Flowering Perennials

I'd love more different perennials, like:

• Low: Geranium 'Dreamland' or 'Rozanne'

• Groundcovering: Epimedium rubrum or hostas

• High, like hollylock, foxtail lily or foxtail flower

• Ferns, like ostrich fern or wood fern

Thank you for an excellent library already! It's amazing <3
