The picture you posted are of Homebase bedding plants. (I know as I work in the garden centre there :P )
Those particular varieties are very hardy, Ive had them in the garden centre for approx 2 weeks and I just cover them before I leave the store with frost fleecing.
Havent lost 1 pack yet!
Although I would still be cautious planting them yet as the ground is still so cold.
Wait til the weekend at least when its due to warm up a bit then if any frosts are due after that just cover them up
