Lets also not forget that the heritage varieties by nature are not hybrid seeds which means that seed can be kept from the plants and planted the following year.
If you take most commercial seed stock it's hybridised resulting in the seed stock being tied to suppliers and not being replantable.
without trying to sound like a paranoid nutbag from abovetopsecret.com, the latter is a serious risk to the food chain. The moment someone allows hybrids to be patented, we all starve. Monsanto are actively working on this.
I've been growing about 200kg a year of non hybrid heritage vegetables for about 10 years in the London suburbs. Totally different to the crap they sell in the supermarkets.
