My favourite Sweet William ' Sooty' had lots of seed pods if (gorgous dark flowers and ' dark chocolatey' fragrance. Also the deep wine coloured variety, also fragrant. They self seed, so if someone likes SW's.......or swap for different types?
Same with Astrantia, white with palest pink tinges...I love it. Anyone got any other types?
Not ready yet but will have Hollyhocks; pale lemon, pale pink through all shades to deep red.
