Alchemilla Mollis has the most beautiful foliage for much of the year and then luminous yellow/green coloured flowers start to appear in July time. I’ve seen this grown in rows or stand allow. They’re great companion plants (especially with ground cover plants). They’re also brill as a cut flower!
Not much care is needed. If deadheaded they flower for longer. They will self-seed or can be divided easily if you want to build your stock!
