Observation on Pinus pumila

tsugajunkie z5 SE WIMarch 26, 2014

Pinus pumila is hardy to about zone 3 or there abouts and I always found it interesting on how it reacts to cold. This is a pic of my P. pumila 'Jeddeloh' when the temp is around 30*F.

...and here it is at about 15*F. No pine I have reacts to cold this way.

Interesting. Was it buried in snow? BTW, that's how I react to cold...

No, not buried before the pix. These were taken last fall. We had a cold start to winter before the snow started coming...and kept coming. I'm sure it does this so it can be buried and protected. Other pines will droop a bit in cold or other conditions (densiflora's needles close up in the rain) but nothing I have reacts to this degree.

I've noticed bunching needles during rain on one of my pines, why does it do that?

Pinus heldriechii needles close up to almost vertical in rain and damp weather. It needs to be quite dry for them to really spread out.

Maybe it presents less catch area to rain and prevents rot to the buds.
