Geraniums are beloved for their vibrant blooms and fragrant foliage, but like many garden plants, they can fall victim to pests such as aphids, whiteflies, and spider mites. This list covers geranium types known for their natural resistance to these common pests, making them ideal for gardeners seeking low-maintenance, pest-resilient plants. Whether you’re a novice or an experienced gardener, these geranium varieties can help keep your garden flourishing with less chemical intervention.
Pelargonium ‘Citronella’ (Mosquito Geranium)
Pelargonium ‘Citronella’ is renowned for its unique lemon-scented foliage, which not only deters mosquitoes but also repels aphids and whiteflies. This variety’s strong aromatic oils act as a natural insect deterrent, making it a popular choice for outdoor containers and patios. Its upright growth habit and bright pink flowers add ornamental value while keeping pests at bay.
Pelargonium ‘Mrs. Pollock’
‘Mrs. Pollock’ is a robust, scented-leaf geranium featuring dark green, deeply lobed leaves with a lemon-mint scent that discourages spider mites and aphids. This variety is highly tolerant of heat and drought, which helps reduce pest infestations that thrive in stressed plants. Its clusters of soft pink flowers provide a lovely contrast to the foliage, making it both functional and attractive.
Pelargonium ‘Attar of Roses’
Famous for its strong rose fragrance, ‘Attar of Roses’ produces thick, fuzzy leaves that are less appealing to common pests like whiteflies and aphids. The dense leaf texture acts as a physical barrier, while its aromatic oils repel many insects. This variety also boasts soft pink blooms and is prized for its use in potpourri and essential oils.
Pelargonium ‘Fringed Lavender Rose’
With its finely fringed petals and lightly scented leaves, ‘Fringed Lavender Rose’ offers moderate resistance to spider mites and aphids. The slightly hairy leaf surface reduces pest attachment and feeding, while its striking lavender-rose flowers brighten garden beds. This variety thrives in well-drained soil and full sun, conditions that discourage many pest populations.
Pelargonium ‘Lara Star’
‘Lara Star’ is a compact scented geranium known for its spicy, lemony aroma that helps deter aphids and whiteflies. Its glossy, dark green leaves and vibrant coral-pink flowers make it a popular choice for both indoor and outdoor settings. This cultivar’s resilience to pests is enhanced by its vigorous growth and good air circulation when properly spaced.
Pelargonium ‘Black Velvet’
Primarily grown for its striking almost-black velvety foliage, ‘Black Velvet’ also exhibits natural resistance to common pests due to its thick, textured leaves. The dark leaves tend to be less attractive to aphids and spider mites, which often prefer smoother surfaces. Though its pale pink flowers are less showy, the unique foliage makes it a standout in any garden.
Pelargonium tomentosum (Peppermint-scented Geranium)
Native to South Africa, Pelargonium tomentosum has fuzzy, peppermint-scented leaves that repel a variety of pests including aphids and whiteflies. Its strong mint fragrance and dense leaf hairs create an inhospitable environment for insects. It produces small white flowers and is often used as a culinary herb or in natural insect repellents.
Pelargonium ‘Mrs. Taylor’
‘Mrs. Taylor’ is a rose-scented geranium with finely textured leaves that provide moderate resistance to spider mites and aphids. This variety is favored for its compact growth and prolific pink blooms, which add color without attracting many pests. Its tolerance to heat and drought helps reduce pest pressure caused by plant stress.
Pelargonium ‘Mrs. Parker’
Known for its lemon-scented foliage, ‘Mrs. Parker’ deters aphids and whiteflies effectively. The plant’s coarse-textured leaves and strong aroma discourage many common garden pests, reducing the need for pesticides. It produces soft pink flowers and performs well in containers or garden beds with full sun exposure.
Pelargonium ‘Lemon Fizz’
‘Lemon Fizz’ offers a bright lemon scent that helps keep aphids, spider mites, and whiteflies at bay. Its compact growth habit and variegated green-and-yellow leaves add visual interest alongside pest resistance. This cultivar thrives in well-drained soil and sunny conditions, where its natural defenses are most effective.
How to Choose
When selecting a pest-resistant geranium, focus on leaf texture, scent, and growth habit. Aromatic oils in scented-leaf geraniums are key to deterring pests like aphids and whiteflies, so varieties with strong lemon, mint, or rose fragrances tend to perform best. Leaf fuzziness or hairiness can also create physical barriers to insects, reducing infestations. Choose cultivars suited to your climate and garden conditions, as healthy plants are less vulnerable to pests. Additionally, consider flower color and plant size to match your aesthetic preferences while maintaining pest resistance.
