Not for Patrick Jones and Meg Ulman though, who often find their food in the most unsuspecting of places. 

The pair and their two children Woody and Zephyr, are most recently known for spending a year bike-camping along the east coast of Australia eating only what they found, hunted or were given. 

For their 9000 kilometre trip, they foraged for tucker in the bush and even on roadsides surviving on a $35-a-day budget. 

Now they are bringing those skills to fellow Daylesford residents in a weekly course, which is designed to shine a new light on the humble weed. 

"We are at our peak affluence as a society where the non-monitory economy is devalued," he said.

"This is about giving knowledge in the face of all of that."

During the two hour walk people will learn to identify 25 to 30 species of edible weeds all living on their doorstep. 

Even when visiting his Daylesford home, Mr Jones offers huge salsify roots from his nature-strip. 

They're perfect for roasting - similar to a parsnip. 

In reality, it's only been in the last two generations when people have stopped turning towards these edible plants. 

It is a key part of Indigenous culture, but with consumerism taking over people are turning towards big chains to provide their food. 

In Mr Jones' opinion, the world is worse off as a result. 

"Farmers would so often supplement their diet with these foods because they are natural preventative medicines," he said. 

"Our modern food system is so lacking in nutrients, we try to replace all that goodness with medicine. 

"But if we take control of our food and find these wild roots, it's better for our health, the environment and it's also affordable."

Mr Jones has been foraging since he was a young boy, but has learnt a lot about different cultures since his Australian bike trip. 

Of course, there are dangers in not knowing when you pick weeds from the ground for food.

But Mr Jones said knowledge was a powerful thing. 

"It's not like we do this solely for climate change or to change the system," he said.

"We do it because it's how we live and now we want others to empower themselves. 

"These is an immediacy in this, there is power and there is adaptability." 

The course will be held every Saturday from 10am. Bookings via 0418 523 308 or email permapoesis@gmail.com
