Curious-looking specimen

I find myself in possession of this. Best guess?

 

Hi @Ed S ,

It's Lisianthus ( also called Eustomis ).

It's an annual ( planted from seed every year ) and is grown mainly for the cut flower trade. If you've grown them yourself, well done as they are quite tricky to get started.

They really want planting out now and being supported by small canes.

I can't upload photos from the net on my phone ut if you have a look they are really nice .

 

Hi @KFF I thought lisianthus had pairs of leaves perfoliate. This seems to be alternating leaves...

 

With the alternate clasping leaves, it's got a slight tricyrtis x tradescantia look!
More photos of the flowers when they open please

 

Thanks, team! I'll see whether I can keep them alive long enough!
