This is Cucurbita pepo var. giraumontia var. Warszawska.
Common names: vegetable spaghetti, noodle squash, Spaghetti Marrow.
I grew it for the first time and as I result have some extra seeds, that I may swap.
This spaghetti squash can be stored for use during the winter.
Seeds do not germinate in cold soil, so it is better to sow the seeds on the windowsill in colder climate.
Plant grows up to 5 m long. 1 plant may grow 6-7 cylindrical fruits of maximum size 1,5 kg.
If you are interested, let me know by e-mail, which is available in profile section. I will be more than pleased to send it to you. No extra charge.
I have received lately some amazing tomato seeds from
Patrick at Bifurcated Carrots. If you drop there, you may read very informative post about why swaping seeds is important.
