I *love* this clematis. 

It is called Clematis vitacella ‘Alba Luxurians’ and is indeed, to my mind, luxurious.

It’s not the ‘in your face’ Clematis jackmanii, although I love the rich colour of that hybrid, or any of the bright bi-colours that look so striking from afar.  This clematis is the epitome of subtlety and grace.  With blooms that defy predictability — sometimes with four petals, other times with three or five, beautiful black anthers and splotches of green at the petals’ tips — I love their ease and simplicity.

Never needing pruning and always reliable for a good show, even in part sun (or even considerable shade), this July and August blooming clematis is worth waiting for.  And certainly worth searching out.
