It was a great idea, I'm really excited to see what plants I get, so far they are only a few mm across so they all look very similar, but I expect that in a few weeks I will start to see differences. I'm glad I can already see small flecks on the leaves, it should mean that those plants will have the silver spots that the mother plant had. What I'm really hoping for is a 3m tall hardy begonia, but I know it's more likely to be somewhere between the two parent plants, although with hybrid vigour there is a chance it could grow taller than the mother plant.
Did you do a follow-up on these seedlings? I have a lot of the hardy begonia seeds and want to grow the plant at my new home. It will be nice to learn what worked for you. Thanks!
No not yet, I have really struggled to get them to grow, I have tried various different growing conditions and compost types but all the plants have only grown about four leaves and they are still the size that you see in this video. The cross I did was between two very different begonias and I think the genetic difference may be too large for viable plants. But I am going to try it again this fall with some more closely related Begonia species.
Interesting project. I had a similar thought but with my giant cane begonia and something fragrant, possibly outdoor or a solanthera. Would love a giant cane that smells lovely when it is covered in flowers.
I think I'm going to try another cross this year as I would like to see if a tuberous begonia can be bred with a cane begonia. From such a cross I would be hoping to get a plant with the height and foliage from the cane begonia with the large showy flowers of the tuberous begonia.
I know you said that you'd removed all of the male parts of your indoor plant, but is there a particular reason that the indoor was the female and the outdoor was the male, or was that just happenstance? Would there be any differences if you reversed the sexes for fertilization?
The reason I choose the indoor plant as the mother plant was because the hardy begonia only started flowering in late autumn and so there was not enough time for the hardy begonia to ripen seeds before the frost would kill the flowers. It's hardy only at the root level and the bulbils on it's stems so all the above ground growth dies back with the frosts. Yes I would expect there would be a difference in the seedlings if I swapped the sexes although I'm not sure how big the difference would be. I could always grow one of the hardy begonias indoors next year and use it as the mother plant to see what the differences would be.
Not well, for some reason there has been zero growth over the last few months. I have separated a few and tried different feed levels, compost, temperatures and light levels and none have grown. Most are still alive, but there hasn't been any more leaves. I'm wondering if the two parent plants were too distantly related and so the genetics are not fully compatible.
@@Gardeningat58N Thank You for your reply! That's really weird 😐 I hope they'll grow faster soon... maybe they need low temperature because the seeds of the hardy one probably go through some stratification outside in the winter? Good Luck!!
@@Gardeningat58Nthanks for replying and have you tried adding rockdust or seashell grit on top of the soil because begonias love higher Ph mineral soil but this also will regulate algae and moss development which suppress their growth. Placing the separated seedlings outside around or under bushes where they'll be on shadow but with better airflow also humidity 😊

I can't believe you actually did my idea. I can't wait to see what they grow up to become!!!

@@Gardeningat58N can you do update video on this seedlings
You Always got good content, please continue like this my friend

@@Gardeningat58N make sure you save the seeds, can always sell them on!

How are they doing? 👀
