Success at last ,Kept 1 on my surviving the wind plant,this grew to 90cm long ,and 12kilos.
{WOW} Needed long time to get to this to ripe stage ,so had to protect from 1st cold spells.
Best baked with olive oil and spice, or just steamed and mashed with butter. Will keep seeds and try to better the size next year, friends thought we gave it hormones, but we grow only organically.

UPDATE . Grew again this year ,kept 1 specimen on plant ,took whole season to mature to 12 kilos 90 cm long [WOW] protected from cold weather until picking at mid May ,cured for a couple weeks and started eating begin June. Cut off a oiece at a time and wipe end with bleach to stop any mould and it seals itself.Am keeping on the counter in my cold kitchen .Kept seeds and am definitely growing again.Best baked or glazed in pan with oil ar butter and sugar to glaze ,,FABULOUS.

This is my 2nd season of growing this butternut ,no luck so far with fruiting .2017 season very cold until January so no female flowers ,2018 was extremely hot from early October so no female flowers and pollen inactive , only cooled now in end February ,managed to get 3 viable fruit off 2 plants ,but II don't think we have enough time for them to ripen properly . I am not giving up on this variety as I really want these . so will try again next year Good strong plants though

Mine were slow to start but now are producing very...very large butternuts. approx 5 kilogram average weight and still growing... woohoooo

These are really exciting and my family have a hard time believing that they're butternut! Although they do have a long neck, it's not often THAT long.. though the neck is very thick! Lots of flesh!
