Chaenomeles japonica 'chojubai' - "chojubai quince"

[GorrilaGardener]

Anyone know where I could source seed or cuttings of this beautiful plant? 

 

There is a chaenomeles at my tafe that I believe to be 'chojubai', in saying that I need to get a picture next week to verify taxanomy. But it has white-pink flowers. Anyone know if pink is a form of 'chojubai'?

 

any help appreciated
