Tulip 'Curly Sue'

Curly Sue 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).

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