Which aid helps provide a point for inserting flowers into the base medium?

The correct answer, floral picks, serve a crucial purpose in floral arrangements by providing a sturdy point for inserting flowers into the base medium, such as floral foam or other structural materials. Floral picks are often wood or plastic sticks that can be inserted into foam or soil, allowing for better placement and stability of the flowers. They help to hold the flowers in place and assist florists in achieving the desired height and positioning.

In contrast, machine picks are typically used in industrial contexts for sorting and handling products rather than in floral arrangements. Wires are indeed versatile tools used in floristry for securing stems or creating structures, but they do not provide a stable insertion point for flowers—weaving flowers into wires can often be more complex and less supportive. Crown picks, while useful for specific applications, such as holding and enhancing certain types of floral arrangements like bouquets, are not as universally applicable for inserting flowers into a medium as floral picks are.
