So I found a T. terscheckii at the local supermarket...

Anyways you plant developed great. How tall is it now?

It's about 9" (23cm)tall now and that's getting on for three times the height it was when I bought it four and a half years ago. Girth remains practically the same at roughly 10cm/4".

It was a big boost realising that it could go outdoors quite safely, meaning that last year's growth was quite significant for a terscheckii.

I'll take more exact measurements of it in the morning and we'll see how well it does this summer.

Here's a picture of the current measurement; it's actually a bit smaller than I recalled off the top of my head there ^.
