Don't know of a cultivar name beginning with "Hur".There is one that begins with a "K", called; 'Kurohime'. It, like most H. serrata's, can have pink to purple flowers when grown in neutral to alkaline soil. There is also 'Kurenai', but it has white flowers.

Here's a link to Dave's Garden website that has a listing of Hydrangea cultivars.

Could it be Miranda?
