Pelargonium cucullatum is a fast-growing, fairly tall, sprawling shrub, up to 6.6 feet (2 m) tall. The leaves are up to 3.1 inches (8 cm) wide, grow upwards, forming circular bowls with jagged, red-tipped edges. The flowers are faintly scented, purple or pink and appear for several months over the summer.
How to Grow and Care
Work organic compost into high-quality container potting soil that contains ingredients such as peat moss, vermiculite and perlite. Use this compost/soil mixture to fill pots for your Pelargoniums. Good drainage is essential to Pelargoniums so choose containers with adequate drainage holes. If your Pelargoniums are already in pots, spread organic compost lightly on the soil surface and work in, taking care not to dig up the plant’s roots.
Choose locations getting direct sun for most Pelargoniums. They need at least six hours of sun daily. Martha Washington and Regal types prefer a site that is shady in the afternoon. All Pelargoniums need afternoon shade if your area regularly sees summer temperatures exceeding 90 degrees Fahrenheit (32 degrees Celsius).
Feed your Pelargoniums every two weeks with a balanced fertilizer like 10-10-10 or 20-20-20. Buy fertilizer that dissolves in water for easier application. Every third watering, add Epsom salts — magnesium sulfate — to the plant water — 1 teaspoon per 1 gallon — to provide magnesium. Or, add a slow-release fertilizer to the soil mix when you plant the geraniums in the pot — it feeds them all season…
