Just ask Andrew Young, the president of the Port Macquarie Orchid and Bromeliad Society.

The Society is hosting its annual Winter Show this weekend (August 24-25) at Port Panthers.

Mr Young said there are over 200 plants on display as well as some commercial plants to sell.

He noted orchids are a popular plant across the world.

"Orchids are one of the largest families of flowering plants," he said.

"They grow in all conditions from equatorial tropics at sea level, right up to the snow line.

"They are native to every continent except Antarctica."

There are over 30 categories for orchid enthusiasts to enter at the show.

"We are looking for plants that have visual appeal, orchids that are round in profile and reasonably flat and looking at you," Mr Young said.

Mr Young first started growing orchids as a teenager.

"My science teacher gave me an orchid plant because he thought I might be interested, and I have grown them ever since," he said.

"I like them because they are forgiving in nature, much of my working life I have travelled a lot so I couldn't give them daily attention."
