Maybe this can help!

Here is a link that might be useful: Gloeiosa Lily

The old T&M database says 30 days @70-75, 1/16" deep in a peaty mix. It doesn't sound like they would benefit from colder soils, maybe Spring sow?

You know, I didn't even ask, did you mean pot and put out the tubers or sow the seeds....

I'd say no WS to the tubers. Above is for seeds.

It's seeds.

I wonder if they might bloom this year if I spring sow them?
