    Difficult one this - plants have a hardiness rating from H1 - H7 very hardy . i.e Sweetpeas are hardy H5 and can be planted out now , Petunias are H2 and are tender so best left until May for planting . Now I found the EGF ratings for some plants last year , but can't find anything now . Any ideas ?
