TattooGardener Clematis Jackmanii

Cold stratification is a process that mimics winter conditions to break the seed's dormancy. You will need to keep the seeds in a cold environment, such as a refrigerator, for several weeks before planting to ensure they germinate successfully.

Plant the seeds at a depth of 0.635 cm. It is important to be precise with this depth to ensure the seedlings have enough energy to break through the soil surface.

Clematis Jackmanii is hardy in zones 4 through 8. If you live within these regions, the plant is well-suited to survive the winter and return each year as a perennial.

This is a vigorous climber that reaches a mature height of 120 inches. Because it grows vertically, it is excellent for trellises or walls, but ensure you have enough vertical clearance to accommodate its full growth.

This variety thrives in full sun to part shade. For the best bloom production, aim for a spot that receives at least six hours of sunlight, though it will tolerate some afternoon shade in hotter climates.
