Starred cultivars are those being or having been sought after for the world's largest collection (over 1,000) of hydrangea cultivars at the gardens of Corinne and Robert Mallet's "Association Shamrock". Nantucket Hydrangea & Hydrangea Farm Nursery have been effectively working closely with the Mallets to shorten this list and encourage our viewers to keep there eyes open... you never know where one may appear.
