Horticulturists understand azaleas as a number of species
of the genus Rhododendron that shows special characters: five
or six stamens comparative to most species that have 10 stamens, leaves
with softer underside and microscopic scales presenting spherical shape.
In the greenhouses of the Botanic Garden "Anastasie
Fatu" from Iasi 35 varieties of Rhododendron simsii are
grown. The diversity of colors of these flowers varies from the pure
white of the 'Petrick Alba' and 'Pax' varieties to
the cheerful pink of the 'Vervaeneana' variety, to the well-known
purple of the 'Concinnum' variety or the intense red of the
'Superba', 'Europe' and ‘Rolco' varieties.
Camellias are plants native to tropical and subtropical regions of Southeast
Asia, China and Japan and the number of species in this genus is estimated
at about 120. They are shrubs or small trees that generally prefer areas
with high altitude.
Collections of the Botanic Garden from Iasi include
12 varieties belonging to the Camellia japonica L. species.
Among them, there are some very old varieties as 'Alba Simplex'
('Snow Goose') dating from 1819 and 'Alexander Hunter'

red ('Chandleri Elegans').
Tropical areas are known as the richest in species
and zone from where come many ornamental plants loved by amateurs. Here
originated the majority of the over 850 species of the genus Ficus
(F. benghalensis, F. benjamina, F. elastica,
F. lyrata, F. platypoda, F. rubiginosa, F.
sagittata) known for their content in latex and the adventitious
A very popular group of plants is represented by crotons
(originating from Malaysia). Under this name are known varieties with
colorful leaves of Codiaeum variegatum var. pictum
(Loddiges) Müller Argoviensis, Botanical Garden's collection including
25 varieties such as ’Goldfinger’, 'Goldstar',
'Norma', 'Petra', 'Pictum'. Part of the same

Dracaena genus, with spreading from Africa
to Asia and even Central America, is represented by some varieties with
variegated leaves of D. deremensis and D. marginata
Collection of botanical garden ferns grouped large
specimens of Asplenium nidus or that very small from the Selaginella
genus. Specimens of Nephrolepis exaltata ‘Hillii’
are attractive by the shape of leaves, those of Pteris cretica ‘Albolineata‘
by variegated leaves and Adiantum by the very fragile appearance.
Perhaps the best-known interior fern is Platycerium bifurcatum,
whose divided leaves remember the look of elk horns.
In the collection of the Botanic Garden of Iasi there
are over 60 species and hybrids, many epiphytic (Cattleya labiata,
Lycaste aromatica, L. deppei, Stanhopea insignis,
S. hernandezii) and specimens that grow well in soil (Paphiopedilum,
Cactus collection of the Botanical Garden brings together
species ranging from very large to very small, as are those of the genera
Chamaecereus, Dolichotele, or with suggestive shapes
(Astrophytum), "fluffy" aspect (Espostoa,
Pseudoespostoa), colorful flowers (Aporocactus), "monster"
aspect or obtained by cutting.
Also from arid areas of Central and South America are
large specimens as Nolina recurvata, Pedilanthus tithymaloides
‘Variegata’ and varieties of agave.
African Flora is represented by very different species
as Euphorbia canariensis, E. leuconeura, E. milii,
E. tirucalli, E. trigona, E. caput-medusae,
Portulacaria afra, Aeonium arboreum, and A. domesticum
The Begonia genus, with approximately 1500
species, is one of the largest in the world. The most known begonias
are herbaceous plants but there are also taxa presenting a sub-arbutus
Although begonias are naturally widespread in the tropical
and subtropical areas of Africa, Asia and America, still the highest
number of species occupies the wet mountain forests from South America
Botanical Garden collection present annual species
(B. hirtella), at which the multiplication is made just by
seeds, and also B. tuberhybrida, known for their beautiful
Most taxa in the collection show a variety of leaf
size (15-20 cm - Begonia ricinifolia or B. digitata
or 2-3 cm - B. foliosa). Leaves chromatics combine in very
attractive ways different shades of green - from very intense tones
(B. listada) to spring colors (B. ulmifolia) and even
glaucescent (B. rex 'Escargot') - to warm tones of ocher, brown
or garnet (B. rex varieties). The corrugated appearance of
the leaves of B. masoniana surprise by rigidity and roughness.
Bromelias is a family of plants with over 3000 species,
widespread in South America, Chile and Argentina to Central America
and the Caribbean. The greatest number of species is found in Brazil,
while in West Africa there is only one species (Pitcairnia feliciana).
These plants can be found from sea level to 4300 m, in extreme habitats
ranging from dry and cold deserts to rain forests and even cold mountainous
The best known species is pineapple, whose varieties
with variegated leaves have a decorative value. Botanical Garden's collection
includes other decorative bromeliacee both by the leaves and the flowers:

Peperomia argyreia, P. caperata, P. c. ‘Red
Riple’, P. clusiifolia ‘Variegata’,
P. griseo-argentea, P. obtusifolia, characterized
by a spiciform inflorescence. The decorative role of leaves is show
in the vegetable arrangement covering the center of exhibiting greenhouse.
