Vinca and White Delphiniums

Salvia nemerosa 'Ostfriesland' or S. 'Caradonna' - both a lovely deep purple with long flowering seasons as long as you keep dead-heading! They would be the right (medium) height and echo the spires of the Delphiniums.

Thanks. I'll look up both of these suggestions and maybe put them on my plants wanted list.

How about some Alchemilla mollis near the front, too? Its greeny-frothy flowers and rounded leaves would make a wonderful contrast. Or you could grow some green Tobacco plants from seed or plug plants (annuals) and plant them in between.

Thanks a lot! I'm now spoilt for choice!

I am looking for Asphodelus acaulis. Can anyone help me please.
