Clematis-flowered Columbine 'Bordeaux Barlow'

Keep in mind when planting that Bordeaux Barlow is thought of as hardy, 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).

Soil temperature should be kept higher than 18°C / 64°F to ensure good germination.

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