth begins in late autumn and continues into early winter. Initially, a distinct rosette structure is formed that measures about 2-3 cm across, which develops numerous leaves over the course of approximately one to two months. Following this initial phase, a climbing stem emerges prominently from the centre of the rosette and grows rapidly upwards, with the stem producing shield-shaped cauline (well-developed stem) leaves at intervals of every 1-2 cm, ultimately reaching a height of about 15-30 cm.

Drosera species produce a droplet of sticky “dew” at the tip of each hair. Insects are attracted to the fluid but become stuck. Next, the hairs slowly bend inwards until the whole leaf has folded over the insect. Chemicals released from the hairs digest the insect’s body, and nutrients are taken into the plant.

Natural habitat:

Coastal to montane, on recently exposed and naturally open ground, clay pans, in low scrub, on lava. Often abundant following fire.

Growing environment:

Wetland, Wind & Clay tolerant.

Endemic distribution:

New Zealand’s North and South Islands to about south Canterbury, northern Otago and south Westland. Present in Australia also.

Fruiting:

October - April
