The constructions from glass and metal occupies about
3800 m². The precinct shelters remarkably plants collections (approximate
2600 taxa) native especially of sub-tropical, tropical and equatorial
zones of the globe, from all the continents. Their distribution is realized
taking into account well defined criteria: bio-geographic, taxonomic,
The complex includes 12 greenhouses, each of them having
their characteristics and containing various plants species. Greenhouses
3, 4, 5, 6, 10, 11 and 12 are used exclusively for scientific research
and prepare reproducing material. That is why these greenhouses are
not opened for the visitors.
No. 1 greenhouse
No. 1 greenhouse contains the xerophilous plants collection.
The species placed in the central space of the compartment creates a
heterogeneous taxa association, presenting arboreal aspect and corresponding
to one elective criterion: all of them are species originating in zones
presenting sub-tropical (Mediterranean) climate (they grow in natural
conditions in the territories situated around the Mediterranean Sea;
also by climatic analogy, in the NV of California, Chile, South Africa).
Most of these taxa are very well known: Mediterranean fan palm, olive
tree, pomegranate, fig tree, carob, laurel tree, oleander, rosemary,
cypress, bay, butcher’s broom, etc. Here, the valuable collection
of plants with bulbs, rhizomes and bulbotubers can also be admired,
collection including taxa prevalently included in three botanic families:
Liliaceae, Amaryllidaceae and Iridaceae.
A positive impression is induced by the decorative qualities of the
great inflorescences, persisting in time of the African lily and clivia
species. Solitary or grouped flowers, in pastel colours of Zephyranthes
candida, Zephyranthes grandiflora and also the colours,
forms and size of the leafs of some species as Haemanthus albiflos
(ear of the elephant), Ledebouria socialis, Eucomis
comosa are completing the image of no. 1 greenhouse.
No. 2 greenhouse
No. 2 greenhouse presents a heterogeneous structure.
The majority of the representatives belong to the Palmae botanic family.
These and other specimens situated in other spaces of the greenhouses
complex (no. 8, 9 and 11) forms the palms collection of the Botanic
Garden. The date palms, Mediterranean fan palms, ornamental palms (originating
in California), Phoenix roebelenii (native from India and China),
Caryota mitis (originating in Malaysia) represents only few
of the 50 species that are constituting the palm collection. The greenhouse
includes also representatives from Cycadaceae family, primitive
forms in actual gymnospermes background. The most spread species of
the Cycas genus is Cycas revoluta, originating in
Japan. The collection includes other representatives of the family:
Ceratozamia mexicana (originating in Central America), African
species Encephalartos ferox and Stangeria eriopus.
Some specimens from the enumerated genera (Cycas, Encephalartos,
Ceratozamia) have flowered in the greenhouses of Botanic Garden
Iasi, phenomenon presenting a rare occurrence in culture conditions.
No. 3 greenhouse
In no. 3 greenhouse are cultivated plants originating
in the tropical zones of the globe.
Here can be admired the epiphytes collection – plants presenting
a particular way of life, significant for the capacity of adaptation
imposed by the conditions characteristic to their natural environments
(for example, rainforests where the light is showing a deficit).
The orchids have a wide spreading area and can be met preponderantly
in tropical regions of Africa, America and Asia. These plants attracts
especially by their perfume, colour, forms and proportions. In our greenhouse
can be admired over 60 species and hybrids, most of them epiphyte, some
presenting a series of adaptation curiosities: the existence of foliar
bulbs assuring the water reserves or roots exposed to the air presenting
an tissue that absorbs the pluvial water.
Most of the epiphytes exposed in no. 3 greenhouse are species from Bromeliaceae
family, the visitor being impressed by the decorative aspect of their
leafs. Beside them, can also be remarked a series of epiphytes and lianas
from Araceae family (famous by the variety of size and colouring
of leafs), ferns (Pteridophyta – some having tropical
origin) and insectivorous plants. The last of them are distinguishing
by their adapting qualities transposed in the nutrition mode: because
they are usually living in environments poor in nutrients, they are
completing the "food" obtained by photosynthesis from substances
having mineral origin with another type of "food", by organic
origin, obtained through the decomposition process of the substances
that are composing the body of some animals, especially insects.
From 535 species of carnivorous plants known in the globe flora, in
Romania only 10 are growing (from Drosera, Aldrovanda,
Pinguicula and Utricularia genera).
Also, the greenhouse shelters collections of plants decorative by leafs:
Begoniaceae, Commelinaceae families etc.
No. 4 greenhouse
No. 4 greenhouse shelters collections of plants originating
in the tropical zones of the globe, notable by the ornamental aspect
of the flowers and leafs.
For example, Anthurium scherzerianum presents an inflorescence
very attractive by its configuration and bright colouring (red –
carmine) of spadix and spathe. Also, the beauty of A. hookeri,
A. leuconeurum and A. warocqueanum taxa is assured
by certain particularities of their great leafs, intense green coloured
and having velvety aspect.
In no. 4 greenhouse can also be admired over 20 taxa from Calathea,
Ctenanthe, Maranta, Stromanthe and Thalia
genera (Marantaceae family), over 15 cultivars of Codiaeum
variegatum var. pictum (Euphorbiaceae family)
and a series of taxa from Liliaceae family.
Additionally, the visitors can admire here perhaps the most interesting
tropical plant, Mimosa pudica, species attracting by its delicate
pinnate leafs which are proving a surprising sensibility, executing
nyctinastic (in accordance with the alternation day / night) and seismonastic
movements (provoked by light touches).
No. 5 greenhouse
No. 5 greenhouse attracts visitor's interest in the winter
season; it is destined to protect some bushy species – azaleas
Azaleas have the origin in the mountain regions of S-E Asia, only few
originating in North America and Europe. In the Botanic Garden of Iasi,
35 varieties of azalea can be admired. The shrubs are presented in cultivation
vases (pots or pails) and have a size until 2 m height. The leafs are
persistent and the flowers generally displays a great diversity of aspects:
trumped or urceolate, simple corollas or presenting many ranges of petals,
having undulated or fringy petals margins, solitary or grouped and a
very varied line of colours: bright red, brick – coloured, violet
with white indented margins, pink knurled with white or immaculate white.
The plants composing this collection flower in December – March
Camellia genus includes approximately 80 species naturally
spread in S-E Asia. Among that, the tea shrub (C. sinensis),
originating in China, is one of the most popular species. Our collection
includes 10 varieties of Camellia japonica species. Its origin
is extreme – oriental (Korea, Japan, N of China), where it presents
a bushy or arboreal aspect (until 15 m height). The leafs are evergreen,
bright and the flowers have big size, waxy petals arranged in scales
forms and are varied coloured (white, red, pink or immaculate).
No. 6 and 7 greenhouses
No. 6 and 7 greenhouse offers the appropriate background
for the cultivation of species that are composing the succulent plants
collection. Although these species belongs to different botanic families,
they have a series of essential commune characteristics: retains and
accumulates water in their vegetative organs.
Most of the cactuses cultivated
here are specific to the desert or semi – desert areas from North
and South America.
The species from Cactaceae botanic family presents a interesting
geometry of forms and diverse particularities regarding the aspects
and the insertion of prickles, the delicacy and the colouring of the
flowers. Between all these, we can remark species from Astrophytum,
Lobivia or Rebutia, Gymnocalycium genera
Other representatives of Echinocereus, Echidnopsis
and Mammillaria genera are completing the general aspect of
no. 6 and 7 greenhouses.
The economic value of plants as the Cactaceae is well known.
