Steve...more on the Heliopsis helianthoides. Is it a named cultivar (looks like 'Sommersonne' aka 'Summer Sun')? Are you growing it for seed, stems, both? I'm curious because I started 4 different Heliopsis this year. 'Loraine Sunshine,' 'Summer Sun,' one described as "yellow double" and one described only as Heliopsis. I had great germination in all of them, and am wondering what to be ready for.
