The hardiness of Sinningia leucotricha in the Atlantic States is 
remarkable - everything about it appears to scream 'not hardy'. I shall have 
to consider whether or not to risk one of my old tubers here...

I greatly admired Tony's Hemiboea when at Plant Delights Nursery last year, 
as well as several other Sinningia spp & cronies e.g. Titanotrichum. They 
all clearly need experimenting with over here, but my suspicion is that many 
will find our summers too cool for their liking.
