...and more seedlings

Several minute seedlings have appeared behind and to the south of the sallow log, bringing the total number for WBX up to seven. I wonder if these newcomers might be heathers the seeds of which could have survived in the John Innes soil, or (more likely) pearlwort, Sagina procumbens.

It is cold again and nothing grows very quickly, so it will be some time before I find out.
