So I will start where I am with Heucheras.
Last year in the 2022 season I started several from seeds.
This year I started another tray.
Mine are all from "mixed" seed packages.
These are grown under lights.
Hoping for a mix of colours for shaded spots in yard.

I really should try some from seed it has been awhile, but seem to always get an olive green color. They used to grow so well on my property but the last few years they have not been doing well.
