FLOWER SPECIES USED IN AQUATIC LANDSCAPE DESIGN

Abstract

The modern landscape designs are un-conceived without aquatic landscape design. The aquatic plants are essential for assuring a success ful and attractive landscape, conferring life and color even to the smallest landscape designs. The a ttractively part and mystery of water made landscape designs is not always due to the water mi rrors. It’s also due to aquatic species that reveal the beauty of the aquatic landscape design. We can compare this kind of aquatic specie like a „floating island of green”. Constantly the aquati c landscape design is related to the natural aspect of the water designs in the nature. This how we can find the most suitable plants for the aquatic landscape design. The aquatic landscape designs can be made by using some flower species that are adapted to this kind of environmental conditions. The plants c an be chosen not only by their ornamental value but for their need of water and environmental condi tions; witches are more important factors (the type of water landscape designs ‐ lakes, ponds, etc ). After plant habit and biological characteristics the aquatic plants are classified as: natant specie s, submerse species, plasters species, oxygen made species, water lily species. After their origin and placement area, the aquatic species can be classified as: species for humid and swamp areas, s pecies for areas with water depth between (1040 cm depth), water lily area for plant floating (d epth of 50 cm even more). For each place in the aquatic design there is neede d specie, each plant has its own space. In the water lily area ( Nymphaea sp.) can be planted Ranunculus aquatilis , Aponogeton distachyos , floating species ( Pistia stratioides , Eichhornia crassipes , Hydrocharis morsus-ranae , Stratioides aloides ) submerse species ( Myriophyllum spicatum , Ceratophyllum demersum �.a.), before their decorative effect this kind of plants improve the w ater content in oxygene reducing the development of alga in the water. In areas with small depth water it’s recommended species like: Sparganium erectum , Orontium aquaticum , Polygonum amphibium , Butomus umbelatus , Pontederia cordata . In the swamp area are recommended species like: Acorus calamus , Lythrum salicifolium , Iris pseudacorus , Darmera peltata , Lychnis floscuculi . In the humid area : Iris laevigata , Myosotis palustris , Lysichiton americanus , Primula pulverulenta . On the river borders: Carex elata , Polemonium coeruleum , Trollius europaeus , Tradescantia sp., Hosta sp. and ferns. Due to different types of aquatic landscape designs more and more public gardens are choosing this kind of landscapes.
