David: the lichen looking stuff is a dormant hardy sedum,at least I believe its dormant.Lets face it there are surprises around every corner.
I went to the garden center and bought 2 five gallon buckets of " Rock Garden Soil mix " its really nice to buy it that way when you only have a few planters to fill.
They also sell it by the yard.
I bought 2 new hypertufas small round $8.00 troth $10.00
The red rectangle ready for Wild Ginger order.
Armeria, Yarrow King Edward plus Mt Crest Semps.
