Description

A vigorous pelargonium with an upright or semi-trailing habit, depending on the variety, and a rounded crown. From spring until mid-autumn, it produces umbel-shaped inflorescences with petals in a wide range of colours, creating colourful and eye-catching displays in pots and planters, making it the ideal choice for enhancing terraces, balconies and building façades. It is highly hardy and requires little maintenance.

Curiosities and special features

The term Pelargonium derives from the Greek ‘pelargos’, meaning ‘stork’, in reference to the shape of its seeds, which resemble a stork’s beak, whilst the specific epithet ‘zonal’ refers to the dark zones or bands that characterise the leaves.

Origin and distribution

A species native to the region stretching from the Cape Province to the coastal province of KwaZulu-Natal in South Africa, it was introduced to Europe in the 17th century.

Initially classified by C. Linnaeus as belonging to the genus Geranium, it was later assigned to the genus Pelargonium, which was officially established in the late 18th century by the botanist L’Hèritier.

Commonly known as the zonal pelargonium, it features a wide range of varieties prized by both professional growers and hobbyists for their brightly coloured blooms and ease of cultivation.

Plant height

The plant grows to a height of m, making it ideal for mixed plantings with other ornamental plants.

Flower

The flower is semi-double, medium-sized, with a dialipetal corolla and solid-coloured petals. It is arranged in medium-sized umbel-like inflorescences. It flowers from early spring to mid-autumn, with a flowering period of between 190 and 210 days.

PH

It grows well in substrates or soils with a slightly acidic pH, particularly with values between 5.8 and 6.5.

Values below 5.3 can lead to excesses of manganese and iron, which first become apparent on the lower leaves as chlorosis and punctate necrosis along the leaf margins.

Ideal climate and temperature

The ideal temperature ranges from {F1} to {F2} °C; it grows and flowers well in warm temperate climates.The optimal temperature ranges from {F1} to {F2} °C.

Soil

For use in pots and planters, we recommend a good-quality potting mix specifically designed for spring-flowering plants, which is well-draining and contains peat and perlite.

Combinations with other plants

Recommended for planting alongside other ornamental plants such as Angelonia angustifolia, Brachyscome multifida,Euphorbia hypericifolia, Glechoma hederacea, Helichrysum petiolare, Heliotropium arborescens, Lobelia erinus, Lobularia xhybrida, Sanvitalia speciosa, Sutera diffusa, Plectranthus coleoides, Verbena x hybrida and Vinca.

care should be taken when arranging the plants in advance according to a design plan that takes into account their mature height as well as colour combinations in relation to the chosen varieties.

Propagation

Vegetative propagation is carried out by taking cuttings.

Watering

Use rainwater, or tap water if necessary, by watering by hand, using a drip system or through sub-irrigation.

In the initial stages following repotting, look after the seedling to prevent stress in its new location. Thereafter, allow the growing medium to dry out slightly between waterings, preventing both periods of drought and waterlogging, the latter of which can cause fungal diseases and root rot, leading to the death of the entire plant.

It is advisable not to wet the above-ground parts in the late afternoon or evening to prevent the development of plant diseases.

Fertilising

This plant requires a fair amount of fertiliser, but care must be taken to avoid over-fertilisation, particularly at the start of cultivation, as this can lower the pH of the growing medium.

During the spring and summer months, add a liquid fertiliser to the growing medium – to be diluted in the watering water – specifically formulated for ornamental plants and containing the nutrients the plant requires. This will promote growth and the production of new flowers, ensuring a balanced development between foliage and inflorescences.

Fertilisation should be regular but not excessive. Insufficient fertilisation first causes the foliage to lighten in colour and then leads to the older leaves turning red.
