Re: Hydrangeas and temps.

> Will hydrangeas tolerate temps in the 0-10 degree range? <
Based solely on perennial catalogs I keep in the office, the answer
(because 0-10 degrees F. => USDA zone 7) appears to be "yes."  Bluestone
lists the following min. USDA zone for the hydrangea in its catalog:
     Arborescens: 3
     Paniculata: 3 or 4
     Petiolaris: 4
     Quercifolia: 5
     Macrophylla: 5 or 6
Wayside Gardens usually specifies the next zone up, but no min. zone is
greater than 6.

Hope that helps!
