I haven't ordered any seeds from America but I have considered it for pumpkins. Given growing huge pumpkins can be quite competitive over there I once found a number of sites selling seeds from true (Altantic) giants. From what remember these came it at up to $20 per seed from 1500lb-ers and the price decreased as the weight reduced. Just shows what a kiilling you could make if you successfully grew one! I just thought how gutted I'd be if a slug got it first
Maybe somebody will be tempted trying to win the GYO 2008 biggest pumpkin section?!
