Techno® Heat Electric Blue Lobelia

Techno® Electric Blue is an annual Lobelia erinus with vivid blue flowers and a low, mounding, spreading habit. Syngenta lists it at 6–10 inches high and 18–22 inches wide, flowering from early spring through summer in partial or full sun. [Syngenta Flowers](https://www.syngentaflowers.com/ams/product/flower/70003827) ## Flowers and placement The densely branched plants fill baskets and mixed containers quickly, while their broad spread works along a bed edge. The breeder describes this selection as heat tolerant and pollinator friendly, so it can keep color as temperatures rise and offer flowers for visiting insects. Lobelia erinus generally flowers most freely in cooler weather and prefers moist, well-drained soil; [Illinois Extension](https://extension.illinois.edu/flowers/lobelia) notes that heat can pause flowering. ## Growing conditions Choose a bright site with partial shade available during hot afternoons. In a basket or pot, use a free-draining mix and check moisture often because exposed containers dry quickly. ## Maintenance Keep the root zone evenly moist, especially in containers. Trim tired stems to keep the plant neat, and water consistently during warm spells. A well-drained container and regular watering help this annual continue flowering through the season.
