I have had this for coming upto to 3 years now in a 12inch pot on our
patio, and the picture on the label shows loads of blue flowers.
For the first 2 years there were no flowers at all,and this year there
is just one solitary purple ish flower.

Is this normal or have I missed something, like putting it in a border??
Thanks

Blue-flowered rhododendrons exist only in the minds of their sellers and
their photoshopped catalogues. There are *no* blue-flowered rhodos.

When very young, rhodos do not flower. You don't say how old or how big
yours is. Now it has started flowering, it should do so every year, and
you should get increasing numbers of flowers. A 12 inch pot should keep
it going for several years, but eventually it will need repotting. I've
not tried giving rhodos fertilisers; maybe someone else in this NG has
more info on this aspect of growing them.
