Rock cress 'Moerheim'

Moerheim is generally regarded as a hardy plant, so it can be safe to leave outdoors for the majority of winter (although if in doubt, using a row cover is often a good idea).

For optimal germination, soil temperature should be a minimum of 10°C / 50°F.

Moerheim is hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside.
