This one popped up in one of my containers, I'm curious about it because of the unusual leaf shape, so I gave it its own pot..
For a moment I thought it could be Hippobroma longiflora;
Star of Bethlehem (Hippobroma longiflora)
But then this seedling doesn't seem to intend to form a rosette..

Perhaps an Isotoma axillaris (aka Laurentia axillaris) seedling?

You got it!
I have had Isotoma axillaris the previous years, never grew them from seed though, so didn't recognize.

Danita

I love that plant. It's so cute and blooms constantly.
Thanks for the tip!

I just looked up the pictures in the plant database--what a pretty plant!
