Students from Liceo Petrocchi visit a kindergarten and then among vines, olive trees and cypresses to see the ‘backstage’

The White Mulberry, which finds new life even in the city, in the sterile varieties. Lagerstroemia indicates suitable for resisting climate change. And then the CO2 absorbers: Quercus robur (Farnia) and Ginkgo Biloba; Acer Campestre, which consolidates the landslides and Cupressus sempervirens’ Agrimed N.1, a cancer-resistant clone of cypresses that gives and will give new life to one of the symbols of the Tuscan landscape.

Here is the hit parade of the trees of the future designed by Coldiretti Pistoia on the occasion of yesterday’s visit by students from Petrocchi art school on two farms to see ‘The art of planting landscapes’ on the Pistoia hills, in a nursery and then between vines and olive trees and cypresses .

“We wanted to put together in an ideal catalog – explains Michela Nieri, head of the Coldiretti Donne company in Pistoia – trees that are already in high demand by the market, which thanks to some special properties will design future landscapes, cities and rural areas because they is suitable for meeting environmental needs, climatic and economic. All plants grown in the oxygen factory, which is the Pistoia production center, the most important in Europe for ornamental horticulture “.

The Art of Planting Landscapes is a project created by the collaboration between Coldiretti Pistoia and the Petrocchi Art School of Pistoia, as part of the national collaboration between the Ministry of Education (Miur) and the Coldiretti Donne company, which covers part of the civic education program, on sustainable development and food education.

As part of the project, the students went to the Pistoia hills in Sant’Alessio and visited one of the most beautiful oxygen factories in Pistoia, one of the Giorgio Tesi group’s nurseries, where the students, guided by the agronomists from the company, saw the ornamental plants, who shapes and will model the urban and landscape landscapes of the future and then in the Campagna amica company “Il podere del tordo”, where the farmer Giuseppe Bartolomei (as he will be called), explained the conformation and development of the hilly Pistoia landscape with its crops: olive groves, cypresses, vineyards and acacia pressing.

“An educational visit – comments Beatrice Margiacchi, professor of literature at Petrocchi high school and coordinator of the project school -. We wanted to show the students at the artistic high school, explained directly by the main characters, the remarkable work and thoughts behind the beauty of the Tuscan countryside, modeled by farmers through the centuries. And also the research that is to refine the varieties of plants that will draw the landscapes of the future, which inevitably, in addition to beauty, must have an environmental and agronomic utility. These experiences will give the young people a greater awareness of the origin of the ‘great beauty’ in our landscapes and of the role that man, and especially the farmers, have and had in this “.

“We have selected and introduced the young high school students to the trees that best suit the needs of the future – explained Carlo Vezzosi, of the Giorgio Tesi Group Foundation – which will certainly require plants that adapt to different environments, especially urban ones. In Pistoia’s nurseries, which are oxygen factories, while they make plants grow, research and experiments are carried out on an ongoing basis, to offer the best green to cities and rural environments ”.

“Today I was so lucky to host the students of the artistic high school – said Giuseppe Bartolomei from Podere del tordo – to whom I was able to explain how we farmers have used the land, changed it, to get better productions and at the same time time to maintain the territory “. Bartolomei explained the ancient art of planting trees and their usefulness: the flat land was used to produce mainly wheat and other grains, therefore olive trees and vines were planted in difficult areas where the primary production of wheat was not possible. And the cypresses of Sant’Alessio were planted to commemorate the fallen from the First World War. Hence the Tuscan countryside with olive trees found in steep areas.

“We hope that these young artists will be able to design the future, which consists of the values ​​that Coldiretti shares: respect and preservation of the environment, the well-being of society as a whole – commented Francesco Ciarrocchi, director of Coldiretti Pistoia – the ‘Art’ project. planting ‘landscapes’ that show the ‘backstage’ can provide students with tools to create and give us an artistic synthesis that helps us better interpret our time, considering a irreplaceable role as farmers.We remember that without the work of farmers , with the abandonment of marginal areas, we are witnessing the invasion of flora and fauna, weeds: from acacia, which is not useful support of the soil due to the shallow roots, and to the excess of wild animals, which cause damage on the ground and destroys crops “.

Hit parade. Trees of the future in 5 categories

1. CORBONDIOXIDE ABSORPTION
Quercus robur (English oak)
It reaches a height of 25 to 40 m. It can be deduced that the biomass at maturity is significant and therefore is the ideal candidate for absorption of carbon dioxide.
The English oak is widespread throughout the continent and is known for its longevity (there are also centuries-old specimens). The plant shows a very slow growth.
It is used in different contexts, also thanks to the different variants available in the market which are different in their different rental. In fact, it can find space in rows, as a single specimen, in parks and public gardens and for the formation of barriers.

Ginkgo biloba
Ginkgo biloba, particularly resistant to disease and tolerant to several biotic adversities. It resists cold well, tolerates pollution and suffers only during periods of excessive heat. It is a plant of very ancient origin with primitive characteristics and is today considered a living fossil.
In addition to having several therapeutic properties, it is also an excellent choice in various contexts, including urban. Its peculiar decorative characteristics (fan-shaped leaves, special color) make it immediately recognizable and appreciated.

2. RESISTANCE TO CLIMATE CHANGE
Lagerstroemia indica
It is a plant that adapts very well to a wide range of climates and has a low ripening height. Its most significant decorative feature is represented by its showy flowering (there are many varieties). The stem is also particularly valued from a decorative point of view, it is actually particularly smooth and of a characteristic gray-brown. The plant is not afraid of the cold and also tolerates summer heat very well. It is the ideal candidate for resistance to climate change, precisely because of its rusticity and tolerance to multiple abiotic and biotic adversities.

3. ADAPTATION TO THE URBAN ENVIRONMENT
Morus alba, gold
It is today highly valued in its sterile varieties as an ornamental plant. As it does not produce blackberries, it avoids the necessary cleaning operations during the fruit fall period. The white mulberry has no special soil requirements and is easy to adapt to an urban environment. It does not require much pruning and therefore also has an economic impact due to its particularly low management, making it an ideal candidate for installations in public green areas (in gardens as a single specimen or in small groups).
The white mulberry is historically associated with the production of silk, as the leaves of this plant are Bombyx moris (silkworm) favorite food. It is a medium-sized plant and reaches a height of about 10 meters when ripe.

4. PROTECTION OF THE EARTH / ENVIRONMENT
Acer campestre
This plant, much appreciated by bees for its pollen, is particularly characteristic of the landscape, and in the past it was also one of the species used as a tutor for the wine (wine married to maple). The wood is light, hard and heavy and tends to twist: it is therefore used only for the manufacture of small objects.
It is currently used as an ornamental tree and as a hedge due to its effectiveness in consolidating landslides. It is also suitable for urban design in contrast-filled pollution due to its high absorbency of carbon dioxide and fine dust.
It has a rather limited maturity size and is ideal for replanting degraded slopes, thanks to the properties of its root system.

5. BETWEEN THE PAST AND THE FUTURE
Cupressus sempervirens “Agrimed N.1”
The cypress, Tuscany’s symbolic tree, historically used to define borders, in rows along country roads and to the green areas of the cemetery, was hit by the attack of a fungal pathogen.
Cupressus sempervirens Agrimed n.1 is a cancer-resistant clone of cypress (Seiridium Cardinale), selected and patented by the CNR in 1990, enabling landscape architects to continue to use the species in their interventions.
Its “enlarged” posture and its dense vegetation make it particularly suitable for windbreaks and anti-noise screens. In addition, the dark green color of the leaves and the vigorous growth justify the growing interest as an ornamental plant for use individually or in groups.
