Here in Victoria, we grow a beautiful primula of uncertain name, with white flowers delicately shaded with pink around the petal margins. For many years it was locally called 'Appleblossom'; more recently, a local primula enthusiast visiting the UK came to the conclusion that it is properly 'Harpur Crewe'. However, I have been unable to find any evidence online that there is such a primula.
The growth habit of the plant resembles P. allionii, but it's not at all sensitive to overhead water. My specimen spent this last winter outside fully exposed to the elements and didn't turn a hair — if anything, it's happier than ever.
A photo is attached.
Can anyone reading offer an informed opinion on the true identity of this beautiful primula?
