What Makes Scents in the Garden?

Monday, April 12, 2021

All creatures, including humans, plants, animals, and insects communicate with odor. Smell makes up one of the four methods of communication, including sound, sight, and touch.

Why are scents important for plants?

Some flowers use scent to attract pollinators. There are no identical scents in flowers, thanks to compounds and interactions. Plants that attract bees or flies will have sweet fragrances, whereas those that attract beetles will have more of a spicy and musty scent.

Why are scents important to humans? When we smell a fragrance, our limbic system is activated, and this ignites our olfactory glands, which can evoke an emotion, and even draw us into a memory.
