Rain unearths rare SA plants

Widespread rain across South Australia has helped unearth a new species of native mint and set the state's rarest flowers blooming.
Staff from the Adelaide Botanic Gardens have rediscovered seeds from some of South Australia's rarest native plants, Minister for Environment and Conservation Paul Caica says.
"Widespread rains and flooding have seen a range of desert flowers and plants blossom and thrive in what have been dry and barren inland landscapes, such as the Cooper Basin," he said in a statement on Tuesday.

Seed hunters have found some rare outback plants such as the endangered Arckaringa daisy, which is known from a single population in the Arckaringa Hills in the state's north.
They also found the orange-flowered twin leaf, swainson-pea, peplidium, breakaway daisy and goodenia and a new species of native mint growing in SA's southeast.
The seeds they collect are stored at the SA Seed Conservation Centre to safeguard against extinction and future threats.
Since it opened in 2002, more than 175 million seeds from more than 1400 SA native plant species have been collected and stored by the centre, including 50 per cent of SA's threatened plant species.Staff from the Adelaide Botanic Gardens
