It is sad to hear about Graham; he was a complete one-off and County Park also a nursery absolutely like no other - no room to move and extraordinary plants wherever you looked! I must have first visited when a student in London and bought, amongst others, Chordospartium stevensonii, partly because Graham said it looked dead for the first few years of its life (!), and eventually made a weeping tree with purple pea- flowers. In his 1980 price-list it is £2.50 in a 4" pot - now it is 2.5metres in the garden! A very unusual and fascinating gentleman.
