For over 50 years, floral foam has been the most commonly used method for stabilizing flowers in arrangements and large-scale installations. Its popularity stems from its ability to securely hold stems at any angle while keeping them hydrated, thanks to its pH-balanced composition. However, beneath its convenience lies a troubling reality.

Floral foam is made of toxic, non-biodegradable materials—containing carcinogenic chemicals such as formaldehyde, carbon black, and barium sulfate, along with plastic-based micro-particles. While it may appear to dissolve in water, it actually breaks down into microplastics and chemical residue, polluting water systems and harming aquatic life. Often, leftover foam is rinsed down drains or discarded outdoors, contributing to long-term environmental damage.

Thankfully, there are sustainable alternatives. While they may require a bit more effort and creativity, materials like Agra-Wool, OshunPouch®, floral frogs, chicken wire, woven branches, water tubes, and moss can all serve the same purpose without harming the planet.

At Rune & Rose Floral Designs, we are committed to floral practices that honor the earth. We believe that something as rooted in natural beauty as flowers should never come at the cost of the environment. That’s why we’ve made the conscious choice to design without floral foam—because sustainability should always be in season.
