Chinese artichoke

I bought a few at a local seed fair this month for the first time - so no idea - sorry! I know places like Otter Farm sell them online: https://www.otterfarm.co.uk/product/chinese-artichokes/

They sound interesting and can be bought on line at otterfarm as Wolveryeti says. They are not expensive either; 5 large tubers for £3.90.

I have not grown them but I don't think that I have room, they are described as  sprawling 70cm high plants.

I look forward to hearing how it went 

They are expensive down here at €15 per kg and the tubers never are really that big. However today I went to the shop which was selling them and bought 15 tubers which cost about €2 I am going to plant them up in to 15cm pots and then when the weather warms up a bit plant them out. Its a bit of fun and they are said to be very good in stir fries or even pickled. They can be continued by saving a few tubers to plant out the next year. So something a bit different this year and said to be hardy enough to be left in the ground in winter too, which is said to be the best way to keep them fresh.
