What are Rainbow Coleus Plants?
Rainbow coleus plants (Solenostemon scutellarioides) are herbaceous perennials that are native to Southeast Asia.
They belong to the mint family (Lamiaceae) and have brightly colored foliage that can range from green, yellow, pink, red, purple or orange.
The leaves of these plants come in different shapes such as heart-shaped or serrated; they have unique patterns like spots or stripes.
How to Plant Rainbow Coleus?
To grow rainbow coleus successfully, it is best to start them indoors about 8-10 weeks before the last frost date in your area.
This will give them plenty of time to grow before transplanting them outdoors after danger of frost has passed.
- Choose a well-draining soil mix that contains peat moss or perlite
- Sow the seeds into trays at least 4 inches apart
- Cover lightly with soil mix then water gently using a spray bottle
- Place trays in warm areas where they can receive indirect sunlight for at least six hours each day
- Maintain moist soil until germination which usually takes between 7-14 days
- When seedlings emerge remove coverings if any then move tray into direct sun exposure gradually increasing the duration from 30 minutes to two hours for the first week
- At 4 weeks old, transplant them into containers or flower beds positioned in well-draining soil mix and spaced at least one foot apart.
