Is the smell anything like dead badger?
I think my roses are going to bloom before June this year; the progress of the season can normally be measured to within a week by flowers:
Third week in April: cherry tree blossom
Second week in May: bluebells
First of June: roses and lupins
Third week of June: the enormous pot of lilies on our patio
First of July: honeysuckle gets going
By August it's all looking a bit sun-bleached and tired, except the roses. I always forget to plant gladioli for September.
