Clematis 'Double Cross'

Try to plant in a location that enjoys full sun and remember to water often. Keep in mind when planting that Double Cross 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).

Look to ensure a distance 1.48 feet (45.7 cm) between Double Cross seeds when sowing to make sure your seedlings have enough space.

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