Red, white and blue are the colors of Independence Day, so here are some suggestions.
Sun
Blue angelonia (Angelonia) or blue salvia (S. farinacea), surrounded by red petunias. Use a white fan flower (Scaevola), Snow Princess alyssum (Lobularia) or Diamond Frost (Euphorbia) as a trailer.
Shade
Red dragon wing begonia (Begonia) under planted with white impatiens (Impatiens). Use Summer Wave Blue torenia (Torenia) as a trailer.
Here are some other patriotic plant suggestions from Proven Winners. Most of these are still available at area garden centers.
