Sorry, never got back this sooner. As of now, I have two pots of 'Gryphon' sitting in a sunny south window and they're actually looking rather good for having previously lost all their foliage and one even has some flower buds. I have yet to find this begonia available here, though I've taken in fewer greenhouses the last couple of years. Good to know they respond well to either being cut right back or doing cuttings. I have numerous plants in each pot and think I'll later do some separating and trim the tops way back to see what becomes. Your photos are fantastic as always and I appreciate your knowledge and assistance!

My tops have gone south so I cut them all off and laying in a pan of moistened soil. I can always pick up another pot this spring if I need or want any more. Guess I've been buying this begonia since 2011 going by my photos.

I think after a shower, it glistens but then so do a lot of other plants (begonias, hydrangea, and Jatropha multifida) (July 5, 2013)

I wonder if one of the parents is diadema? This was taken the same day as the photo above.

Here is another Gryphon that day along with a host of begonias and some coleus.

At one time there were two similar begonias out there - Nancy Cummins and thiemei x wollnyi and I found both frustrating to grow. Maybe the cross was named Nancy and I am thinking of another begonia of similar look. Aussie Star is another similar looking one but it comes from Australia if I recall correctly.

Yes 'Gryphon' sure does share plenty of similarities with diadema. Whatever the parentage, 'Gryphon' is a breeze to grow and copes with my on and off neglect and the warm temps and cool it's been receiving this winter.

Good Deal! If mine croak, I will pick up another one - probably. It is a great looking begonia when grown right.

Yes, they really had done so very for me, only needed shade them a bit during the hottest weather, especially as our summer humidity is low and things tend to burn.

Picked up one of these last summer and have been very impressed with how easy care it is. I brought it indoors for the winter and it is blooming nicely now. It did lose a fair number of stems and leaves, but I think maybe I kept it in a room that was a little bit too cool and did not provide enough light. Note that the leaves are darker with less variegation. Anyway, a great plant!

Those blooms make the plant look small! WOW!

Debbie, that's both a large and rather attractive bloom display on 'Gryphon'. The one plant of mine currently in flower has only produced smaller less showy green male blooms.

Hc mcdole, I'm wondering if you would know if it's possible to do a hybrid cross between 'Gryphon' and wax begonias?
