Laura: I agree, that pretty potted plant is an Azalea and it does indeed look like there might be two different plants in the pot. As SongofJoy stated, they like acidic soil. Tell your daughter that she can dig a bit of coffee grounds into the top of the soil when she plants them ... azalea's love the acid that coffee grounds provide. Here's a link with information on the Encore Azalea's:

Tee: Those Azalea's in your garden are beautiful! I miss having Azalea's. For many years we had huge ones all around our home ... some were transplanted elsewhere in the garden and a few were lost to hurricanes one year when two large trees fell on them.
