September 1 is known as Wattle Day, but thanks to a warmer Queensland winter many of the bright yellow blooms have already been and gone.
"I saw some wattles blooming in autumn," said Alison Langdon, president of the Toowoomba-based Society for Growing Australian Plants.
"At the moment everything is at least two weeks early."
It is not only the wattles that have made an early entrance. Warm winter days have meant many plants set flower buds early.
"There are heaps of Australian flowers blooming at the moment," Ms Langdon said.
"Most people know grevilleas, but there's also a lot of native fuchsias too," she said.
"A lot usually come out in summer, but many are out now."
Two-time grand champion Toowoomba gardener Bob Ford said the long, cool nights with some recent frosts had not been helpful to city gardeners.
But he expects blooms to be bountiful for the city's annual Carnival of Flowers in a fortnight.
"The cold nights have cut the blooming back a bit," he said.
"The flowering peach and cherry trees are going to be a little bit late this year, but there will be plenty of colour for the carnival."
"But we are getting sick of watering," he said.
Darling Downs grain grower Wayne Newton said winter crops fared well during the warmer winter, but over the past several weeks severe frosts had started to cause damage.
"Cereal crops are about to start pushing into head in some areas and so the water demand is really increasing," he said.
"Our wishlist is for some rain, and then some more rain, and then some continuing mild weather.
Professor Roger Stone, director of the International Centre for Applied Climate Sciences at the University of Southern Queensland, said weather models pointed to a "slightly wetter and slightly warmer" spring.
"It comes up slightly above average at this stage, particularly for the Darling Downs," he said.
"It's unusual for this time of year to see a major change in our seasonal climate patterns. But that actually looks like what may happen."
According to Bureau of Meteorology data, Toowoomba received 2mm of rainfall during August 2017. The average mean rainfall is 39.5mm.
