The new Campanella Campanula series from PanAmerican Seed fits very easily into the latest home trend of placing living color in the spaces we spend the most time — indoors! Campanella has large, bell-shaped blooms that fill pots better with more flowers. The bells are charming and easy to care for, making it great for a plant novice. Campanella is also vigorous, meaning it is suitable for larger pots for bigger impact. Here are a few growing guidelines to produce a quality crop of this on-trend flower.

Production

Plug crop time: 6-7 weeks

Transplant to finish: 7-10 weeks. We recommend one seed per cell in a 288-plug tray. No need to cover the seed; germination takes place in 10-14 days. Maintain a level 4-5 (wet to saturated) moisture during stage 1 at a temperature of 65-68^° F (18-20^° C). Apply fertilizer at a rate of less than 100 ppm N.

During stages 2 and 3, provide medium moisture at level 3-4 and maintain the stage 1 temperature. Increase fertilizer from 100 to 175 ppm N, 0.7 to 1.2 EC. In stage 4, lower temperatures slightly to 60-64^° F (16-18^° C). Moisture can be set at level 3 (medium) and maintain the same fertilizer rate from stage 3.

Critical to the culture of Campanella is the short-day treatment in the plug stage. Start short-day treatment of <11 hours daylength two weeks after sowing. This prevents flower initiation in the plug stage and results in the right plant habit for filling pots nicely after transplant.

After transplant, long days (>14 hours) are essential to initiate flowering. Set day temperatures at 62-64^° F (17-18° C), night temperatures at 58-60^° F (14-16^° C). If more vigorous plants are needed, two weeks of short-day treatment (less than 11 hours daylength) before long-day treatment (more than 14 hours daylength) will result in more vigorous plants.

Campanella is responsive to B-Nine/Alar 2,500 ppm or tank mix of B-Nine/Alar 2,500 ppm, as well as Cycocel 500 ppm. The recommended finished pot size is 5 in./13 cm and pinching is generally not needed. However, when using bigger pots, a soft pinch can result in fuller and bigger plants.

Growers can position these flowering plants as part of the indoor houseplant trend or as gift plant items (grab-and-go impulse items at retail). Consumers can enjoy them as part of their home’s décor, and gain all of the benefits that nurturing indoor flowering plants offer, like indoor air quality, stress relief and overall wellness.
