Key information

Description

Compact-growing tuberous herbaceous plant with an erect habit bearing herbaceous flower stems in the centre. It is a very showy plant due to its large, globular flowers with a wide range of colours. Appreciated as an ornamental plant precisely because of its inflorescences which show themselves, depending on the variety, in seasons when there are often not many other blooms, thus allowing for scalar programming throughout the year. With its wide versatility, it is suitable both in flowerbeds and for balconies and terraces in pots or planters, even in compositions with other species. It requires no special cultivation care as long as certain requirements are met beforehand, such as a half-shade exposure and adequate irrigation free of water stagnation.

Variety description

It is a very showy plant with very large and colourful flowers, suitable for use in bowls or tubs on balconies.

Origin and history

Curiosities and special features

Tradition has it that buttercups are brought to altars dedicated to the Virgin Mary during Holy Week because, according to an ancient legend, Jesus chose the brightest stars from the sky and turned them into buttercups to pay homage to his Mother. Its name derives from the Greek batràchion, later Latinised, meaning little frog, as the earliest records associated its growth in swampy, damp areas. The flowers of some varieties are also suitable as cut flowers for bouquets and fresh arrangements.

Origin and distribution

Native to Asia Minor and Western Europe, the buttercup seems to have arrived in Europe during the Crusader period thanks to Louis IX, King of France, after his return from Palestine. At first it did not arouse much interest except to be cultivated in monastery gardens together with ornamental bulbous plants.

It reached its peak in the late 17th century, during the reign of Muhammad IV of Turkey, becoming the most sought-after decorative plant for the gardens of Constantinople. It was later reintroduced, via Greece, into Europe, leading to intensive hybridisation in England, France and Holland in the 19th century. Today it is cultivated in several Mediterranean countries, in Holland and in South Africa;Italyis among the main buttercup-producing countries.

Main features

Flower size

The flower individually is average in size compared to other varieties of the same species.

Leaf

Leaf has a palmately lobed lamina.

Flowering period

Flowering lasts from mid-winter to late spring for a duration of 40 to 60 days, allowing us to admire the colour tones of its inflorescences for a long time.

Inflorescence

Inflorescence compound spike.

Leaf colour

Mosaic tone.

Plant height

The height of the plant varies from 0.15 to 0.25 m, perfect for creating sinuous movements in compositions with other ornamentals of different development.

Lifespan

Biennial plant.

Where to plant

Ideal for adding a touch of colour and elegance to balconies, outdoor tubs, flowerbeds

Stem

The stem is herbaceous and the variety has no thorns.

Flower

The flower is peoniform in shape, medium-sized, with a diapetalous corolla and plain petals. It is arranged in medium-sized compound spike inflorescences. It flowers from mid-winter to late spring, with a flowering period of between 40 and 60 days. It has sweet notes and is lightly scented, with a delicate aroma. It is attractive to beetles and bumblebees.

Growth

Compact-growing variety, excellent for creating dense monochromatic clusters with significant ornamental visual impact.

Plant habit

The habit is erect with the flower stems in the centre, giving a highly decorative overall result.

Branching

Medium branching, a characteristic that allows it to achieve a good, compact and proportionate vegetative development.

Growing conditions

PH

The optimal pH values of the Soil/medium are between 5.5 and 6.5. As most ornamental Species like slightly acidic Soil/medium, in this regard also pay attention to the pH of the irrigation water.

Soil preparation

For transplanting into beds, check that the soil is not too compact, i.e. that it hinders the proper development of the young roots; if necessary, bury sand to make it lighter and, if necessary, peat to also favour ideal pH conditions; it is also advisable, after light digging and hoeing, to add professional substrate on the surface for about 5/10 cm, preparing the planting furrows according to a suitable final density.

Sun exposure

It prefers positions in half-shade; direct sunlight should be avoided, particularly during the peak flowering phase.

Ideal climate and temperature

Theideal temperature is between 10 and 20 °C; these temperature values enable excellent growth and flowering results. In areas with harsh winters, protection with mulch is recommended.

Use

Always admired and appreciated for its showy and elegant flowers, it is widely used as a plant in
Ornamental

Hardiness

Not a hardy variety, it fears waterlogging and does not tolerate strong sunlight.

Soil

The ideal soil for buttercups is peaty and well-draining; for use in planters and pots, a light peat and perlite-based substrate with a sub-acidic pH is recommended.

Difficulty

Cultivation is easy; with proper care, excellent growth and flowering results can be achieved.

Growing tips

For best vegetative development followed by lush flowering, it is recommended to

Avoid direct sunlight during the hottest hours Prefers cool climate

Combinations with other plants

It is the ideal solution not only for creating compact, monochrome light clusters but also for compositions, according to harmonious and proportionate patterns, with other ornamental species such as Anemone coronaria, Antirrhinum majus, Calendula officinalis, Iberis sempervirens, Viola. The combinations may involve shades of the same colour tone or combinations of different colours according to carefully composed, uniform and restful patterns, defined on the basis of a series of factors such as personal taste, season and duration of flowering as well as the final height reached by each individual species.

Care and plant health

Planting

As with any ornamental bedding species, planting should be done at a suitable density in order to ensure the expression of the best vigour in growth, thus obtaining proportionate and visually harmonious final effects; we therefore recommend an average planting density of 15 plants per square metre. We also suggest placing each seedling on a raised bed with the collar outside the soil surface, taking care not to damage the roots and avoiding completely sinking the root balls, which must be well moistened; finally, water immediately after planting, preferably during the morning hours.

Propagation

Mainly reproduction is from seed.

Watering

Use rainwater, alternatively well or aqueduct water with a sub-acidic optimum pH, either manually or with an irrigation system. When transplanting, prevent waterlogging and water constantly without causing dryness; do not allow the plant to dehydrate after repotting.

Afterwards irrigate with adequate quantities not directly on the flowers, keeping the soil or substrate moist but avoiding both waterlogging, which causes root rot, and deficiencies which can lead to yellowing of the leaves.

Fertilising

From the end of winter until the end of spring, following proper settlement in the new planting site, apply a liquid fertiliser suitable for ornamental species to the soil or substrate at the foot of the plant without wetting the leaves, to be distributed liquid, i.e. diluted in the irrigation water, without exceeding the frequency and doses applied.

Edibility and toxicity

Pet safety

May cause toxicity by ingestion.

Edibility for humans

Non-edible.

Toxicity for humans

Buttercups contain anemonin, a substance that is particularly toxic to animals and humans if taken in specific quantities; avoid ingestion.

Expert advice

Tip

Avoid drying out the soil completely, to avoid yellowing of the basal Leaf. Avoid watering the Flower. The plant suffers greatly from waterlogging and mediums that have a lot of water retention. It does not like strong sunlight or direct sunlight.
