Your own hand tied bouquet doesn't have to have the same flowers. You have a lot of choices in bulk wedding flowers and discount greenery that I sell in individual grower bunches. This allows you to mix and match. Here's just a general guideline for this sample bouquet, but feel free to mix in different colors, flower varieties and greenery.
Quite frankly, I usually try to convince my brides to create a "mock" hand tied bouquet. I have many tutorials for creating bouquets on a bouquet holder (which gives those live flowers a much needed water source that extends their life greatly) - but understand that some prefer the traditional hand tie with no water source. This bouquet contains Oriental lilies - a great favorite with brides because of their lovely large blooms and tantalizing heady scent.
Unfortunately - these exotic lilies are very water loving and will begin to droop if in a heated area without a continual water source. Keep hand tied bouquets in a vase as long as possible before going down the aisle and replace in the vase directly after photos so to extend the life of your expensive bouquet.
Flowers that don't hold up as well in a cut bouquet design (without a water source) is garden roses, peonies, hydrangeas, sweet peas, freesia, callas, Gerbera daisies and viburnum. They all are very thirsty flowers and wilt quickly or show signs of stress.
On the other hand, daisies, standard roses, alstroemeria, chrysanthemums, seeded eucalyptus and carnations are all long lasting flowers that hold up best in a hand cut bouquet.
