Geum are new to me as well, I've seen them in catalogs for years, but hadn't seen them growing anywhere close. Tried one from a greenhouse a few years ago, but it didn't last long. I lived in a moist, woodland setting then, so that was probably the reason. I received some seeds from a swap this year and wintersowed them with no expectations. They germinated just a few days ago, so this will be a fun experiment.
