Mullein 'Arctic Summer'

Try to plant in a location that enjoys full sun and remember to water very sparingly. Keep in mind when planting that Arctic Summer 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).

sow early to mid spring for bloom the following summer.

Best germination temperature 68 deg F.

Time from sowing to germination: 3 – 14 days.

Aim to sow 0.04 inches (0.1 cm) deep and try to ensure a gap of at least 3.25 feet (1.00 metres). Soil temperature should be kept higher than 15°C / 59°F to ensure good germination.

By our calculations, you should look at sowing Arctic Summer about 49 days before your last frost date.

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