I inherited these plants, the one is a begonia (1st and 3rd, same plant) but I would like to know what kind and the other (2nd) I have no idea. Thanks!
Yup. Aglaonema 'Silver Queen.' Don't know on the Begonia; there are so many varieties (and some of them have multiple names) that it may not be worth the time it takes to track down a specific ID.
Possibly one of the cane-like Begonias. It might be worth checking out the American begonia Society for more helpful info. http://www.begonias.org/Articles/Vol47/CaneLikeBegonias.htm
