trailing bellflower 'Stella'


The plant known as Stella, is a charming perennial that graces gardens with an abundance of starry, blue-purple flowers. These blooms are small and bell-shaped, radiating an almost fairy-tale magic as they cascade freely over green, heart-shaped leaves. The foliage forms a dense mat, providing a lush groundcover that is both beautiful and functional, effectively suppressing weeds. Stella's trailing stems are soft and pliable, assisting in the plant's spreading habit. Its flowers are a true spectacle when in bloom, producing a profuse display that can cover the entire plant. This creates a delightful contrast with the lighter green foliage, which has a slight serration on the edges, giving it additional texture. The blooming period of Stella is notably generous, commonly lasting through the warmer months and providing a long season of visual enjoyment. The flowers can also attract pollinators such as bees and butterflies, adding to the dynamic life in the garden. With its charming demeanor, Stella serves as a versatile plant that brightens up rock gardens, borders, and even containers with its cascading growth and vibrant blossoms.

  • water dropWater

    The Serbian Bellflower, commonly known as Campanula poscharskyana 'Stella', should be watered thoroughly when the top inch of soil feels dry to the touch. Typically, this might be once a week, but frequency can vary depending on environmental conditions and the season. During hot, dry spells, watering may need to increase to twice a week. Use enough water to ensure that moisture reaches the root zone; for potted plants, this may mean using approximately one gallon, depending on the size of the pot. In the winter, reduce watering to prevent the soil from becoming waterlogged, but do not let the plant dry out completely.

  • sunLight

    Serbian Bellflower thrives best in full sun to partial shade. An ideal spot for ‘Stella’ would be in a location where it receives morning sunlight and some afternoon shade, especially in hotter climates, to protect it from the intense late-day sun. In cooler regions, it can tolerate more sun, and providing ample light encourages better flowering.

  • thermometerTemperature

    Serbian Bellflower can survive in a temperature range from 40 to 85 degrees Fahrenheit, making it quite hardy. The ideal temperature range for 'Stella' is between 50 and 75 degrees Fahrenheit. It can withstand even cooler conditions, but for optimal growth and flowering, keeping it within this range is best.

  • scissorsPruning

    Prune the Serbian Bellflower to maintain its shape and encourage bushier growth. The best time to prune 'Stella' is in early spring or after it has finished flowering. Deadheading spent blooms will promote a second flowering. Generally, annual pruning to remove dead or damaged stems is beneficial, and occasional thinning can help provide sufficient air circulation within the plant.

  • circleLife cycle

    The life of Campanula poscharskyana 'Stella', commonly known as Serbian Bellflower 'Stella', begins with seed germination, which usually occurs in spring when the temperature and moisture conditions are suitable. The seedlings emerge and establish a rosette of leaves at the soil surface, before developing a robust root system. Throughout the growing season, the plant undergoes vegetative growth, producing more leaves and stems, thus becoming a mat-forming perennial. By late spring to early summer, 'Stella' enters the flowering stage, with star-shaped, lavender-blue flowers blooming prolifically. After pollination, typically involving bees, the flowers produce seed capsules which, when mature, disseminate seeds to propagate the next generation. In autumn, the plant prepares for winter dormancy, with the aerial parts dying back and the roots remaining alive to sprout again in spring, completing its perennial cycle.

      Spring to Summer

    • The most popular method of propagating the Serbian Bellflower 'Stella', which is a variety of Campanula poscharskyana, involves taking stem cuttings. This is typically done in late spring or early summer when the plant is actively growing. To propagate, you should select a healthy stem and cut a piece about 3 to 5 inches long just below a leaf node. Remove the leaves from the lower half of the cutting to prevent decay when planted. Then, dip the cut end into rooting hormone to encourage root development. Plant the cutting in a pot with well-draining soil, watering it enough to keep the soil moist but not waterlogged. Place the pot in a warm spot with indirect light and maintain humidity around the cutting. Roots should develop within a few weeks, after which the new plant can eventually be transplanted outdoors.
