Technical specifications and varietal innovation

The improved variety of the Rainbow Coleus results from rigorous selection aimed at intensifying chromatic contrasts while strengthening the plant's robustness. The foliage features a unique velvety texture thanks to fine hair that accentuates the colored reflections under different lighting conditions.

This annual plant develops a compact root system perfectly adapted to container growing. Its moderate growth allows easy control of shape and volume, while its tolerance to partial shade considerably expands its planting possibilities.

Vilmorin seeds benefit from an optimized germination rate and genetic selection ensuring color uniformity in your planting. French production ensures perfect adaptation to local climatic conditions.

Sowing, planting and care

Sowing Coleus is ideally carried out from March to May, either indoors from February-March at 18-20°C, or directly in place after the last frosts. The fine seeds require surface sowing on quality compost, simply pressed without covering to encourage light-sensitive germination.

The growing medium should be light, well-drained and enriched with organic matter. A slightly acidic to neutral pH (6.0 to 7.0) promotes optimal development. Regular but moderate watering maintains the necessary freshness without creating excess humidity.

Pinching the stems is an essential technique to encourage branching and obtain a compact, bushy habit. This operation, carried out regularly on terminal shoots, stimulates the emission of new branches and densifies the decorative foliage.

Expert tips and plant combinations

To maximize the visual impact of the Rainbow Coleus, combine it with silver-leaved plants such as cinerarias or helichrysums that enhance its purple colors. White or pale pink begonias also create refined chromatic harmonies.

In planters, combine the Coleus with trailing plants such as lobelias or bacopa to create dynamic layered compositions. Adding liquid fertilizer for green plants every two weeks during the growing period intensifies the foliage coloring.

Professional tip: avoid direct exposure to harsh midday sun which can alter the delicate colors. Prefer a bright location with morning or late afternoon sun. Indoors, place the plant near an east- or west-facing window for optimal lighting.

To extend the season, bring potted plants indoors before the first frosts and keep them in a cool, bright room during winter.
