Musk mallow 'Alba'

Keep in mind when planting that Alba 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 14°C / 57°F to ensure good germination.

As Alba is hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
