Why flowers blooming all year round may be cause for concern

Why flowers blooming all year round may be cause for concern

Native flower farmer Annabelle Greenup has had an annual winter break, when her crops were dormant and not in bloom, for more than 24 years.

But this year, her western NSW business experienced a first: consistent flowering all year round.

“There’s been super early flowering of lots of things, things that you’d expect to be flowering in about a month’s time,” Mrs Greenup said.

Industry experts have said the trend is not uncommon, but it has not been seen this extreme. 

Mrs Greenup and her husband Anthony O’Halloran said while the early blooms were great for business, they were very unusual.

“Though it was a dampish, coolish winter, it really wasn’t cold,” Mrs Greenup said.

“We’ve been able to pick things the whole time.”

Mrs Greenup said there would usually be up to 100 frosts a season at her Binnaway property, but this year there had only been about 30.

“Our banksias typically come into flower November right through to May and then we usually can’t keep picking because they get damaged,” she said.

“But this year, we have been able to just keep picking some.”

Change in climate 

Excessive winds experienced in western NSW have also caused flowers to dry out rapidly.

“Some of the inland hakeas and the hybrids we’ve bred, they’ve really aged very quickly,” Anthony O’Halloran said.

“So the dry warm conditions have really wilted a lot of them.”

The conditions have caused some unease for the Bilby Blooms owners, who hoped they would not mean a repeat of 2019, which the NSW government declared asdrier and hotter [conditions] than any other NSW drought in the last 120 years”.

“It’s been just so warm, and 2019 was very warm with little rain,” Mr O’Halloran said.

“As long as we get regular rain, it will be good, but if it dries off, it will be interesting.”

Concern for the environment

Chief scientist for wholesale flower and plant supply company Lynch Group, Scott Salter, said while he had seen some variations in flowering time because of climate changes, he couldn’t recall seeing anything as extreme.

“In cut flowers, some plants are especially susceptible to temperature and we do see some effects on wild harvested flowers that show quite some difference in flowering compared to the scheduled time of flowering,” Mr Salter said.

“As the climate continues to warm, we will see examples of these types of effects more and more.”

Mr Salter said the effects of warmer weather were not ideal for the industry as there was the potential to miss market opportunities.

He also said it was a major concern for the environment.

“Plants often rely on pollinators that they have co-evolved in order to spread genetic material and enhance natural genetic diversity,” Mr Salter said.

“If the flowers are available earlier [or later] than the pollinators are ready or optimised for them, this can have consequences.”
