There are many types of Begonias. Begonias as a rule prefer a well-draining soil and hate being overwatered or sitting in soggy soil. They aren't fond of being in a pot that's too big either. Mealy bugs are a begonia grower's biggest problem; the plants are quite prone to them. Rubbing alcohol takes care of mealies very effectively. Humidity can be an issue as well, especially for those of you who have forced air furnaces. Cane and Shrub types respond well to a daily misting. I mist my Rhizomatous types, too, always being wary of mildew.

Cane begonias are quite often referred to as angel wings. They are one of the easiest to care for in my opinion. They require filtered sun all day, although in winter here in the north I keep them in a sunny south window.

Shrub begonias are another relatively easy type. I like using them in hanging baskets, mixing a few different types for a nice contrast in leaves. Mine do very well in summer in bright light. In the winter I put them near a sunny window.

Rex begonias are the most difficult of all that I've mentioned. For the showiest foliage and colour combinations choose these. They require more humidity than the other types of begonias, therefore making them perfect for a terrarium. They do not tolerate direct sunlight and they are not heat tolerant either.

Rhizomatous begonias; proper watering is the key here, since the rhizomes are in contact with the soil rotting is a common occurence. It's a nice low light begonia.

I've purposely left out the Tuberous types. They require winter dormancy which is a whole other article.
I hope you'll think of Begonias the next time you're looking for a new house plant. They may be a bit fussy in the winter indoors, but they will survive and in the summer they shine!!
Many, many thanks to plantladylin for the use of her beautiful photos!! They make me want to move to Florida :)
