Purple wedding flowers come in many different shades, from a deep purple to red violet. Please note that many flower farms that grow flowers may classify them as "purple" - which is a totally different shade than a purple crayon. Realize that computer and cell phone screens can also be a distortion of color because of the settings.
Purple gladiolus are usually a vibrant violet color as shown below.
The flowers are shipped in dry pack, with most of the head still not in bloom. You need to allow a day or so before designing so the flowers can open up to their true beauty.
Gladiolus have rather thick stems, but that are a natural for inserting into a cascade to make a long line that draws the eye downward.
Don't skip the top part of the gladiolus that have a hint of color that will continue to open up as the bouquet is brought out into the warmth of the day.
I cut another portion of the gladiolus to insert into the upper right.
The I added another bloom on the left side in the same manner.
