Border plantings: Lobelia erinus

Lobelia erinus L.

Border plantings of Lobelia erinus rely on the use of compact and dwarf forms, 8–20 cm in height, which create the effect of a dense floral ribbon. This type of planting requires strict drainage control and regular pruning to maintain aesthetic appeal and promote repeat blooming.

In the reference 5 varieties crop Edging lobelia, where this is mentioned in the description.

Specialized garden forms of Lobelia erinus with a spherical or compact habit are used to create borders, as they are capable of maintaining a distinct planting line, unlike trailing varieties. High planting density ensures continuous coverage, where numerous small flowers completely mask the vegetative mass, creating a uniform ribbon of color with no discernible texture of individual inflorescences.

High planting density in borders requires particular attention to drainage to prevent root rots, to which the plant is sensitive during water stagnation. To maintain a continuous decorative effect throughout the season, regular pruning of spent shoots is necessary, which triggers a secondary wave of flowering. Under Russian climatic conditions, such borders are formed exclusively via the transplant method due to the crop's annual growth cycle.
