Not an advert but I came across this book recently..........Heirloom Plants published by Ivy Press. Based on the seed catalogues of Thomas Etty and covers Veg., Fruit, Herbs and Flowers.
Worth a look I think
It looks fascinating Philippa - http://www.ivypress.co.uk/books/heirloom-plants/
Thanks for drawing it to our attention
Talking of heirloom veg, two summers ago I grew Black Russian tomatoes. They all became victims of blight!
