While trading has ground to a halt during both the Sydney and regional NSW lockdowns, there is one business defying expectations.

Blooms of Bowral opened little over two years ago and has had both bushfires destroying stock and a once-in-a-century pandemic to deal with so far.

But for owner Michelle Clayton, a rough start to life has seen her florist grow beyond her wildest dreams.

"When I bought this shop two and a bit years ago I thought I was just buying a little flower shop but it has just gone crazy," she told the Southern Highland News.

"The flower business has taken off so much we are actually moving into a larger premises.

"When Covid first hit we were taking on staff and we've carried all those staff through and we're still putting on staff. My staff base is just growing and growing which is fabulous."

The Bowral operation will be staying in High Street as it continues to capitalise on a surging demand for flowers.

Michelle said with her business already heavily reliant on online ordering and delivery, operations have remained relatively normal.

"It's actually made us quite busy," she explained.

"What happens is when people can't visit, one of the first things they can think of to deliver is flowers because florists always do deliveries whether it's a lockdown or not.

"Nearly every card has had a message about catching up when lockdown is over on it.

"We're already set-up for delivery and have a really successful website that Sydney people can jump on and with locals not able to visit it's made us quite busy."

With growers bouncing back after the Black Summer bushfires, Michelle said Blooms is relying on local suppliers to fill orders.

She urged customers to ask for seasonal varieties to ensure they are supporting Highlands businesses.

"The problem we had last year was that we'd had the bushfires so natives were very hard to get hold of and when the lockdown was announced flowers were in demand," she said.

"We're lucky that we utilise a lot of local growers. We use every single local grower between Tallong and Thirlmere and use the Sydney market to supplement what they don't grow.

"The local growers started growing more and saw that people were interested in purchasing flowers so their production rose."
