Campanula makes a nice addition to a cut flower production in that it offers a bountiful crop in spring to early summer, often in the gap between early spring crops and summer annuals. Stems are sturdy and add structure, bulk, and visual interest to bouquets. Seed has been coated with conventional pellet for ease of sowing. Certified-organic growers please check suitability with your certifier.
Bright, clean, white bells. The Champion Series is bred for upright-facing blooms and uniform plants. Plants will produce flowers in the first year of production, if started early enough in the season.
NOTE: Plants should be started in fall, winter, or early spring. Daylength sensitive plants require short days during seedling development to ensure sufficient stem length and vegetative growth before flowering under long days.
• Fall-sown plants overwintered well in our unheated Zone 5 tunnel trials, blooming in early June on very tall, vigorous plants. • Winter-sown plants flowered in mid-June through early July on shorter plants in our spring tunnel trials.
Also known as bellflower or Canterbury bells. Ht. 30–40". Avg. 28,100 seeds/oz. Packet: 50 seeds.
DAYS TO GERMINATION: 7-14 days at 65-68°F (18-20°C)
SOWING: Transplant (recommended) - Sow into 128-cell plug flats or preferred seedling container, 6-8 weeks before planting out. Light is required for germination but applying a fine layer of vermiculite or growing media on top of the seed will help to maintain the moisture levels needed for germination and dissolve the pellet coating. Bottom water or mist lightly to avoid displacing seeds and soil. Direct seeding is not recommended. NOTE: Plants should be started in fall, winter, or early spring.

LIGHT PREFERENCE: Sun. Tolerates part shade.
PLANT HEIGHT: 30-40".
PLANT SPACING:For single-stem cuts, 4-6". For multi-stem / well-branched plants, 10-12". Support recommended. Note: Single-stem production finishes more quickly and is recommended for greenhouse production. Multi-stem production may be more suitable for outdoor production, where growing real-estate is less precious. Expect yields of 8-10 stems per plant.
HARVEST:Fresh Cut: Harvest when 2-3 lower buds on a stem are open. Keep upright position to avoid stem bending.
SOIL REQUIREMENTS:Full sun to partial shade; well-drained soil high in organic matter. 5.8-6.2 pH is ideal.

Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.
120 - 150 Days
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits. Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
Use for Cut Flowers and Bouquets
Variety good for fresh cut-flower displays.
Variety that we have found, based on our trials, to be the best performers in a climate-controlled greenhouse environment.
