Iris Pallada known as Dalmatian IrisHeath-remains were found just by Kopački rit at the cemetery in Bilje. Without a lot of effort, scientists recorded about 140 plant species here. Many of these plants are rare and grow only in a few places in Croatia; others grow only here.
Dalmatian Iris (Iris variegata) belongs to those rare plant species.
White Water lilyThe White Water lily (Nyphaea alba) is one of the most beautiful plants in Kopački rit. You can really enjoy this unique atmosphere when hectares of ponds are covered with these plants in blossom. It cannot be described, only experienced, and of course, recorded with a camera.
Otherwise, the white water lily has thick and rich roots that stags and hinds gladly dig up and eat during the winter.
Smooth Black Sedge (Carex nigra)Smooth Black Sedge (Carex nigra) is a herbaceous perennial plant with underground creeping stems, which can grow up to 20 cm long.
This plant grows in larger or smaller groups in the form of smaller turfs, on mossy soils reactive to acid. The stem is sharp and triple-edged, with a hoarse top, it is noticeably vertical or slightly bent, 10-60 cm high but sometimes even 90 cm high. The leaves are vertical, 2-5 mm wide, they can bend during desiccation. The blossom is 3-13 cm long, the ear ends are male, two or three female ears are situated under them. The Smooth Black Sedge is a geophyte according to life form and it blossoms in May and June.
Flowering rush (Butomus umbellatus)Flowering rush (Butomus umbellatus) is a perennial plant which can grow to be from 60 to 150 cm high. The 1 cm wide leaves are placed on the ground and the pink flowers on top of the stalk blossom from May to August. The Flowering Rush is prevalent throughout Croatia in suitable shallow marsh habitats, ponds and stagnant or slow flowing waters with miry surfaces (adapts to marsh soils which lack oxygen).
This marsh plant is an endangered species according to the Red Book of the Republic of Croatia. By preserving the natural wetlands, we are protecting this species from extinction. The Flowering Rush grows in many places within Kopački rit.
Common Reed (Phragmites australis)This plant can grow to be 5 m high, it grows by shallow waters. A tall and hollow stalk grows from the roots above the surface, every year, and has sharp, long and flat leaves. The 20-25 cm long flower is placed on top of the stalk in the form of a thick ring of brown and red hairs which blossoms from July to September.
Reedbeds serve as a habitat for many marshbirds and offer shelter and protection for small fish in deeper waters. Dry reed stalks have a multifunctional role in the architecture of this area, and were most frequently used for covering roofs in traditional architecture.
Graceful Cattail (Typha laxmannii)Is a light plant between 70 and 120 cm high. The leaves are usually open by the base, while the edges are ear-shaped. The flat part of the leaf is 2–7 mm wide. The flowers are usually surrounded with hair or scales arranged in two thick cylindrical blossoms, females are placed in the lower part and males in the upper part. The male and female parts of the blossom are separated 1–6 cm. The female blossom is 4–9 cm long, whiles the male blossom is 2–4 times longer. The blooming stalks are shorter than the leaves. This plant grows by water and in water, and also requires sandy soil.
The Graceful Cattail was first recorded in the year 2000, in the form of a small population existing only in Kopački rit. It is listed in the Red Book of the Republic of Croatia and belongs to critically endangered species.
Paleyellow IrisBirds are not the only species that Kopački rit is famous for. Different plant species grow and blossom here, of which some are beautiful. The Paleyellow Iris is one of them. They can only be found in a few places in Central Europe and Croatia, namely just a few sods.
At the beginning of June, large areas, even a couple of hectares, in Kopački rit are often covered with beautiful blue flowers of this type called Siberian Iris (Iris Sibirica).
