Hey all. I'm doing tall red-mokara orchid centerpieces. I'm buying them bulk from Fifty Flowers. Due to the cost of the orchids, I'd like to use a filler flower to make sure the centerpieces look full without spending a fortune! I'd like them to be a "hot" color-- preferably bright red,pink or orange and have a lot of blooms for volume. I've been looking at gladiolus, stock, limonium.... any other suggestions? i could use all the help!
