Thanks anyway thewoodle, but I've checked the varieties you have and they are not what I'm after.
Danimas, Rocky, Pepita, Zeina are the ones I'm looking for, but I guess I'll just have to buy the 4 plants I need from the garden centre this year. They won't cost more than a packet of mini cucumber seeds!! A pity they are all F.1 varieties or I would have saved some seed this year. :(.
