The tree peony will definitely be worth the wait! I moved into my current house here in Surrey last Autumn and directly by our front decking was a large shrub I'd not seen before, with a lovely red stems and big, bold, beautifully textured leaves - I had no idea what it was (being new to this gardening lark). This Spring of course, the magnificent yellow flowers sprang to life and I found out what the plant was - couldn't believe the stems would actually hold the flowers up they were so large!
