Happy, where in North london? B&Q in Watford is good for reducing plants. I recently bought three massive pots of achillea for £2.5 each and a nandina for £5.
Smiths Nurseries in Uxbridge is another good one and so is Flowerland in Iver (these two are not far from each other).
Van Hage in Chenies is ok.
Aylett Nurseries on the way to the Galleria is a little pricey but good for ideas.
Further afield, Butters and also Baytree, not far from Spalding are good too. I got 2 callicarpa complete with purple berries from Butters for £2.50 each.
