Yeah, Stam's are great. They really know their stuff, so if you decide to take a trip there, ring them in advance and bring along a sketch of your garden showing orientation, existing planting, shade, etc. and they'll tell you what will best suit your needs. They've a great range, and will order in for you if you want something in particular. They won't rush you either, and they don't go for the hard sell (they gave me the same advice as Henny Penny when I told them I was on a severe budget).
Ahhhh... genuine customer service... *nostalgic sigh*...
