Rocketliners are sized, shaped and rooted throughout the pot with strong and responsive roots. Gardeners can expect a healthy finished plant within a single growing season. They have greater fresh root mass and vertical root training which promotes faster finishing times. While it can often take up to 3-years for a shrub or vine to become fully established growing from bareroot, Rocketliners may only take 12-months, saving you up to 2 seasons of waiting time. Rocketliners are for gardeners that have busy lives, little time to waste and want to start out with the best planting stock. Clematis terniflora, also known as Sweet Autumn Clematis, is a semi-evergreen in milder climates with profuse, fragrant white flowers. Blooms throughout the fall, followed by feathery silver seed heads. Vigorous grower that blooms on current season's growth.
