Only Scots pine (Pinus sylvestris) thrives in extreme habitats where there are only hints of the original soil, little moisture and no protection from the sunlight. There are places where shrubs occur in large numbers, similarly as in beech forests. West Carpathian Endemism Pulsatilla subslavica is a unique herb of pine forests which occurs just in Western Carpathians. In April, it blooms with purple flowers together with Sesleria albicans. Its leaves last the whole summer. The Pulsatilla subslavica was botanically described in the area of the Sulov Rocks for the first time. The botanists noticed the difference between the leaves of the local population of Pulsatilla and two other similar species distinguished until then – Pulsatilla slavica and Pulsatilla grandis. Even later, it is possible to find various plant species with nice flowers, for example: Globuria punctata, Phyteuma orbiculare, Bellidiastrum michelii. Original pine forests are on the rocks as remains of larger stands from Ice Ages; therefore, they are called Relict Pine Forests. No other tree could compete with the undemanding pine on the steep rocks.
