I like
Sarracenia rubra flowers. Grass Pink Orchids (
Calopogon sp.) too! These two are great bog plants that bloom pretty shades of red, purple, and pink! Grass Pink even features white!
Hibiscus lasiocarpos is an awesome plant that loves to have it's feet wet. It has very large and beautiful flowers with a stunning red center surrounded by a nice shade of white/pink. I've wanted this plant for a long time but I've never been able to get it.
All of these plants are awesome bog plants that can grow right alongside CPs all year round (that means they need dormancy too). They are very pretty plants and make bog gardens shine. I'd allow some room between these guys and others as they are space hoggers and love to make babies. Great plants, nonetheless.
