Tulip 'Leen van der Mark'

Leen van der Mark 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).

Aim to sow 3.9 inches (10.0 cm) deep and try to ensure a gap of at least 3.9 inches (10.0 cm).

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