Hi gals! How's everyone doing? Hope everyone is well! 

My friend has offered to help with my centerpieces and put them together so I just need to buy the flowers in bulk. I wanted to get opinions on what kind of flowers to put in a square/rectangular vase. 
Vase dimensions 
Length: 4 "
Width: 3 ¼ "
Height: 5 ½ 
My bouquet will be a pretty simple, fushia roses and cymbidium orchids. I want to keep it similar with the centerpieces and use fushia roses to tie everything together. I also would like low centerpieces that are full. 
Any other ideas on budget friendly flowers? Carnations aren't my favorite but they are cheap. I do like spider mums too! 
Here's a pic of the vase.
