Temperature Requirements
Campanula aparinoides Pursh var. grandiflora Holz. prefers cool temperatures and is tolerant of frost. It grows well in USDA hardiness zones 3 to 7, which have an average annual minimum temperature of -40 to 0 degrees Fahrenheit.
Soil Requirements
This plant prefers moist, well-draining soils that are rich in organic matter. It grows best in soils that are slightly acidic, with a pH range of 5.5 to 6.5. Additionally, it can thrive in soils that are sandy or clayey as long as they are fertile and well-draining.
Overall, Campanula aparinoides Pursh var. grandiflora Holz. requires moderate sunlight, cool temperatures, and moist, well-draining soils to grow and thrive.
Cultivation Methods
Campanula aparinoides Pursh var. grandiflora Holz, also known as trailing bellflower, thrives in moist, well-draining soil with partial shade to full sun exposure.
Sow seeds in the early spring or propagate through division in the fall or spring season. To maintain the plant's health, avoid overcrowding by spacing 12-15 inches apart.
The trailing bellflower is a low-maintenance plant that adapts well to a variety of growing conditions, making it ideal for beginners and experienced gardeners alike.
Watering Needs
The trailing bellflower requires moderate watering during hot or dry weather conditions. The soil should remain moist, but avoid overwatering, which may cause root rot.
To ensure proper hydration, always water at the base of the plant and avoid wetting the leaves or flowers. Use a watering can or hose nozzle on a low pressure to deliver water to the soil directly.
Fertilization
While the trailing bellflower does not require much fertilizer, an occasional application of a balanced, slow-release fertilizer can help stimulate growth and encourage flowering.
Fertilize the plant in the early spring, using a recommended dosage according to the instructions on the label. Be sure to apply the fertilizer evenly around the plant's base and water thoroughly afterward.
Pruning
Pruning the trailing bellflower is not always necessary, but it can extend the blooming season and promote a more compact, bushy growth habit.
In the early spring, cut back any dead or damaged stems to the base of the plant. After blooming, trim back the spent flowers to encourage new growth and prolong blooming. The trailing bellflower will readily respond to pruning with vigorous growth the following season.
Propagation of Campanula aparinoides Pursh var. grandiflora Holz.
Campanula aparinoides Pursh var. grandiflora Holz., also known as the greatflower harebell, is a hardy perennial herb that is native to North America. Propagation of this plant can be achieved through various methods, including:
Seed propagation

Root cuttings should be taken from healthy, mature plants in late winter or early spring while they are still dormant. The cuttings should be about 2 inches long and planted in a pot or garden bed filled with a well-draining soil mix. Water the cuttings regularly but avoid overwatering as this may cause rotting. The cuttings should develop roots within 4 to 6 weeks.
Overall, Campanula aparinoides Pursh var. grandiflora Holz. can be propagated successfully through various methods, including seed propagation, division, and root cuttings. Proper care and attention should be given to the propagated plants to ensure their successful establishment and growth.
