This isn't a tall tale, I swear. I scarified the seed on 1/19 between two sheets of sandpaper, taking care not to damage the inside of the seeds. I then soaked them in warm water for 24 hours, and sowed 1/8th inch deep on 1/20, in gritty mix at around 55 - 60F, in ordinary indoor light. They are nearly all up tonight, 1/24.
I've sown these several times before without scarifying, and gotten almost no germination, even after several months.
You don't have to convince me... Fabaceae, especially, are amazing for rapid germination after scarification!
Rapid seed germination is a bonus for sure - on the other hand, something I've come to expect at some level. At a quick glance, some notable ones for me - 2 days for Gastrolychnis apetala, 1 day for Campanula topaliana (interesting in that many/most Campanula seem to require stratification), 3 days for Oxytropis viscida after scarification. Acantholimon seem to have amazingly rapid germination as well.
