Pelargonium aka Geranium

Taxonomy

Pelargonium and Geranium are two related genera of flowering plants in the family Geraniaceae. Pelargonium includes approximately 280 species of perennials, succulents, and shrubs, commonly known as geraniums, pelargoniums, or storksbills. On the other hand, Geranium is a separate genus with 422 species of annual, biennial, and perennial plants, also known as geraniums or cranesbills. While Geranium species are mainly herbaceous plants that die down in winter, Pelargonium species are evergreen perennials found in warm temperate and tropical regions, particularly in southern Africa. They are known for their drought and heat tolerance, although they can only withstand minor frosts. Many Pelargonium species are popular garden plants, grown as houseplants or bedding plants in temperate regions. They have a long flowering period, with flowers typically in shades of red, orange, or white. The cultivars of Pelargonium have been extensively bred, resulting in a wide variety of sizes, flower colors, leaf forms, and aromatic foliage. One specific Pelargonium variety is 'Stellar Deanna Westwood', which is an evergreen perennial with bushy growth reaching about 40cm in height. It features lime-green foliage with a central red zone and pointed lobes. This variety produces clusters of vivid pink flowers from spring to autumn. Geraniums, or cranesbills, are found in temperate regions worldwide and the mountainous areas of the tropics, particularly in the eastern part of the Mediterranean region. They have palmately cleft leaves that are generally circular in shape. The flowers have five petals and come in various colors such as white, pink, purple, or blue, often with distinctive veining. Geraniums can thrive in different types of soil, as long as it is not waterlogged. They can be propagated through semiripe cuttings, seeds, or division during autumn or spring.

How to care for Geranium

Difficulty

Geranium requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

Water

Geranium should be watered regularly, allowing the soil to dry out between waterings.

Soil

Geranium loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Geranium prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Toxicity

Ploi does not possess verified information regarding the toxicity of this particular plant. In the event that you, a member of your family, or a pet ingests plant material with an unclear toxicity level, it is highly recommended to seek the advice of a medical professional.

Humidity

The Geranium does not necessitate supplementary humidity. Plants primarily absorb water through their roots, rather than their leaves. Hence, the most effective way to supply humidity to your plants is by watering the soil.

Fertilizer

The Geranium should be transferred to a new pot once it has increased in size two-fold, or on an annual basis, whichever occurs earlier. Replacing the soil with fresh potting soil containing all the necessary nutrients, is sufficient enough to support the growth of the plant, thus avoiding the need to use fertilizer. It's important to note that plants derive their energy from the sun and not fertilizer.

Region of origin

Geranium’s native range is Tropical and Subtropical regions worldwide.
