Fluffy plant

This is a wild guess - I have an idea that it is called 'Asparagus Fern'.

Another guess, I don't think it's a Fern, the fronds don't look right. Do some googling on Sage plants.

Can you get a close up of the leaves and flowers, preferably with a piece of white paper held behind them?

It's an Aspasagus fern. Not a true fern but a flowering plant and it will have tiny flowers and later on there may be small red berries. Definately Asparagus fern. : )

Definitely Asparagus. It is an edible asparagus seedling, do you have asparagus growing near you? These seedlings will pop up anywhere.

Be careful - Asparagus is, of course, edible. BUT Asparagus Fern is not edible! Don't think the fern grows outdoors in UK, but I might be mistaken - what with global warming!

Asparagus fern is hardy and can grow outdoors in West Wales. Don't know about the rest of the UK further north.

I have grown this Asparagus in Essex, it does very well, and the fern looks lovely in with my cut flowers :) Jackie x
