trailing bellflower 'E.H. Frost'


Campanula poscharskyana 'E.H. Frost', commonly known as the trailing bellflower or Serbian bellflower, is a delightfully charming plant that features a cascade of heart-shaped leaves, which often have a lush, vibrant green color. The foliage provides a lush backdrop for the striking flowers. The blooms are star-shaped with a radiant white hue and a subtle lavender blush, typically with five pointed lobes that create a whimsical starry pattern. These flowers possess a gentle, yet enticing beauty, which is further highlighted by the contrast between their pastel tones and the greenery. The blossoms are borne in loose clusters, creating a soft, frothy appearance as if a light dusting of snowflakes had settled atop the foliage. The trailing bellflower boasts a vigorous and spreading habit, often forming a low, mat-like ground cover, which practically makes it a living carpet of foliage and flowers during its blooming season. This plant's effusive charm and cascading form make it particularly well suited for embellishing rock gardens, wall crevices, or for draping over the edges of containers, where its beauty can be showcased and adored.

  • water dropWater

    The Serbian Bellflower, as Campanula poscharskyana 'E.H. Frost' is commonly known, prefers evenly moist soil, but it should not be waterlogged. It is best to water this plant when the top inch of soil feels dry to the touch. Water the plant thoroughly, allowing the water to soak in and reach the roots, but be sure to avoid standing water. In hot conditions or when the plant is actively growing in spring and summer, you might need to water once or twice a week, using about 1-2 gallons per plant, depending on size and soil conditions. During cooler months or when the plant is dormant, reduce the watering frequency.

  • sunLight

    Serbian Bellflower thrives in full sun to partial shade. It performs best in a spot that receives at least 6 hours of sunlight per day. However, in areas with very hot summer sun, it benefits from light afternoon shade to prevent scorching its leaves. Morning sun with dappled afternoon light is ideal for promoting a healthy growth and abundant flowering.

  • thermometerTemperature

    Serbian Bellflower is hardy and can withstand a range of temperature conditions. It prefers a temperate climate and thrives in temperatures between 60 to 75 degrees Fahrenheit. It can survive minimum temperatures down to about -30 degrees Fahrenheit and is generally hardy in USDA zones 3 to 8. Consistent temperatures within the ideal range promote the best growth and flowering.

  • scissorsPruning

    The Serbian Bellflower benefits from pruning to maintain its shape and encourage denser growth. Prune in the spring just after new growth begins, cutting back any dead or overgrown stems. Deadheading, or removing spent flowers, promotes additional blooming and should be done regularly throughout the flowering season. Major pruning is not often necessary; however, a light trim can be given after the main flowering period to tidy up the plant and remove any straggly growth.

  • circleLife cycle

    The life of Campanula poscharskyana 'E.H. Frost', commonly known as 'Serbian Bellflower', begins with seed germination, which occurs in moist, well-drained soil with adequate light exposure. The seedlings then develop into rosettes of heart-shaped leaves, from which trailing stems emerge, spreading outward or downward depending on their support. Vegetative growth continues with leaves and stems becoming more robust, and the plant may also spread through runners. Flower buds form, usually in late spring to early summer, leading to star-shaped, light blue to white flowers that bloom for several weeks. After pollination, typically by bees, the flowers develop into small capsules containing seeds, which get dispersed to start new plants. Finally, the plant enters dormancy in winter, with the foliage often dying back, before re-emerging in spring to repeat the cycle.

    • Propogation time

      Spring to early summer

    • Propogation: The Serbian Bellflower 'E.H. Frost', a variant of Campanula poscharskyana, is commonly propagated by division, which is the most popular method for this perennial plant. The best time for dividing Serbian Bellflowers is in the spring or early fall when the plant is not in bloom. To propagate by division, one should carefully dig up an established clump of the plant and then gently separate the clump into smaller sections, making sure that each section has a portion of the root system along with some shoots. These sections can then be replanted in well-prepared soil at the same depth they were growing previously, spaced about 12 inches (or about 30 centimeters) apart to allow sufficient room for growth. After planting, it's essential to water the new divisions thoroughly to help establish them. The divisions will typically take root and start to grow quickly, given adequate moisture and light.
