Thanks everyone for your suggestions and advice!
Charleen - Your lush brugs is what I want mine to look like. More foliage along with the blooms. The foliage is pretty scarce on mine. Maybe I am not fertilizing enough.
Yes! The blooms do start off white and then change to whatever color they are going to be.
Brenda - Good idea about shading the pots with other plants. I have most of my brugs growing in sun half of the day and the other half in shade from a large Oak tree. I know from past experience that the sun and heat is too harsh for them to get direct sunlight all day especially in summer. The good thing about containers is that you can move them when necessary!
