About Lobelia:

Lobelia is a plant genus that includes various types such as Cardinal Flower, Lobelia erinus, and Lobelia siphilitica. Each type of Lobelia has its own distinct characteristics and growth habits.

Lobelia has an annual or perennial life cycle, depending on the specific type. It typically blooms during the summer and fall, attracting bees, butterflies, and hummingbirds with its vibrant, showy flowers.

Characteristics:

Lobelia is known for being easy to grow and maintain. It is often used as an ornamental plant, thanks to its beautiful flowers and attractive foliage. Some types of Lobelia, like Lobelia erinus, have extended bloom time, providing a long-lasting display of color. While Lobelia is not typically edible, it is fragrant and adds a pleasant aroma to the garden.

Growing Conditions:

Lobelia thrives in moist, well-draining soil and prefers full sun to part shade exposure. It is important to keep the soil consistently moist, as Lobelia is not drought tolerant. The plant also benefits from regular deadheading to promote continuous blooming.

Plant Care Instructions

Light Requirement

Fertilizer

Lobelias can benefit from a balanced fertilizer such as a 10-10-10. For an organic option, you can use compost or an organic granular fertilizer specifically formulated for flowers.

Pruning

Regular deadheading of faded flowers will encourage continuous blooming. You can also trim back the plant by one-third in late summer to promote new growth for a second flush of blooms.

Lobelias are generally non-toxic to humans and pets. However, it’s always a good idea to keep them out of reach of curious children and pets.
