Hi Tigermad - if it's getting the full force of the midday sun just now, it's probably just a bit of sun stroke! I have one which was planted last year in a very sunny spot and it was suffering in the same way. I've moved it to the other end of the bed it's in, where it doesn't get so much sun until the afternoon, and it's much happier. It still gets loads of light, but it's a bit more protected. There's a few 'airy' plants in front of it too which also helps. If you can't move it to a place where it can get a little bit of shade through the hottest part of the day, you could perhaps put a couple of pots in front of it fro now, or even erect a simple bit of shading with some canes and light material. Once it's a bigger shrub, it'll be able to withstand it more easily. Just make sure that it's getting enough water too, since it's quite newly planted.
