Urgent please

My son brought me some strawberry plants in containers - can I leave them outside or will I need to bring them in ?

 

Mine are still in the Ghouse Ming, We had Frost last night so im not chancing it, Ive planted them in my hanging basket (trailing strawbs) so when its time for them to go outside theyll be established..

 

OK ta, will bring them in because we're high up here and cold .x
