Many factors can contribute to a lack of fragrance in flowers. It's not always a problem; sometimes it's simply the nature of the plant. However, several common causes can be addressed.
Reasons for Lack of Fragrance
-
Modern Plant Breeding: Unfortunately, modern plant breeding often prioritizes visual characteristics like vibrant color and long-lasting blooms over fragrance. This has led to many popular flower varieties having significantly less scent than their ancestors. [Reference: Unfortunately for gardeners, modern plant breeding has caused many of the most popular flowers to lose much of the scent of their ancestors.]
-
Environmental Factors: The intensity of a flower's fragrance can depend heavily on environmental conditions. These include:
- Temperature: Some flowers are more fragrant in specific temperature ranges.
- Humidity: Similar to temperature, humidity levels can influence scent production. [Reference: Plant scent varies by heat and humidity- some are stronger in the evening while some in the morning.]
- Sunlight: Adequate sunlight is often necessary for optimal scent production.
-
Plant Health: A stressed or unhealthy plant may not produce its full fragrance potential. Factors like improper watering, nutrient deficiencies, or pest infestations can impact scent.
-
Time of Day: The time of day significantly affects fragrance intensity for some plants. Certain flowers release their scent more strongly in the morning or evening. [Reference: Plant scent varies by heat and humidity- some are stronger in the evening while some in the morning.]
-
Flower Age: The intensity of a flower's scent often changes throughout its lifespan. The fragrance may be strongest when the flower is newly opened and decrease as it ages.

-
Variety: Not all varieties of a given flower species are equally fragrant. Some are bred specifically for their appearance and might have little or no scent. [Reference: One of my phals listed as fragrant had no scent for the first blooms at all, and it was in bloom for 4 months. The second time it bloomed nine...]
