superba bellflower seeds for planting

Grow Bellflower Superba from fresh Campanula glomerata flower seeds. Bellflower Superba will produce beautiful, deep violet colored blooms that span 1 to 2 inches wide. Each plant reaches a mature height of 16 to 20 inches tall and spreads 8 to 12 inches wide. Bellflower Superba is grown as a perennial flowering plant, meaning it will establish a deep root system. The plants will wilt during the frost, later returning the following year.

Bellflower Superba is known to attract an array of beneficial insects to the garden. These include many various butterflies & caterpillars, as well as bumblebees, ladybugs and hummingbirds as well. It can be used as a cut flower in many bouquets and floral arrangements and is also popularly used as a groundcover plant because of its short growth habit.

Plant Bellflower Superba out in the garden when the weather is warm. Grow them in borders, along fences, walkways & driveways, in containers or flower beds, or in an area that needs a splash of color. These plants need little care when established and are an excellent choice for any novice gardener.

Sowing The Seed

Although it's easier to establish Bellflower Superba in peat pots, we recommend choosing a calm day to sow these seeds directly outdoors. Choose a spot that you want to cover, removing all unwanted plant life from the sowing area. Scatter the tiny seeds directly to the surface of the soil, allowing them to receive direct sunlight. Do not cover the seeds as they require light to properly germinate.

Growing Conditions

Place your Bellflower Superba seeds in an area that receives full sunlight in cooler climates and partial shade in warmer climates. Keep temperatures at around 65F to 75F and provide them with a sandy, chalky loam. To increase drainage, we recommend adding a light compost to areas containing hard, compact soil. Water daily with a mist setting so that the seeds are not disturbed when watered.

Germination & Growth

Your seeds will begin to germinate within 7 to 14 days after sowing. The plants will reach a mature height of around 16 to 20 inches tall and 8 to 12 inches wide. The plants can be spaced about 8 to 12 inches apart from one another. Bellflower Superba produces mounds of attractive, deep violet colored flowers in the form of a groundcover.
