Title: Fragrance in fragrant plants.
Answered by: Jimmy Mills

QUESTION:

Why are some flowering plants known for fragrance not fragrant or as fragrant? Is it a nutrition deficiency or just the plant?

ANSWER:

It isn’t clear to Mr. Smarty Plants what you are asking. The word fragrance  is a noun, and the word fragrant   is an adjective.

 Fragrance in plants is most often associated with flowers, and it is presumed by some people that the purpose of the fragrance is to attract pollinators. Other parts of some plants are fragrant such as the leaves of herbs eg parsely, sage, rosemary, and thyme as well as members of the mint family. The fragrance is due to the production of volatile oils and is characteristic to the particular species.

The production of the volatile oils is part  of the plant’s natural metabolism, and maybe a nutrient deficiency could affect the amount of oil production, and thus the fragrance, similar to the way a deficiency in nitrogen affects the production of chlorophyll, which results in yellow leaves.

Perhaps you could reformulate your question, and give us another chance.
