What was the first plant you grew?
For me it would be those daffodils from school (see 13 Nov), and somewhere I grew that mix of Virginia Stock and Night Scented Stock which all children seem to grow here in UK. It must have been on Dad's allotment - another delicious perfume memory.
I also remember the smell of tomato leaves. (If you like that smell too I can recommend Feuille de Tomates soap from Sarah Raven, expensive but lasts ages and it is exactly that scent.)
The soil, the colours and perfumes, the abundance....it was all very sensual and such a contrast to the streets where I lived and the back courts where I played - so for me there was a sense of magic and other worldliness about gardens and gardening that has never left me.
By the way, are you a lark or an owl?
....and did I mention the cakes in Berlin?
