Hi,

A couple website that have great information for cutting hydrangeas as cut flowers.

Annabelle makes a great cut flower for me with no extra treatment, lasting a week.

Thank you jhanifan - this does happen occasionally to me and I will try the hot water method. I also let the water dry out in the vase - and the results is usually dried blossoms. Sometimes they root in the water and I cut off most of the stem - leave a node or two and plant in potting soil and you may have a new plant in a month or so.
