How Many Flowers Do I Order? As a general rule you want 18-24 stems per table arrangement or bridesmaid bouquets. 12 stems work nicely for a small bouquet. 20-25 stems is a nice amount for the brides bouquet as well as large arrangements using line flowers. Each boutonniere is 1-3 stems, corsages are 3-5 blooms. The definition of stem here is a main flower like a rose, carnation and so on. For fillers such as babies breath a field bunch will do approx. 3-4 arrangements.
