Oh that's lovely! I already bought railing beds for my herbs but maybe next year and I'd have the perfect spot for it too. I love Pinterest, I swear if I could make a living out of browsing on there I would. I'm going to have to keep an eye out for old wheels this summer, maybe at garage sales or something of the sort. As for herbs, I'd like to know what kind of herbs people plant? So far I've got basil, savory, rosemary and lemon grass. I've heard of lemon grass warding off mosquitoes, any other herbs/flowers known to do that?
