Coleus 'Rainbow'

Rainbow likes a position of partial sun and remember to water often. Keep in mind when planting that Rainbow is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside.

Try to aim for a seed spacing of at least 11.7 inches (30.0 cm) and sow at a depth of around 0.0 inches (0.01 cm). Soil temperature should be kept higher than 65°C / 149°F to ensure good germination.

By our calculations, you should look at sowing Rainbow about 56 days before your last frost date.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Rainbow is a tender plant.
