How to Grow Clematis From Seeds

Clematis produces woolly seed heads after its flowers have gone to seed. These seed heads will open up later in the fall, revealing brown seeds. Once you notice the seeds, keep a close eye on them, gathering them as they mature and drop to the ground.

Note: Clematis seeds are short-lived and cannot survive more than a few months. As such, sow the seeds as quickly as possible. Alternatively, you can store them in the refrigerator for a couple of weeks.

2. Prepare the Seeds

Soaking the seeds in warm water for 12 to 24 hours before planting will soften their tough coats. This will speed up germination.

3. Plant Them in a Pot or Container

The best time to sow the seeds is in early spring. Use a container with drainage holes and standard potting soil. Plant the seeds about 1 inch (2.5 cm) deep and 1 inch (2.5 cm) apart.

4. Place in the Dark

It's important to keep newly planted clematis seeds dark. You can tape aluminum foil over the pot's drainage holes to ensure no light can seep in.

5. Keep the Pot Warm

Clematis seeds need to be kept warm. To assist in germination, you can place a warm, damp washcloth over the pot and place the pot in a warm spot.

6. Mist Regularly

The soil should be kept consistently moist, but not soggy. A spray bottle can come in handy for misting the soil.

7. Wait for Germination

With adequate care, germination should occur in about 4 weeks. However, some clematis seeds may take longer. Do not dispose of the pot if germination does not occur immediately.

8. Transplant Seedlings

Clematis will produce delicate seedlings. If they have become tightly clumped, you can carefully separate them once two pairs of leaves appear on each seedling.

If they still have room to grow in their container, transplant the seedlings into larger pots come the fall. Alternatively, you can wait to transplant them after they have had a couple of years of growth in the container.

9. Move Seedlings to Desired Spot

Once clematis seedlings have reached several feet tall, they are large enough to be transplanted to their permanent spot. They will prefer well-draining soil and a spot with access to morning sunlight.
