Zonal pelargonium, commonly known as geranium, is a popular choice for home gardeners due to its beautiful blooms and ease of care. However, it is important to note that zonal pelargonium possesses a unique attribute: it repels bees. This characteristic is known among gardeners, entomologists, and homeowners alike. Zonal pelargonium contains geraniol, a natural compound that emits a scent that bees find unpleasant. As a result, bees tend to avoid areas where zonal pelargonium is present, making it an effective natural bee repellent.

Chemical Composition of Pelargoniums: Unraveling Nature’s Wonder
Pelargoniums, revered for their exquisite blooms and aromatic foliage, possess a wealth of natural compounds that contribute to their remarkable properties. Among these is a trio of essential oils: citronellol, geraniol, and eugenol.
Citronellol, a monoterpene alcohol, imparts a refreshing citrusy scent to pelargoniums. It possesses insect-repellent and antibacterial properties, making it a valuable natural remedy for deterring pests and purifying the air.
Geraniol, another monoterpene alcohol, exudes a sweet, rosy fragrance. It exhibits antioxidant and anti-inflammatory properties, contributing to the plant’s health and resilience. Geraniol also plays a role in attracting beneficial insects, creating a harmonious ecosystem in the garden.
Eugenol, a phenylpropene, boasts a spicy, clove-like aroma. Its antiseptic and analgesic properties have been traditionally used to alleviate pain and promote healing. Eugenol also contributes to the insect-repellent nature of pelargoniums.
The synergistic interplay of these compounds bestows upon pelargoniums a wide range of beneficial properties, including air purification, insect control, and soothing skincare. By harnessing the power of nature, we can cultivate these remarkable plants and enjoy their myriad benefits.

Insect Repellency
Pelargoniums, particularly the Lady Washington and Pelargonium hortorum varieties, possess a unique chemical composition that acts as a natural insect repellent. Their leaves release volatile compounds, such as citronellol, geraniol, and eugenol, which effectively deter pests like mosquitoes, flies, and aphids.

Pest Control
Not only do pelargoniums repel insects, but they also have pesticidal properties. Companion planting with pelargoniums can help reduce pest populations in your garden. For instance, planting them near roses or tomatoes can help control aphids and whiteflies. Their root exudates have been shown to suppress certain soil-borne pathogens, providing additional protection for your plants.
Air Purification
In addition to their pest-control abilities, pelargoniums contribute to a healthier indoor environment by purifying the air. They absorb and remove harmful toxins, such as formaldehyde and benzene, from the atmosphere.
