Bog-laurel is a specialized shrub native to cold, acidic wetlands and bogs, requiring consistently moist, peaty, acidic soil to thrive. It is best suited for bog gardens or rain gardens in cool northern climates and is not appropriate as an indoor plant. Keep it in partial shade and maintain soil acidity with peat or ericaceous compost for best results.
