Pelargonium graveolens, commonly called the rose-scented geranium, is an evergreen, shrubby pelargonium native to southern Africa. Growing 60–120 cm tall, it bears soft, velvety, deeply lobed leaves packed with glandular hairs that release a distinctive rose-like fragrance when brushed. Clusters of pale pink to mauve flowers, often veined in darker tones, appear from spring through summer and attract bees and other pollinators. The aromatic foliage is distilled to produce geranium essential oil prized in perfumery, aromatherapy, and flavoring. In cultivation, it prefers bright light, lean, sharply drained soils, and modest watering, thriving in containers, herb gardens, and sunny borders. Plants respond well to pruning, which maintains a compact form and stimulates fresh, aromatic growth suitable for potpourri and culinary garnishes. Though tolerant of heat, wind, and short dry spells, it is tender to frost and typically overwintered indoors in cold climates. Its resilience, fragrance, and versatility make it a favorite for scented collections and low-maintenance, drought-aware plantings.

How to care for Rose-scented geranium
Water
Allow the top 2–3 cm (1 inch) of the mix to dry before watering. Then water deeply until excess drains, discarding runoff. In active growth and warm weather, this may be weekly; in cool or low light, extend intervals. Keep on the drier side—wet, airless soil invites root rot. Reduce watering markedly in winter dormancy, giving just enough to prevent complete desiccation. Use a fast-draining medium and a pot with generous drainage holes.
Light
Provide full sun to bright light: outdoors, 5–6+ hours of direct sun is ideal. In hot climates, give morning sun with light afternoon shade to prevent leaf scorch. Indoors, place at a sunny south or west window; supplement with grow lights 12–14 hours daily if needed. Insufficient light leads to lanky growth and fewer scented leaves; rotate the pot weekly for even shape.
Nutrients
Feed sparingly. During spring and summer, apply a balanced, low-to-moderate nitrogen fertilizer (e.g., 5-5-5 or 10-10-10) at half strength every 4–6 weeks, or use a light slow-release organic blend. Excess nitrogen encourages soft, leggy growth and dilutes fragrance. Incorporate a small amount of compost at repotting, and consider occasional kelp or micronutrient feeds. Flush the pot monthly with plain water to avoid salt buildup. Withhold fertilizer in late summer to autumn as growth slows.
Temperature
Ideal temperatures are 60–75°F (16–24°C) by day with cooler nights. It tolerates brief heat to around 85–90°F (29–32°C) if well-lit and not overwatered. Protect from frost; sustained exposure below 40°F (4°C) damages foliage, and freezing is lethal. In cold regions, overwinter indoors in bright, cool conditions with good airflow. Avoid sudden temperature swings and hot, stagnant rooms, which increase pest pressure and stress.
