Which type of foliage is versatile and commonly used as a filler in flower arrangements?

Leather leaf fern is highly regarded in floral design for its versatility and abundant availability. This type of foliage features a lush, textured appearance that easily complements a variety of floral arrangements, providing a lush backdrop without overwhelming the primary flowers. Its fronds can be used to create fullness, framing the arrangement beautifully, while also serving as a useful filler that enhances the visual appeal of compositions.

Leather leaf fern also holds its shape and color well, making it a dependable choice for both fresh and dried arrangements. Its durability allows it to maintain its aesthetic quality over time, ensuring that the overall design remains visually striking for the duration of its display.

In contrast, the other types of foliage listed may have their own unique uses, but they do not offer the same level of versatility and widespread application as the leather leaf fern. Ti leaves, while vibrant, are often used more for their bold color rather than as generalized filler. Tree fern offers a different texture but is less common in everyday arrangements. Lycopodium has a more delicate appearance and is typically used for specific seasonal items rather than as a standard filler in general floral work.
