Techno® Heat Upright Light Blue Lobelia

Techno® Heat Upright Light Blue is an annual Lobelia erinus with light blue, violet-toned flowers and an upright growth habit. The registered variety profile records this exact selection and its distinctive pale corolla markings; the Techno upright series is bred for early flowering and color through warm weather. [Canadian Plant Breeders’ Rights profile](https://active.inspection.gc.ca/english/plaveg/pbrpov/cropreport/lob/app00008579e.shtml) ## Flowers and placement The light blue flowers bring a cool accent to containers, window boxes, and the front of a sunny or partly shaded border. Lobelia erinus is commonly grown as a seasonal annual and performs best when the root zone stays moist but well drained. [Illinois Extension](https://extension.illinois.edu/flowers/lobelia) recommends full sun or partial shade and notes that Lobelia may pause flowering in hot weather. An upright selection is useful where a tidy vertical shape is preferred over a trailing spill. ## Growing conditions Give plants good light and regular moisture, particularly in pots. Avoid leaving roots in standing water; a free-draining growing mix supports healthy growth. ## Maintenance Check container moisture frequently during warm spells. Remove faded stems or lightly trim uneven growth to maintain a clean outline, then continue watering so the plant can produce fresh foliage and flowers.
