Begonias at the Atlanta Botanical Garden

This is parviflora - may be the tallest begonia ever?

maculata is fairly new there but still around 8 feet tall.

Other begonias in the same glass house.

Last one - this reminds me of photos I've seen of angularis but not being acquainted with that particular begonia I can't definitively say it is. This was in the rear and I don't think the garden would approve of me walking over their well tended gardens. This looks like it will be a very large begonia itself.

Oh wow, loved that last one, now I am going to have to look up angularis.

I think it is a parent of Grey Feather which is very easy to grow.

I should show some pictures of the elephant ears growing there. One called Malaysian Monster is indeed a monster (about twice the size of the ones I saw at Hawaii Tropical Botanical Garden last month).

I hate it when they don't label stuff in a botanical garden as opposed to being mildly annoyed when they put the plant label somewhere where I can't see it clearly. In their defense, I am totally nearsighted and need pretty big print in the back row.

BTW These begonias are great!
