Lobelia can be either annual or perennial, depending on the specific variety. Annual lobelias typically bloom throughout the growing season and die off in winter, while perennial varieties can flower year after year if conditions are favorable. To ensure healthy blooms, provide the right care, including proper watering and sunlight. In colder climates, perennial types may require winter protection to survive and flower again in the following season.
The scientific or taxonomic name would be Lobelia erinus.

Depending on the variety of lobelia that you're growing -- there are about 90 varieties -- deadheading generally promotes a neater appearance, although it is not necessary. Lobelia that you're growing in containers, or in your garden will grow in most any light condition, but prefer moist soil. If you apply fertilizer every month or so, your plants will flower from mid-summer until the first frost.

Lobelia typically blooms from late spring to early fall, depending on the variety and growing conditions. While some species of Lobelia are perennial, others are annual or biennial. Perennial varieties, like Lobelia cardinalis, can return year after year, providing consistent summer blooms. To ensure continuous flowering, regular deadheading is recommended.
Lobelia monostachya was created in 1988.
