Founded as a state-owned enterprise under the municipality of Grosseto, it was taken over by Giorgio Tesi Group in 2011. Il Terzo is located in Roselle, a few kilometres from Grosseto, in the heart of the Maremma region of Tuscany. The nursery has 70 acres of open field cultivation and 20 acres of container stock. It specialises in the production of plants typical of Maremma and the Tyrrhenian coast, in all sizes, from small 3-10 litre containers to more substantial specimens, including: Arbutus Unedo, Elaeagnus, Phillyrea Angustifolia, Rhamnus Alaternus, Pistacia Lentiscus, Quercus Ilex, Quercus Suber, Pinus Pineaster, Pinus Halepensis, Viburnum Tinus, Viburnum Lucidum, Olea Europaea, Myrtle, Specimens, Cupressus Sempervirens Pyramidalis (up to 11 m in height), Cupressus Sempervirens Agrimed (up to 7 m in height) and Pinus Pinea (8-10 m, 80-100 in circumference).

Noteworthy items in recent years include the new production of these varieties shaped like balls (page…) and parachutes (page…), which are currently very popular on the market. An important research project is being conducted in the branch, together with the National Research Council Institute for Plant Protection, which has led to experimentation with cypress clones resistant to the fungus known as Seiridium cardinale, or more commonly “Cypress canker”, such as Bolgheri, Agrimed, Mediterraneo and Italico, for which the Giorgio Tesi Group has exclusive production and marketing rights worldwide. These varieties are available from the branch and from our centre in Pistoia, in sizes ranging from seedlings to mature trees.
