Species Database
Comprehensive catalog of cold-tolerant plants for container cultivation
Database Overview
Our species database contains detailed information on over 200 cold-resistant plant varieties suitable for Nordic balcony environments. Each entry includes hardiness ratings, growth characteristics, and specific care requirements.
Data is compiled from field observations, controlled testing, and verified through multiple winter seasons. Regular updates incorporate new discoveries and cultivar developments from research collaborations.
Classification System
Hardiness Zones
Species are categorized by USDA Hardiness Zones, indicating minimum temperature tolerance. Zone 3-4 species are most suitable for extreme Nordic conditions, withstanding temperatures to -40°C.
Growth Habit
Classification includes growth patterns: compact, spreading, upright, or trailing. This information helps select appropriate species for available balcony space and desired visual effect.
Container Suitability
Each species is rated for container compatibility based on root system characteristics, mature size, and adaptation to restricted growing spaces. Ratings guide appropriate container selection.
Search Parameters
Database search functionality allows filtering by multiple criteria: hardiness zone, growth habit, bloom time, foliage type, and container size requirements. Advanced filters help identify species matching specific balcony conditions.
Each species profile includes photographic documentation, growth data, and field observation notes. Survival rates and recovery patterns are documented to provide realistic expectations for plant performance.
Data Sources
Research Collaboration
Species data is gathered through partnerships with botanical gardens, research institutions, and field observation networks. This collaborative approach ensures comprehensive coverage and verified information accuracy.
Field trials conducted across multiple Nordic locations provide region-specific data. Controlled environment testing supplements field observations, allowing precise measurement of cold tolerance thresholds.
