Q. What goes from green to brown instantly when placed in the hands on an engineer?

A: (JSJ) I suspect that's Kevin asking and he hasn't even seen  my skills with a green thing...
Here is a very pleasant pink heather on the right in October 2008...

and here is the plant on the right of the picture (from the other side of the track) a couple of weeks ago:

Oh dear, not a pretty sight.

So last weekend it was out with the old and in with the new.

And unfortunately the thyme I brought home with me after your first open day Kevin is, err, no more. The Mind Your Own Business is doing OK though. I bought one pot of it and it has now spread enough for me to be able to rip some of it up and transplant. There are those who would not believe I actually introduced it into my garden.
