This square is only a couple of minutes away on foot from the botanical garden of Palermo, where an equally large specimen of the same kind of tree can be found.The biggest Ficus macrophyla in Palermo and Europe is the Specimen in Piazza Marina, Garibaldi Gardens, planted in the year 1863, with 10000 cubic meters of vegetal matter, Height 25 mt and a Trunk Girth / Central Body of 40 mt.
I propose to consider a new method of measurement: not the Girth of the Trunk, Architectures of these kind of Trees are not possible to measure in this way.
I consider the Central Body (CB) that is a huge geometry of columns, roots and branches, typical of the species.
For what concern the biggest Specimens it is possibile to measure also the Total Perimeter (TP), considering marginal pillars.
Through this method I've measured the biggest ficus in Palermo:
Piazza Marina | Central Body: 40 meters; Total Perimeter: 70 meters;
Botanical Garden | CB: 28 meters; TP: 87 meters;
Villa Whitaker a Malfitano | CB: 30 meters (a unusual geometry so CB is the same as TP);
Palazzina Cinese | CB: 27 meters;
Palazzo dei Normanni | CB: 18 meters.
The girth of the tree is more than 30.00 m measured at a height of 1.30 m (2012, Tiziano Rootman Fratus). As this tree is a tree with multiple trunks, the girth can be larger than what would be expected of the tree of this age. Its height is around 25.00 m (2012, measurement method unknown, Tiziano Rootman Fratus).
