Rhododendron leaves curled from the cold |
From Suzanne:
The other night I saw 4 muskrats at once in between our houses. They would get food and bring it back and all climb on the log and eat. There were four at once on the log. (Just before dark)I want to see that! Gotta hang out down there more in the late afternoon.
Dear Rhododendron observer,
ReplyDeleteThe rhododendron leaves will begin to curl at about -.5 C and become completely curled and pendant at -3 C. +/- Rhododendrons and their broad leafed evergreen cousins the laurels are beautiful ancient plants dating back to the pleistocene era. They have thermotropic leaf movements the reasons for which are not fully understood. Some believe that it an adaptation to prevent moisture loss. Others feel that the drop and curl of the leaf prevents snow damage to the leaf itself. Another theory holds that the curling and dropping of the leaves protects them from membrane damage due to solar exposure during cold temperatures and frequent freezing and thawing. In any event the natural world in all of its manifestations is an endless wonder, the observation of which is a yoga practice in and of itself.
