kalliokasvi

Kalliokasvi is a Finnish term that broadly refers to plants that grow in rocky habitats, such as on cliffs, boulder fields, or in scree slopes. These plants are adapted to survive in environments with thin, often nutrient-poor soils, significant exposure to sun and wind, and fluctuating moisture levels. The term is not a specific botanical classification but rather a descriptive category based on the plant's preferred growing conditions.

Plants thriving in these conditions often exhibit specialized adaptations. These can include deep or extensive root systems to anchor themselves and access water, small or leathery leaves to reduce water loss, and a compact or cushion-like growth habit to withstand harsh weather. Many kalliokasvi species are also well-suited to the high pH levels often found in calcareous rock environments.

Examples of plants that might be considered kalliokasvi include various sedums, saxifrages, certain grasses, and small shrubs. These species play an important role in stabilizing rocky slopes and initiating soil formation by breaking down rock surfaces. Their presence contributes to the biodiversity of alpine and rocky ecosystems. The specific species found will vary depending on geographical location and the type of rock present.
