I've just received some primula viallii plants in the post and was
wondering whether they could go out into the border straight away. I
had a look in Hessayon but he's very vague on which primulas like wet.
My border is boggy and cold in the winter (though p.denticulata do
very well in it). They are in pots and very little showing except
tiny shoots in a few of them. If I shouldn't put them out will they
be ok outside unprotected or should I put them in the greenhouse
(slightly heated but drops below freezing when very cold). I am
rapidly running out of room in the house - all windowsills full!
