Latin Name: Lobelia erinus ‘Hot’ 

The Lobelia ‘Hot’ is a compact, eye-catching annual prized for its intense, heat-tolerant blooms and mounded habit. Growing 6–8 inches (15–20 cm) tall with a spread of 10–12 inches (25–30 cm), it’s ideal for containers, borders, and edging.

This improved cultivar produces masses of 0.5-inch (1 cm) vibrant red or deep pink flowers with small white eyes, blooming spring to frost in cooler climates (may pause in extreme heat). Unlike traditional lobelias, it maintains color in warmer temperatures and self-cleans without deadheading.

Thrives in full sun to partial shade and moist, well-draining soil. Drought-sensitive—keep evenly watered for continuous blooms. Attracts hummingbirds while resisting deer and rabbits.

Perfect for high-impact color, pair with white alyssum, blue ageratum, or silver dusty miller.
