We were the first in North America to grow species such as Glossostipula concinna, Zinowiewia matudae, Lozanella enantiophylla, Weinmannia pinnata, Meliosma matudae, Cedrela salvadorensis, and Heberdenia penduliflora. Over the decades, the collection has matured into a realistic representation of cloud forest habitat.
One of the important aspects of Mesoamerican civilizations was their development of a form of writing, so that Mexico's written history stretches back hundreds of years before the arrival of the Spaniards in 1519.This era before the arrival of Europeans is called variously the prehispanic era or the precolumbian era.he Olmec first appeared along the Atlantic coast (in what is now the state of Tabasco) in the period 1500-900 BC. The Olmecs were the first Mesoamerican culture to produce an identifiable artistic and cultural style, and may also have been the society that invented writing in Mesoamerica.
