Bog-laurel is a delicate alpine and subalpine shrub that requires consistently moist, acidic soil and cool temperatures to thrive. It performs best in rock gardens, bog gardens, or naturalized mountain landscapes with partial shade and excellent drainage in raised peat-based beds. Avoid warm, dry conditions and note that all parts of the plant are toxic if ingested.
