onion simiane

has anyone out there been growing an onion called simine there a torpedo shape onion listed in Moles catalogue as long de florence simane  and in Kings as Rossa longa Firenze I think there basically the same onion I have grew simian in the past but never seem to have much luck growing them maybe I was doing something wrong so I'm going to give them another go next season if you have been growing this variety any info would be much appreciated RW

thank you for your reply Mum  can I ask do they get very big and are they a sweet tasting onion ? also I'm going to follow your advise by sowing the seed in modules in the greenhouse come spring do you pot them on into a larger pot before planting out or plant them out directly from the modules in the ground and do you feed them once planted  or prep the ground prior to plantings with say a balanced fertilizer?

thanks for your reply Mum will give them a try next season having ordered the seed once again many thanks RW
