Has anyone grown Begonia Rex?

I have three of them from Dibleys. I have no idea how they're still alive as I put them through the wars last year. They're growing again though.

I'm having trouble with one fine leaf one, Begonia Rex 'Connie Boswell'. I had it in a West window that gets full sun for a good few hours. One leaf this week half died and a new leaf's fine points have gone crispy.

I know they like a fairly humid atmosphere but do you think this is more likely to be leaf scorch? I've moved it to a full shade pet of the room, out of direct sunlight but near the window so still gets bright light.

Sorry Jack can't help you as I haven't grown the above but oddly enough I just bought my FIRST ever begonia " Angelic " purely because she is scented and supposedly buzzy friendly so fingers BUT my question to you my friend is what part of the continent are you living FULL sun and HOurs of it ...I need me some of that

 

Only googled the name to have a look/nose at it and this came up .."Begonia 'ConnieBoswell' (Begonia rhizomatous hybrid) Majestic in stature, this upright grower performs well in an east or west window in partial sunlight." if you click under plant care it also says about humidity/temps etc. http://www.logees.com/begonia-connie-boswell-begonia-rhizomatous-hybrid.html

Pretty plant btw! I only grow tuberous ones with big blousey flowers, might have to expand my varieties.

 

Thank you, that advice looks very clear to me. I know the room's humidity is higher than that, so it must be over exposure to sun and scorch :-/

 

I grew one many years ago, I seem to remember good light rather than direct sun.

Also very easy to over water.
Other than that, cant help much.

 

I have had some success with them in the foliage plant class at a couple of local shows. You are right about them needing fairly high humidity. Seeing as I grow my tomatoes on wet gravel using the ring culture method, the Rex Begonias do well stood in-between the tomato plants. I have also found that they do better in half depth pots.

 

Thanks both. I'm going to try moving one to a shady part of the room to see if I can stop the leaf tips crisping up. If that fails, I guess it must be the humidity.

When grown in the house its usually recommended to stand them on a tray full of damp gravel, or better still keep them in the bathroom.
