In today’s floral industry, the conversation around design mechanics—whether using traditional floral foam or foam-free alternatives—has never been more relevant. Floral foam has long been a trusted staple for event work, centerpieces, and installations, while foam-free options are opening new doors for creative expression and sustainable design. At 46 & Spruce, we’re here to guide you through the differences, so you can choose the mechanics that best fit your needs, your budget, and your values.
Floral Foam
Floral foam is a synthetic, water-retentive material that holds stems securely in place while keeping flowers hydrated.

Why Florists Use It:
- Stability: Locks stems into place and allows arrangements to travel without falling apart.
- Hydration: Keeps blooms fresh during long events.
- Accessibility: Affordable and widely available.
Floral foam certainly has its place—especially when creating intricate event centerpieces or when stability during transport is essential. But many florists are looking for sustainable alternatives.
Foam-Free Mechanics: A Sustainable Shift
Foam-free floral design eliminates single-use foam and instead uses reusable or biodegradable mechanics. These mechanics not only reduce waste but also open doors to more creative and airy designs.

Benefits of Foam-Free Design:
- Sustainability: Reduces microplastic pollution and supports eco-friendly practices.
- Reusability: Tools like grids, chicken wire, and floral frogs can be used again and again.
- Creative Freedom: Natural structures (like twigs, vines, and moss) and innovative tools encourage new design techniques.

Holly Chapple Egg®: Locks stems into place for professional bridal bouquets and handheld designs. Perfect for achieving width, height, and cascade while minimizing flower use.

Holly Chapple Installation Mechanics: Combining the Pillow® and Egg® systems with water reservoirs, these reusable armatures can be affixed to arches, arbors, or chuppahs for stunning event installations.

DIY Floral Grid: A reusable, interlocking grid that holds stems securely in vases. Simply remove after arranging for easy cleanup and repeat use.
The Bottom Line
Floral foam continues to be a convenient and budget-friendly option for arranging flowers, offering reliability for event work, centerpieces, and everyday designs. Foam-free mechanics, on the other hand, provide florists with an opportunity to explore sustainable techniques, spark creativity, and meet the growing interest in eco-conscious design.
Sustainable floristry isn’t just a trend—it’s the future of design. From weddings to events to daily arrangements, foam-free mechanics open the door to innovative approaches that align with evolving consumer values.
