Don’t worry about cutting your stems to size while you’re out in the garden; it’s best to wait until you’re back inside and have your vase or other container in front of you. Depending on your vase or type of wildflower, there are several ways to size your cut flowers. Flowers with big heads (like Sunflowers) need a tall, sturdy vase or container to keep the heavy blooms supported. If you’re doing a large bouquet with a variety of different wildflowers, you’ll also want to use a tall, sturdy vase. If you have shorter flowers with smaller blooms (like Cosmos or Bachelor Buttons), you can use a short vase or even a bud vase to create your arrangement.
Place each stem on the surface next to the vase to estimate how much of the stem you'll need to cut.
The wider the opening of your vase, the more flowers you’ll need to get a full look. A tall, sturdy vase with a narrow opening can look full with just a few Sunflower stems. The same size vase with a wider opening may require 6-8 to look complete.
Stand each flower up on the surface next to your container to see how tall it will look and then use that estimate to cut your flowers to size. Remember: flowers can always get shorter, but they can’t re-grow! Always err on the side of caution when making your cuts.
The size of your container and the width of the opening will determine how many flowers you'll need for each arrangement.
