Moss on Northern Sunny Side

As we approach the summer solstice the sun has so much north in it that no side of buildings, trees or other exposed areas will stay in the shade all day.

This is a northern roof getting a good late afternoon roasting. The moss, which in mid-winter is a plump dark green is in full retreat at this time of year. It is well-established and will survive until the sun starts moving south again in three weeks.
