Various types of vegetation grow in the wetlands.
Depending on salt concentration, different halophilic plants can be found, like rushes (Juncus spp.), the Sea Aster (Aster tripolium), the Golden Samphire (Inula crithmoides), slender grasswort (Salicornia fruticosa), Salsola soda, saltcedar (Tamarix spp.).
Various species of hydrophilic plants grow depending on the water depth: the common duckweed (Lemna minor), the white water lily (Nymphaea alba), the spatterdock (Nuphar lutea), the common reed (Phragmites australis), the bulrush (Scirpius palustris), the narrow-leaved cattail (Typha angustifolia).
Hygrophilous plants grow near the water but usually out of it. Only a few hygrophilous trees grow in Neretva Delta, like poplars (ulus spp.) and willows (Salix spp.).
The plants which grow in the areas surrounding the wetlands and on the hills belong to a xerothermic (adapted to dry and hot environment) evergreen vegetation called matorral or macchia characterized by the presence of holm oak (Quercus ilex) and Aleppo pine. Where limestone rock appears, the matorral turns into garrigues (“Gariga”), a Mediterranean association of herbaceous plants and shrubs.
