Pearl White, or Carpathian Bellflower, is a perennial flower native to Europe. It offers profuse white, bell-shaped blooms from June through August on a compact, bushy habit of 8-10" tall and 10-12" wide. Campanula flourishes in full or partial sun with moderate water and minimal care. It is particularly well-suited to containers, garden beds, and compact landscapes, where it adds dense growth and whimsy. Bring bees, butterflies, and hummingbirds to the yard with Pearl White's low-maintenance, attractive flowers and enjoy them cut in floral arrangments. This plant is hardy in zone 3-8 and tolerates heat and drought with some shade. Pair White with Campanula Pearl Deep Blue for contrast and variety.
Pearl White Selling Tips
Sell Pearl White to customers looking for a low-maintenance perennial for a container or cut-flower garden. This plant offers many benefits, including beautiful flowers throughout summer, a compact habit, and cold-hardiness to zone 3. Campanula brings pollinators to the yard or patio and is an attractive cut flower in arrangements. Create a stunning, low-maintenance cottage landscape by growing Campanula Pearl alongside Geranium, Dianthus, Salvia, Coreopsis, and Petunia.
Coach Your Customer
1. Space seedling plugs 8-10" apart in well-drained soil in full or partial sun. Plant this flower in spring or fall.
2. You may apply a balanced fertilizer in the spring, but Campanula will do okay without it.
3. Pinch back stems in early summer after the first blooms to encourage bushy growth and deadhead spent blooms to promote continuous blooming.
4. In cold climates, mulch plants to protect roots from freezing temperatures.
General Growing Tips For Your Seedling Tray
For best results with Pearl White, plant one seedling plug per 4-inch or three per 10-inch container. Use well-draining soil with a pH of 5.5-6.5, EC of 1.0-2.0 mS/cm (2:1), and moderate feed (150-200 ppm N) of a NPK fertilizer with a ratio of 20-10-20. Provide temperatures at 60-65 daytime and 50-55 nighttime and don't pinch or use PGRs. This plant requires 12-14 hours of bright light daily. Watch for slugs, snails, aphids, spider mites, Botrytis, Powdery Mildew, Pythium, Leaf Spot, and Fusarium Wilt.
Flowering
White bell-shaped flowers bloom from June through August.
Pinching
This plant doesn't require pinching during finishing. Coach customers to pinch it back after the first blooms begin to die off to promote bushy, continuous growth.
Spacing
Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant and easy access to scout for pests and water efficiently. We recommend giving 12-18" between containers and adjusting as needed for temperature, humidity, lighting, and your greenhouse layout.
Height Control
Control height and encourage bushy plants by providing adequate light (12-14 of hours bright indirect light) and growing seedling plugs in cool temperatures (60-65 daytime). These measures should keep Pearl White from becoming leggy. You may use Bonzi or Sumagic according to the label instructions if necessary. Campanula is naturally bushy and dense, but you may pinch every few weeks once the plants are 3" tall if needed.
Pests
You may see slugs and snails in the garden or greenhouse. Watch for aphids and spider mites in the greenhouse. Implement a thoughtful Integrated Pest Management plan to prevent pests from damaging your seedling plugs.
Aphids are small, soft-bodied insects that cause damage by sucking sap from plant tissue. They reproduce quickly and are particularly attracted to young growth. Curling and yellowed leaves, stunted growth, and stickiness on leaves are signs of an infestation. These insects also spread diseases and reproduce rapidly. Use biological controls or horticultural oils to discourage and kill aphids.
Spider Mites are tiny pests that cause stippling, yellowing, and webbing on foliage by feeding on plant sap. They flourish in warm, dry environments. Use correct water and fertilizing practices; over-fertilizing can attract spider mites. Proper humidity levels, predatory mites or ladybugs, and insecticidal soaps or oils may prevent or address a spider mite infestation.
Slugs and snails eat foliage in the garden or greenhouse. In the greenhouse, prevent damage by keeping snails and slugs away from plants with copper tape, bait, or natural predators. Although it's laborious, picking these pests off plants is effective. They most enjoy moist, dark areas, so keep the area around plants clean and free of debris and implement proper watering practices that allow the soil to dry between waterings and don't allow standing water.
Prevention is the best solution for pests! Use sanitary practices and provide adequate airflow and light and proper watering.
Disease
Watch for these diseases with Pearl White, employing preventative measures and acting at the first sign of infection.
Bacterial Leaf Spot is a disease that causes dark, water-soaked spots on foliage. It spreads rapidly in high humidity and causes defoliation and reduced health. Use proper humidity levels to prevent spread.
Botrytis is a common fungal disease that causes brown spots on stems, leaves, and flowers. Remove and destroy affected plants, maintain appropriate humidity levels, and apply fungicides with boscalid, fenhexamid, or iprodione to control the spread.
Powdery Mildew is a fungal disease that thrives in humid conditions, appearing as a white or gray coating on foliage and flowers. Provide good airflow in your greenhouse. We recommend using horizontal airflow fans to help control humidity levels. You may also use a dehumidifier or manual venting. Remove and destroy infected plants and apply fungicides as needed or preventatively. Look for the active ingredients myclobutanil, trifloxystrobin, or potassium bicarbonate to combat Powdery Mildew threatening your seedling plugs.
Root Rot is a disease caused by soil-borne fungi that destroys plant roots, causing the plant to wilt and die. Overwatering or growing seedling plugs in poorly drained soil can make its effects devastating for your crops. Allow soil to dry between waterings, provide adequate airflow and spacing, and grow seedling plugs in well-draining soil.
Planting Pearl White Liners
We recommend planting one seedling plug per 4-inch or three per 10-inch container. Use well-draining soil and center or evenly space the ellepots in the containers.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
