I wanted some low ground cover plants for my aquarium so I ordered these seeds on Amazon:
Glossostigma Hemianthus Callitrichoides
They came in yesterday, April 10, 2018.
Lots and lots of little seeds. According to the instructions on the seller’s page, they should be planted on top of very wet growing medium which is maintained at 80°F and they should germinate in ten days. I have placed some seeds on extremely well-hydrated peat pellets. The water and growing medium are maintained at about 80°F.
I’ll post an update ten days from yesterday or when the seeds germinate, whichever comes first.
