Mini Marvels™ Midnight Carpathian Bellflower (Campanula carpatica ‘Midnight’) is a compact perennial renowned for its deep violet-blue, bell-shaped flowers that appear in late spring and continue through much of the summer. Growing just 6 to 8 inches high and spreading 10 to 12 inches, this petite wonder brightens up rock gardens, borders, and containers with minimal fuss. Its lush green foliage provides the perfect contrast for the rich blooms, ensuring the plant remains eye-catching throughout the season. As a member of the Mini Marvels™ series, it delivers strong garden performance in a charming, space-saving package.
Mini Marvels™ Midnight resists deer browsing and tolerates occasional dry spells once established. Hailing from the Carpathian Mountains in Europe, it adapts easily to a variety of garden styles, from cottage landscapes to more formal borders. Pollinators, especially bees and butterflies, love the nectar-rich flowers, so expect plenty of activity in your garden. Whether you choose mass plantings for a dramatic effect or use it as a tidy edging plant, this bellflower adds long-lasting color in sunny to partially shaded locations.
Mini Marvels™ Midnight Carpathian Bellflower Care
Plant in well-draining, moderately fertile soil and water regularly during the first few weeks to help the roots settle in. For best results, place it in a spot that receives at least four hours of sunlight daily, although it can handle more direct sun in cooler climates. A light, all-purpose fertilizer in early spring helps maintain robust growth and continuous flowering. Keep the soil slightly moist but avoid waterlogged conditions.
Light pruning, such as deadheading, encourages additional blooms and keeps the plant looking fresh. If any stems become leggy, a simple trim near the base promotes new growth. Container-grown plants may require extra watering, especially during extended dry periods. Winter care typically involves clearing away old, faded stems in early spring rather than late fall to protect the crown.
Mini Marvels™ Midnight Carpathian Bellflower Spacing
Space each plant about 10 to 12 inches apart in borders or mass plantings for a lush, cohesive display. In smaller gardens or tight spots, leaving at least 8 inches between plants ensures enough airflow and healthy growth. If potting, choose a container at least 10 inches in diameter to accommodate the root system and enable it to thrive.
