Description

Ornamental herb with vigorous growth and an upright or semi-erect habit depending on the variety. Flowering is lush and prolonged and occurs during the spring-summer period with a profusion of brightly coloured, shiny flowers. Easy to maintain, it is used to decorate flower beds, outdoor tubs, planters and pots, also in compositions with other ornamental or with varieties of the same species with different coloured flowers. It is often distinguished from the genus Petunia by the smaller size of the flowers associated with a more abundant flowering, it also has a high level of tillering with a flower/leaf ratio of great decorative effect.

Variety description

Extremely attractive plant for balcony trays. Very re-blooming throughout the summer and early autumn. The series includes a wide assortment of colours, and small to medium-sized flowers that recover quickly even after a heavy downpour. The selection is definitely more compact than the other series. It is also suitable for the production of small 12-diameter pots.

Curiosities and special features

The generic epithet, Calibrachoa, comes from the Mexican botanist and pharmacologist Antonio de Cal y Bracho.

Origin and distribution

The genus Calibrachoa, whose separation from the genus Petunia took place in 1825 but was later confirmed in 1985 on a chromosomal basis, is native to South and Central America. There are currently 28 hybridised species selected for phenotypic characteristics such as the widely varying flower colour as well as the plant's developed habit.

Flower size

The flower individually is small, but the flowering as a whole is abundant, showing us a cascade of vibrantly coloured inflorescences.

Leaf

Leaf has obovate lamina.

Flowering period

Flowering lasts from mid-spring to early autumn for between 120 and 160 days, allowing you to decorate your green spaces even during the hottest period.

Inflorescence

Inflorescence corymb.

Leaf colour

Solid colour tone.

Plant height

The height of the plant varies from 0.15 to 0.25 m. It can easily be combined with other flowering plants in the garden with an alternation of colours and heights, resulting in a pleasant overall movement.

Lifespan

Plant grown as a seasonal.

Where to plant

Due to its vigorous growth and spectacular flowering, it is mainly used in outdoor spaces such as flower beds, balconies, hanging baskets, planters, outdoor tubs

Stem

Herbaceous stem, the variety has no thorns.

Flower

The flower has a simple, small form with a gamopetalous corolla and plain petals. It is arranged in medium to small corymbal inflorescences. It flowers from mid-spring to early autumn, with a flowering period of between 120 and 160 days. It is not particularly attractive to pollinating insects.

Growth

The growth is medium to vigorous, thus representing among the seasonal ornamental species a perfect choice to decorate your green spaces throughout the spring-summer period.

Plant habit

The habit is globular, making it ideal for use in planters and balconies.

Branching

It develops abundant branching, giving it a well-tended, rich Leaf and Flower appearance.

PH

The optimum pH of the Soil/medium is slightly acidic, between 5.00 and 6.00; values above 7.00 can lead to yellowing of the vegetative apices.

Soil preparation

Before transplanting into the bed in spring, it is necessary to prepare the soil properly; to this end, dig up the soil and remove any weeds and bulky stones, then bury slow-release organic or chemical fertiliser and, if the soil is compact and not very draining, add sand. Continue by breaking up the coarsest clods to give greater softness and carefully levelling by preparing the planting holes according to a suitable density.

Sun exposure

Suitable for positions in half shade, full sun; in order to obtain copious flowering, prefer sunny exposures if possible.

Ideal climate and temperature

It offers the best development and growth results in areas with a warm temperate spring-summer climate. The ideal temperature is between 16 and 20 °C. The biological temperature is between 12 and 30 °C.

Use

Creating pleasing and elegant overall effects with its blooms, it is widely used as a plant in
Indoor ornamental

Hardiness

Variety of medium hardiness, tolerates heat and temporary drought.

Soil

It prefers peaty soil with good drainage and adequate porosity; for pots and planters use a substrate for spring plants based on peat and perlite.

Difficulty

A fairly easy plant to cultivate and maintain, always considering its needs in terms of balanced water and fertiliser inputs aimed at achieving good vegetative growth and thriving flowering.

Growing tips

In order to achieve proper development and lush flowering, pay attention to the following cultivation requirements:

Avoid over-watering

Combinations with other plants

It is possible to create compositions with elegant and lively colour tones with other ornamental species of different flower and leaf shades such as Angelonia angustifolia, Bidens ferulifolium, Lobelia speciosa, Petunia x hybrida, Plectranthus coleoides or by combining varieties of calibrachoa with flowers of different shades to achieve harmonious colour balances.

Planting

When transplanting, apply an average density of 6 plants per square metre to allow for adequate development of each specimen. It is also suggested to place each plant with the collar above the soil surface without sinking the lump completely and watering immediately after planting, preferably during the morning hours.

Propagation

Mainly by apical cutting.

Watering

It requires abundant watering, but without stagnation, modulated in relation to the climatic conditions so as to keep the soil or substrate at a constant humidity, avoiding both excess watering, which causes root rot, and dryness, which can lead to leaf yellowing.

Fertilising

During pre-transplant soil preparation, carry out background fertilisation by burying slow-release organic or chemical fertiliser. Subsequently, during the spring-summer period, regularly apply a specific fertiliser for ornamentals to the Soil/medium at the foot of the plant, to be distributed liquid, i.e. diluted in the irrigation water, without exceeding the frequency and doses applied.

Pet safety

Toxicity to pets not known; consider case-specific and do not administer.

Edibility for humans

Inedible.

Toxicity for humans

Toxicity not known, avoid ingestion.

Tip

It is important to re-fertilize the plants regularly throughout the summer in order to have an excellent, abundant and long-lasting flowering as well as good plant growth. Do not create water stagnation to prevent the root system from rotting.
