Chronology
- I Period (1912-1914)
The formation of the gardens structure and strategy. A big part of that time introduced plants (about 580 species) are still preserved to this day. From the beginning 6 Phyto-geographical departments had initially been created in the Batumi Botanical Garden.
- II Period (1915-1934)
Coincides with I World and Civil wars.Plant introduction was connected with difficulties. From the inventory materials by that time 917 species, varieties and forms had been introduced.
- II period (1935-1941)
During this period the introduction activities as well as the department of the introduction and acclimatization were supervised by a prominent scientist and an expert of humid subtropics Sergei Hinkul.The collection of the Garden was increased up to 1302 species.
- IV Period (1941 – 1950)
The years of the World War II practically all contacts with other botanical gardens were terminated and introduction activities were ceased. The severe winter of 1945-1950 (-8,6°C) also made an impact on the decrease of the collection, it was reduced by 212 taxa.
- V Period (1951-1965)
Coincides with the period of transition of the Batumi Botanical Garden under the authority of the Georgian SSR Academy of Sciences. The period saw the activation of the work on the issues of introduction, floristic composition, origin, systematic specification, etc. According to the data of 1th January, 1965 the collection of the Garden comprised1679 exotic taxonomic units.
- VI Period (1965-1985)
The period was distinguished by a number of long sever winters (1967,1972, 1976, 1980, 1985) that mainly caused the damage of newly introduced species. By 1 January, 1986 the collection of woody plants increased by 358 taxa and comprised a total number of 2037 taxa including 375 genera of 112 families.
- VII Period (1986 -2008)
During this period hard political-economic situation in the country since 1990s made a negative impact on the process of plant introduction.The fact that since 1998 the Batumi Botanical garden has been the member of the Council of the Botanical Gardens Conservatio International (BGCI) greatly promoted the activation of the work in elaboration of theoretical basics and methods of plant introduction and acclimatization, deep systemic study of the wild and cultivated flora as well as elaboration and implementation of innovated modern technological methods in the direction of plant protection.
- VIII period
From 2008 till present the specification of the taxonomic composition of the plant collection (trees and shrubs) families and 532 genera.According to the phyto-geographical departments and collections they are distributed in the following way: East Asian -710, North American – 217, Eoropean-99, Transcaucasian Humid Subtropics -89, Himalayan-74, Australian -70, South American-22,Mexican-17, New Zealand-15, South Africa-1: cultivated forms:citruses-55, camellias-17, roses-50, maple-18, other cultural forms-46.
