Solved ID please

Hi all! My sister's been growing offshoots from my uncle's old plant - firstly, what are they(!) and secondly are they likely to be hardy enough to go outside?

Thanks!

 

They look like Pelargoniums.
They can't go outside until the risk of frost has gone.

 

Thanks punkdoc!

 

You could start acclimatising them now by putting them outdoors during the day and bringing them back in at night until frost is no longer a threat. I've had some outdoors for a couple of weeks now but it's quite mild here. It depends on your location and weather.

 

And thanks Plantminded!
