I was wondering how late I would be able to plant Herniaria glabra plugs? Would it be ok if they were planted in mid September?

The recommended planting time is late spring to early summer.
I would recommend overwintering them if possible in a greenhouse, but if this is not possible, go ahead and plant out.
Make sure you water well and get them established before they go dormant for the winter.
