Frequently Asked Questions: Flower Frog Kenzan Stayputs

A kenzan, also known as a flower frog, stayput or pinwheel, is a heavy metal base fitted with sharp upright pins. It sits inside a shallow container and holds flower stems, foliage and branches securely in position without the need for floral foam. Kenzans are an essential tool in ikebana, the Japanese art of flower arranging.

What is the difference between steel and brass kenzans?
The Steel Pin Kenzan Range offers a more affordable alternative to the existing Brass Pin Range while providing the same familiar size options. Steel kenzans are ideal for students, hobbyists and florists looking for an accessible option or wanting to stock multiple sizes. Brass kenzans are the premium option, offering harder pins, greater rust resistance and longer pin life.

Which size kenzan should I choose?
Choose a size that fits comfortably inside your vessel and allows the kenzan to sit approximately 1.5–2cm below the vessel rim. Mini 34mm and Small 40mm kenzans suit smaller containers, Medium 50mm suits medium shallow bowls, while the XLarge 70mm and Rectangular 58x83mm options are suited to larger shallow dishes. Rectangular kenzans work particularly well in rectangular or oval vessels.

What types of flowers and stems can I use with a kenzan?
Kenzans can hold a variety of floral materials, including soft stems, grasses, woody branches and mixed arrangements. They can also be used with fresh, dried and preserved flowers, foliage and branches.

What type of vessel should I use with a kenzan?
Kenzans are designed for shallow vessels such as suiban used in moribana-style ikebana. Shallow ceramic bowls, dishes and low vases are suitable options.

Do I need to secure my kenzan to the vessel?
In most shallow vessels, the weight of the kenzan helps keep it securely in place. For additional stability, particularly when using a smaller kenzan in a wide container or arranging heavier branches, florist clay such as SureStick can be applied to the base.

Can steel kenzans rust?
Yes. Alloy steel can rust over time if it is left wet or isn't dried properly after use. To help minimise rust, rinse your kenzan after each use, clean away organic residue and dry it thoroughly before storing. Do not leave your steel kenzan submerged in water when it isn't being used.

How do I clean and care for my kenzan?
After use, remove the stems and rinse the kenzan under running water. Gently scrub between and around the pins with a dedicated kenzan brush to remove organic matter and resin residue. Rinse again and dry thoroughly before storing. Regular cleaning helps prevent rust and maintain the grip and performance of the pins. 

Can bent kenzan pins be repaired?
Yes. If pins become bent or misaligned, a kenzan pin straightener can be used to carefully return them to position. This is particularly useful after working with thicker, woody stems and can help extend the useful life of your kenzan.

Are kenzans reusable?
Yes. Unlike single-use floral foam, kenzans are designed to be cleaned and reused. With regular cleaning, thorough drying and occasional pin straightening, they can be used repeatedly for floral arrangements.

Are kenzans an alternative to floral foam?
Yes. Kenzans provide a reusable, foam-free way to secure flowers and foliage in arrangements. They allow stems to sit directly in water while creating the open, minimalist designs associated with ikebana and contemporary floral styling.

Can I use a kenzan with dried flowers?
Yes. Kenzans can be used with both fresh and dried materials, including preserved florals, branches and foliage, making them suitable for traditional ikebana as well as contemporary floral arrangements.

Are kenzans safe to handle?
Kenzans contain sharp upright pins and should always be handled with care. They are not suitable for children and should be kept out of reach when not in use.
