Throughout the south and southwest, clematis and silverlace vines are popular perennial vines that provide returning color throughout the summer. Vines like silverlace have a reputation for being easy to grow, and will grow in coastal areas where salt spray will kill many other plants. Clematis is often considered more difficult to grow, but if you provide the leaves with full sun and shade the roots, clematis thrive. Both clematis and silver lace are typically sold by rhizomes that you can plant in the ground, but you can propagate the plants from seed as well.
Collect seed heads from clematis or silverlace vine in fall when the seeds form. Be careful to keep each seed type separate.
Mix each set of seeds with a cup of damp peat moss. Place the seeds and peat moss into separate glass jars and label them with a marker to tell them apart. Place the jars into the refrigerator where temperatures are set below 40 degrees. This process simulates the freezing/thawing of seeds in the ground in winter and will help the seeds to germinate in spring.
Fill two separate trays with peat moss. Make planting holes in the center of each cell of the planting tray to plant the seeds. Each planting hole should be about twice the width of the seed at its widest point.
Drop a seed into each planting hole and cover with peat moss. Mist the surface to keep the peat moss as damp as a wrung-out sponge. Cover each tray with plastic and label the trays to differentiate between the clematis and silverlace. Place each tray under a plant grow light.
Remove the plastic from the cover of each tray once the seedlings have sprouted. Transplant the seedlings into larger containers as they outgrow the cells of the seedling trays by filling 6-inch containers with potting soil and opening a planting hole in the center of each container. Place the seedling’s root ball into the center of each container and cover with soil.
Move each container outdoors gradually to harden off the sprouts inside each container. When the seedlings have hardened off, transplant them into the ground.
