Yes, they look like the seeds of a species begonia, but you can't tell much from just the picture of the blossoms, whether a hybrid or a species

Rick - hello - got a new email address and lost yours - glad you got white sprite to grow and bloom for you! Hope it makes lots of seed for you too. I would take a guess that your begonia is maybe probably a Non-Stop Mocha Series or some other similar seed grown tuberous variety. Very nice looking in your pic, it will want to go dormant so hold back on the watering.

Rockdale, yes I am deep in the addiction, can you say OCD? As my late brother said about Coca-Cola, he isn't addicted to it, just loves it a lot and can't live without it. That was my excuse for begonia collecting. I continue adding to the collection although I have slowed down some as the winter space is running out and I am getting older every year. It is a labor to move them out and in every year. The ABS convention is in Sacramento in a few weeks - come join the madness. http://begonias.org/ Here is a big one that while plain green, the size and shape is worth it to me - 'Red Umbo' B. platanifolia is a big leaf, tall thick stem. The base of platanifolia shows it has caudex forming clumps. The stones are in there to discourage digging squirrels. one of the new begonias on the scene and propagated/grown by our youngest club member is B. cleopatrae some rex like begonias and a propagating tray using Jiffy pellets - I must pot these up to a proper pot one of these days. don't forget the hardy begonia - B. grandis a few begonias scattered about this willow oak. backing up a tad or zooming out No name but I couldn't pass it by years ago. Sometimes I combine plants in the same pot.

Bernie, Your leaf of Maurice may root but I kind of doubt it will make a plant. I had a leaf of some superba type canes (Sophie or Lana or maybe Irene) that rooted but never produced a plant. There was a grant from the ABS many years ago to a college botany study to see if there was a secret to obtaining a plant from a cane leaf - never happened. I wonder if tissue culture would work but I seriously doubt that too. The odd thing is some Asian cane looking types can be propagated by leaf such as amphioxus and brevirimosa. Go figure. I have all my begonias indoors now and looking halfway decent. back corner of the big utility room with many canes. Valida is the leaf floppy shrubby begonia. Mr. Hunt is too tall to fit under this light Taconite is the big leaf and Shaun's Dream is the green curly leaf rex my aconitifolia is nearly six feet tall. The cane is Comte de Lesseps. Virginia Jens is a big honking begonia. Judy Cook is a big rex like begonia My own seed grown maculata hybrid Syngoniums and a cane called Hazel's Front Porch in this aluminum pan (been in the same pan for years) Here is the newest stem coming up in the pan.
