Alright everyone, it's been a long time since I posted anything, but then again there was little to post about Sticking tongue out Up until today still nothing has happened with the germinating seeds. I've been searching on and on on the internet looking for a blog, forum post or article about someone else who tried to start these from seed, but came up empty. I even contacted a botanical garden in the Netherlands whom I knew had Hymenocallis in their collection and would sure also be propagating these.
They indeed stated that these plants first form underground bulblets and take a resting period before starting leaf growth. Funny thing, before replying they sent me a link to MY OWN article on this forum on how to start germinating these Hilarious! *surprise!*

Anyway, I continued my search and today I stumbled upon an article about propagating lilies by seed (they're quite closely related) and I came upon a specific term that really described my 'situation' and evolution of the seeds up until now namely 'hypogeal germination' :

Don't now whether - as stated with the variations on the germination - they also need a colder period or just continue to be warm. To find out I placed about half of the bulblets in the attic where it's around 10°C and can be brought back to a warmer room in spring, the rest stays in the living room (I really needed to have set up a diary on this to describe my findings Blinking ) Anyway, we'll see how it goes and I'll continue to share my findings on this forum for anyone interested.

Here a photo where you can actually see the little bulblet forming and emerging out of the seedcoat. I noticed they form really shallow, right beneath the soil level and pull themselves down deeper.
