Hi Jeffrey, please could you tell us what kind of wood diid you use for this balcony? Thanks

Rachel, in answer to your question, I don't think that's Alchemilla mollis you're looking at; the leaves aren't folded enough. I think it's more likely a different Heuchera (Coral Bells), possibly one of the Bressingham Hybrids, which have plainer leaves than more recent introductions. And I think the small plants with dark green leaves are probably Ajuga Chocolate Chip.
