About Techno® Blue Lobelia

Techno® Blue is a mounding, spreading lobelia with blue flowers and a dense, fast-filling habit. Syngenta lists it for early spring through summer, in part or full sun, and notes its heat tolerance and pollinator appeal. ## Plant Profile The [Techno® Blue plant page](https://www.syngentaflowers.com/ams/product/flower/70003825) identifies code 70003825 and gives a garden size of 6–10 inches tall by 18–22 inches wide. Its broad, low habit works in hanging baskets and mixed containers, where it can spill over the edge while filling in with color. The listed hardiness value is 11a; this tender bedding lobelia is also commonly grown as an annual in cooler climates. ## Growing Conditions The species guidance from [NC State Extension](https://plants.ces.ncsu.edu/plants/lobelia-erinus/) recommends organically rich, moist, well-drained soil and regular watering. Lobelia erinus tolerates full sun to part shade, while Syngenta lists both part sun and full sun for Techno® Blue. In hot weather, consistent moisture and some afternoon shade can help maintain the display. ## Maintenance Water regularly and do not allow the soil to dry completely. Use a well-drained potting mix in containers and ensure hanging baskets do not dry out between checks. Remove tired stems to refresh the planting as needed.
