'Bonita Shea' stays on the smaller side. This photo will give you an idea of what it looks like in a standard hanging basket.

According to some, it may be the same variety as Manaus, U002, and 'Amnesia' but I don't claim to know.
My 'Bonita Shea' came from the University of Georgia Trial Gardens and it has tested well there for many years. It used to be part of the "Athens Select" collection of plants (before that line went defunct. )
That crowded look of the leaves is normal for this plant. It can tolerate more sun than many Begonias but is good in part shade, too. It is heat tolerant. Like most Begonias, it doesn't like to have soggy roots. It likes a moist, but well-drained mix. Overall, it is a very easy plant.
I started my cuttings in a peat/perlite/vermiculite mix but perlite and tent should probably work fine.
Yes, you can overwinter it inside over the winter.
