What is the proper angle for cutting flowers for a boutonniere?

Cutting flowers for a boutonniere at a 45-degree angle is recommended because this technique increases the surface area of the stem that is exposed to water, which helps with hydration. The slant of the cut allows for better water absorption and prevents the stem from sitting flat on the bottom of a vase or boutonniere holder, which can limit water uptake. By using a 45-degree angle, you're also less likely to crush the stem, preserving the flower's overall health and longevity. Proper hydration is crucial for maintaining the freshness and appearance of the boutonniere until it is worn, making the angle important for both aesthetics and practicality in floral design.
