I got a chocolate biscuit. A heart-shaped, poshly wrapped one - but still, it was basically a chocolate biscuit. Oh, and three roses - but they were free from Baumax (at least DH told me, I suppose).
I wouldn't have been impressed with a lemon tree either, though - mainly because DH is obsessed with buying things for the garden so it would really have been a present to himself. And our garden is the size of a postage stamp and I was complaining to DH only yesterday that we have too many fruit trees. But your garden is much bigger so I'm sure you'll learn to love it.
