Cultural Characteristics Around the World

Lemon geranium has played a significant role in European herb garden and greenhouse culture, valued for its aromatic qualities. In Britain, herb gardening flourished from the 18th century onward, and this plant was recognized for its fragrant foliage. It was cultivated in greenhouses and winter gardens, and its scent was appreciated in tea rooms and parlors.

In France’s Provence region, where garden design emphasizes aromatic plants, this species is often used in summer gardens. In countries like Germany and the Netherlands, it remains a popular choice for window boxes and among households that value aromatic plants, maintaining a steady place in European gardening traditions.

Historical Background

Lemon geranium was introduced to Europe in the late 17th century as one of many Pelargonium species from South Africa. At the time, collecting and displaying exotic plants from colonial territories became a popular trend among European aristocrats, and greenhouses and botanical gardens were filled with such rarities. Pelargonium crispum drew attention with its distinctive leaf shape and fragrance and became a leading example of “scented geraniums.”

From the 18th to 19th centuries, horticultural breeding advanced significantly, and numerous hybrid varieties were developed. Lemon geranium was used as a parent plant in many of these crossings.

During the Victorian era, it was known as a “greenhouse flower with fragrance,” and it was reportedly grown in royal greenhouses, indicating its cultural significance at the time.

Gardening Advice

Lemon geranium is easy to care for and enjoyable for both its scent and flowers. Below are practical care tips.

Sunlight

Prefers sunny locations. It tolerates direct sunlight well and can be grown outdoors from spring to autumn. Indoors, place it by a bright window.

Watering

Water thoroughly when the surface of the soil is dry. Avoid overwatering, as excessive moisture may cause root rot.

Soil

Use well-drained potting soil. Mixing commercial flower soil with perlite or small-grain akadama soil helps improve aeration.

Fertilizer

During the growing season (spring to summer), apply liquid fertilizer every 2–3 weeks. Refrain from fertilizing in winter.

Pruning

Prune overgrown branches during the growing season to maintain shape. Regular trimming encourages branching and enhances the plant’s appearance.

Overwintering

Not frost-tolerant. Move indoors during winter. In cold climates (below 5°C), avoid outdoor cultivation. Indoors, place it in a bright and moderately humid location.

Conclusion

Lemon geranium is a perennial plant admired for its refreshing scent and compact, decorative flowers. Although native to South Africa, it became widely accepted in Europe after the 17th century and was especially valued by gardeners and enthusiasts who appreciated aromatic plants.

With proper care in terms of sunlight and drainage, the beauty of its foliage and fragrance can be enjoyed in daily life. It is well-suited to potted and balcony gardening and serves as a delightful addition of color and scent to any home environment.
