Whitney's Apricot

I am trying to write confidently that this beautiful rhododendron is a Whitney's Apricot. That's what the label said - but with its bargain bin origins, can I be sure?

Are You Really Whitney's Apricot?

I guess I lose confidence when I look at the very creamy colour of the flowers. There are three of these bushes - they were all ridiculously low in price, and I think I fell in love with the name. They immediately started growing well in the mixed planting at the back of Middle Garden.

There is a coloured flax which creates an inspired backdrop for these rhododendrons to show off their subtle colours. But therein lies the problem - I'm not convinced that 'apricot' is the correct colour description. Is there such a rhododendron as Whitney's Cream?

So forgive me, and please write to me nicely, if I've seriously got the name wrong. I think I need to buy a decent New Zealand reference book...
