Sundew flowering

Scented Sundew

There are changes that signal the coming of spring – the flowering of wattle and clematis, for example. And, the flowering of the Scented Sundew.

The Drosera Aberrans – Scented sundew – is only a low growing plant, with gorgeously coloured leaves in reds and greens. The plants are dormant during the summer and have emerged from their tubers during autumn and winter, carpeting the ground in moist, clay spots. Here, they are generally found with mosses and lichens.

The flower has a sweet scent, although we couldn’t detect it – maybe because of the remains of a cold.

It seems that those plants growing in more shaded areas tend to be green, as illustrated below, although green also occurs in more sunny spots and reds also occur in more shady spots.

Their source of nutrition – useful in the low fertility soil characteristic of the native bush here – is from the insects caught in the sticky liquid produced at the ends of the plant’s lamina. This dewy shine is where the name ‘sundew’ comes from.

The Scented sundew produces new plants mainly asexually. Stolons shoot near the soil surface and then burrow down into it, producing new plants.

The Tall sundew can also be found in the Reserve and will flower – a pale pink colour – a bit later.
