I bought this as an itty bitty Goji plant around a year old from Sainsbury's. I was impressed that they even stocked them! Well, since my attempts to grow them from seed were unsuccessful this year I thought, "Why not?" even though I find it much more rewarding to eat from something I grew myself entirely from seed.
This has come along really well, it seemed to barely do anything over the summer, and now that Autumn has hit, it has shot side branches out all over the place AND its also grown super tall, way past the 1m canes I have for supports. Hoping for some flowers and berries next year from this one.
