The linden tree (lipa) is a sacred Slavic tree whose symbolism has been preserved in legends, stories and written history until present day. It is a honey bearing medicinal plant whose flowers are used in tea-making, one of the oldest known beverages for health and healing. The linden is an especially prized wood in carpentry and turnery. The linden is indigenous to Croatian forests and can be found in all parts of the country, a strong, tall tree that can live to an age of several hundred years.
Motif on the reverse: the centre of the coin features a stylised image of the endemic Velebit Degenia. The inscription "VELEBITSKA DEGENIJA" (Lat. DEGENIA VELEBITICA) is displayed above the image, circularly along the edge of the coin. The minting year is positioned centrally along the lower edge.
The Velebit degenia, with its narrow leaves and yellow flowers is endemic to Croatia. This extremely rare plant is also the only existing species of the degenia genus. It grows in the notches and stone blocks on a few sites on Velebit mountain. It is named after the Hungarian biologist Arpad Degen, who discovered it in the summer of 1907.
