Cariboo™ Forte Blue Campanula

[Cariboo™ Forte Blue](https://online.flippingbook.com/view/540220313/20/) is a compact Campanula bellflower with deep blue flowers and an upright habit. Syngenta introduced it for spring and summer color in containers, including larger quart and gallon pots. The series does not require vernalization. ## Form and use The breeder catalog lists plants about 14–18 inches tall and 8–12 inches wide, with a strong upright form. Its blue flowers suit patio pots and mixed container plantings. The catalog lists hardiness in USDA zones 5–9 and allows part sun to full sun. Syngenta’s [Cariboo product page](https://www.syngentaflowers.com/ams/product/flower/70088357) describes Big Blue Star as an upgrade to Forte Blue, with increased vigor for filling larger containers. ## Growing conditions Place in a bright site with full sun or partial sun. The available Cariboo source emphasizes container production but does not specify an exact soil or irrigation schedule. Use a well-drained potting medium and adjust watering to keep the root ball from drying out. ## Maintenance Remove spent flowers and damaged stems to keep containers neat. Monitor moisture more frequently in small pots and during warm weather. Follow the supplier’s current production guidance when starting from cuttings or finished plants.
