The particularly favourable mild climate of the Nature Park encourages the growth of sub-Mediterranean plants, shrubs, flowers and particular oak, beech and ash trees including, for example, the Downy Oak. Unusual flora flourishes on the dry meadows of the high pastures and chestnut trees grow well in the shadow of rock-walls while the mountain slopes are covered with pine forests mixed with juniper trees. Woods withs lower trees and birch, hazel-nut and beech trees fill side valleys and other well-watered places.
The Texel Group Nature Park is home to a good number of protected flowers and plant species including so-called “cowbells”, the Dolomite columbine, the Giant Snowdrop, the Fire Lily, several orchids, Daphne Mezereon, carnations, various herbs, primulas, cowslips and primroses, Alpine violets, enzian, yellow irises, yellow and white water-lilies, reed-mace, crowned rampion, Dolomite yarrow, Edelweiß and many more.
