Snake's head fritillary 'Mars'

Keep in mind when planting that Mars is thought of as half hardy, so it will need cloching or fleece protection when the temperature dips.

Look to ensure a distance 1.95 inches (5.0 cm) between seeds when sowing - bury at a depth of at least 1.95 inches (5.0 cm) deep.

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