"Orchids are blooming early in the shade house at Cranbourne Royal Botanic
Gardens this winter.
“We usually don’t see these warmer temperatures until early spring,” orchid
conservationist Alex McLachlan said.
“This has brought about early flowering and early germination for a lot of our
orchid seeds and flowers,” like the Caladenia valida orchid species, which is
flowering two months early in the Victorian gardens.
Shade houses are often warmer than the wild, said Dr Noushka Reiter, a senior
research scientist also from the Cranbourne Royal Botanic Gardens.
“So if you have a little bit of extra warmth outside, that is retained within
the shade house and then it pushes those plants on a little bit further.”
A warmer winter is changing the way plants “normally act”, McLachlan said.
Temperatures have been fluctuating in “fits”, with warm waves followed by cold
spells, “which can cause things to happen before they should”, said Dr Kara
Youngentob, an ecology research fellow at Australian National University.
“You see examples all over the place,” she said. “Just walk out your front
door. There’s no doubt about it. The climate is warming and as a result, nature
is responding,” Youngentob said."
