I have currently got some H.C. growing in my pea gravel (poor choice I know, but it went in last year before I knew anything!). Whilst it is growing I wouldn't say it is managing to root into the gravel that well.
Is there anything to suggest which may be better suited? I have JBL AquaBasis Plus beneath the gravel so it isn't all bad! Not too keen on using riccia on slate/stone.
