Marrow seeds

If the seeds have reached the same size as those you originally sowed, there is every chance they will germinate after careful drying and storing in a cool, dry, place.

If they were an F1 variety they probably won't grow true to type from saved seed, and even if they weren't F1 but were grown anywhere near other cucurbits (squashes, other courgette varieties) they are quite likely to have cross pollinated with them, again giving unpredictable results.

What variety were they Rocket man?

Is that for real.............it's a must have if it is 

Not sure it woukd be worth saving if they were an "epic fail" . Might be worth getting some more prolific seeds

I think the failure is more to do with my inability to grow stuff
