My Camelia has not flowered

Probably, look at the other questions about Camellia flowering just below yours... if you can see viable flower buds - no matter how small - then eventually it will flower.

You don't say how you are growing the shrub, it likes an acidic soil, semi-shade to almost full sun and needs protecting from frost (or you will lose the flower buds). If you have not given it a feed in a while you could top dress it with something like a Rhododendron fertiliser that you then lightly forked in or use MPK.

Hello,
It has lots of buds on it all a nice healthy size and is situated in a bright sunny position, when we get sun that is! I have recently top dressed it with some fertilizer and to be honest it looks very healthy. After i wrote my post i saw different comments on camellias am still finding my way around the site, will be patient and take some pics when it flowers, thanks for your reply.
