What characteristic defines succulents in floral arrangements?

Succulents are defined by their thick, fleshy leaves that store water, which is a key adaptation for survival in arid environments. This characteristic allows them to thrive in conditions where water is scarce, making them highly resilient and suitable for various floral arrangements. Their ability to retain moisture also allows them to endure longer periods without water, contributing to their popularity in arrangements that are designed to last.

While vibrant colors, long-lasting blooms, and aromatic fragrances can be features of some floral elements, they do not specifically define succulents. The moisture-retaining nature of succulent leaves is a unique trait that sets them apart, making option focused on their water-storing characteristics the most accurate description of succulents in the context of floral design.
