Wedding stem-to-box calculator
Enter the designs your event needs - bridal and bridesmaid bouquets, boutonnières, corsages, low and tall centerpieces, arches and installs - and this calculator returns the exact stems, grower bunches, and wholesale boxes to order. It adds a 10% breakage buffer and rounds up to real pack sizes: 25 roses per bunch, 125 stems per Quarter Box, 300 per Half Box, hydrangea by the head. Quantities are free and need no login; your wholesale total shows once you sign in.
