Can I start sowing onion seeds in November. If so which type of onion is suitable

One last thought .... I never seem to get everything into my first response ==> Egyptian walking onion --onions and other alliums need more phosphorus and potassium than most other vegetables. They also need more copper, manganese, zinc, and molybdenum- however most of these are adequately represent in compost. BUT, if you have any issues, and it is unlikely that you will with walking onions --- but if you do, first thing I would do is ensure all of these elements are present (in Canada our "old" pennies have a lot of copper, we just add this obsolete currency to the garden). Molybdenum is found in wood ash (just the stuff from the fireplace, firepit or wood burning stove -- provided you have burned "clean wood" )-- probably lots in leaf compost, and banana peel compost)-- of course potassium in potash etc.

Tree onion (Allium x proliferum) also known as Walking Onions, Egyptian Onions, Topset Onions are a perennial onion. They are part of the Alliaceae or onion family and is a hybrid of the common onion (Allium cepa) and the welsh onion (Allium fistulosum). Tree onions are the easiest of the onions to grow coping with 40-degree heat and frosts. Check out his video -- https://www.youtube.com/watch?v=olOrA80C40s -- variety matters -- and DURATION in the soil -- my understanding is harvesting too early results in low yields -- so wait for the 3rd set of topsets before harvesting as per the video. These onions take longer to get going, but are very reliable and topsets, mean you can always propagate (which is a nice to have -- since future generations get stronger and better suited to your climate).
