Noteworthy CharacteristicsLeaves that release scent when touched. Especially good in containers.

CareIn a container, ensure drainage and adequate moisture by using a good potting mix that contains ingredients such as peat moss, pasteurized compost, and perlite. Use a timed-released fertilizer in the soil or an all-purpose liquid fertilizer when you water. Pelargoniums like magnesium, and a teaspoon of epsom salts (magnesium sulfate) added to each gallon of fertilizer solution every few waterings will adequately supply this nutrient. As with plants in the ground, place containers in the full sun. When temperatures get above 90°F, pelargoniums appreciate some afternoon shade. Bring potted plants indoors before outdoor temperatures drop below 45°F to avoid shocking them. Place them in a south-facing windowsill that gets at least four hours of direct sunlight a day. They will not tolerate poor drainage.

PropagationSow seed at 70°F in late winter or early spring, or take softwood cuttings in spring, late summer, or early fall.
