I'm not sure how much you want to spend but these watering cans from BHS are so cute! http://www.bhs.co.uk/mall/productpage.cfm/bhsstore/953248/232809
These are green glass vases from Dunelm - only £10 http://www.dunelm-mill.com/shop/key-lime-collection-glass-hurricane-vase-168023#5050210686636
I also saw this jug and thought it was pretty - it's got a bit of green but also pink roses if that ties in with your theme at all http://www.dunelm-mill.com/shop/parisian-collection-floral-jug-60022?utm_source=google&utm_medium=googleshopping&utm_campaign=gshopping
Hope you find something you like!
