Hi .... You might check the Thompson and Morgan catalog. They offer seed as well as plants for this selection . It is listed a Geranium pratense striatum 'Splish Splash' (8 seeds for $4.49). I got the seeds this year and got 4 to germinate but only 2 actually made it to the garden. (another person I was talking to had 4 germinate and only lost one. ) They did not bloom this year so I am looking forward to seeing them in full array next season. Hope this helps.
