FAQ: What is the difference between steel and brass flower frogs?

A flower frog (also known as a kenzan or floral frog) is a reusable flower arranging tool designed to hold flower stems securely in place. Both steel pin flower frogs and brass pin flower frogs perform the same function, but the pin material affects strength, durability, corrosion resistance, and the types of flowers they're best suited to.

Steel vs Brass Kenzans: Which Flower Frog Is Right for You?

Whether you're creating an ikebana arrangement, designing wedding flowers, or looking for a sustainable alternative to floral foam, choosing the right kenzan (also known as a flower frog or floral frog) can make all the difference. While both steel pin kenzans and brass pin kenzans are designed to hold flower stems securely in place, each offers unique benefits depending on your arranging style and the materials you use.

What Is a Kenzan?

A kenzan, often called a flower frog or floral pin holder, is a reusable flower arranging tool made from a weighted metal base fitted with upright pins. It anchors flower stems without the need for floral foam, allowing you to create natural, open arrangements with excellent water access and longer-lasting flowers.

Kenzans are widely used in ikebana, the traditional Japanese art of flower arranging, but are equally valued by professional florists, event stylists, and home flower enthusiasts for creating beautiful, sustainable floral designs.

Steel Pin Kenzans

Best for: Professional floristry, structural arrangements, heavier stems, and everyday use.

Steel pin kenzans are renowned for their exceptional strength and durability, making them an excellent choice when working with thicker flower stems, woody branches, foliage, and structural botanical materials. Their rigid pins provide outstanding support, making them a favourite for demanding floral work and high-volume professional use.

Benefits of Steel Pin Kenzans

  • Strong, durable pins provide excellent support for thick, woody, and heavy stems.
  • Ideal for structural floral designs and larger arrangements.
  • Suitable for everyday professional floristry and frequent use.
  • Excellent for branches, foliage, native flowers, and heavier botanical materials.
  • Long-lasting and reusable.

Things to consider

Steel is incredibly strong, but like most steel products, it may develop light surface rust if left sitting in water for extended periods. Rinsing and drying your kenzan after use will help keep it in excellent condition for years to come.

Brass Pin Kenzans

Best for: Ikebana, everyday flower arranging, fresh flowers, and long-term corrosion resistance.

Brass pin kenzans are highly regarded for their natural resistance to rust and corrosion, making them an excellent choice for arrangements that remain in water for extended periods. Their durable brass pins securely support almost all types of fresh flowers and foliage, making them a versatile option for professional florists, floral designers, and hobbyists alike.

Benefits of Brass Pin Kenzans

  • Naturally resistant to rust and corrosion.
  • Suitable for almost all types of fresh flowers and foliage.
  • Ideal for ikebana, contemporary floral design, and everyday flower arranging.
  • Excellent for arrangements that remain in water for longer periods.
  • Long-lasting, reusable, and easy to maintain.

Which Kenzan Should You Choose?

Both steel and brass kenzans are excellent flower arranging tools, and the right choice depends on the flowers and floral designs you create most often.

Choose a Steel Pin Kenzan if you:

  • Regularly work with thick, woody, or particularly heavy stems.
  • Need maximum strength for structural floral designs.
  • Create large floral arrangements, event installations, or commercial floristry work.
  • Want a robust flower frog for demanding everyday use.

Choose a Brass Pin Kenzan if you:

  • Work with a wide variety of fresh flowers and foliage.
  • Enjoy ikebana or natural-style flower arranging.
  • Want superior resistance to rust and corrosion.
  • Need a versatile, long-lasting flower frog for everyday floral design.

Are Both Kenzans Suitable for Fresh Flowers?

Yes. Both steel pin kenzans and brass pin kenzans are designed for use with fresh flowers and foliage. They securely anchor stems while allowing maximum water access, helping flowers stay hydrated and beautifully displayed.

The primary difference is that steel offers exceptional strength for heavier botanical materials, while brass provides excellent corrosion resistance and outstanding versatility for almost all fresh flower arrangements.

Why Choose a Kenzan Instead of Floral Foam?

Kenzans are a reusable and environmentally friendly alternative to single-use floral foam. Rather than inserting stems into foam, flowers are supported mechanically by the pins, allowing them to absorb water naturally while creating open, elegant floral designs.

Benefits of using a kenzan include:

  • Reusable for years with proper care.
  • Reduces reliance on single-use floral foam.
  • Encourages better water circulation around flower stems.
  • Creates natural, airy floral arrangements.
  • Suitable for ikebana, modern floristry, event styling, and home flower arranging.
