Starting Roses from Seed
Expand your garden and have a little fun by growing a few plants from the seeds of your favorite rose.
Collect the rose hips, those berry-like fruit on your roses, as soon as they are fully colored. Cut open the rose hip exposing the seeds. Soak the seeds 12 to 24 hours, drain and mix with equal parts of moistened sphagnum moss and vermiculite in a plastic bag. Seal the bag and place in the refrigerator for at least three months.
You can begin planting the seeds anytime after the chilling period is complete. Plant seeds in a container filled with a mixture of sphagnum moss and vermiculite. Keep the mixture warm and moist. Move to a sunny window or under artificial lights as soon as the seeds sprout. Then transplant seedlings, if needed, after they form two sets of true leaves.
Just remember seedlings may not look like the original plant.
A bit more information: You can also start new roses from cuttings. Take a 6 to 8 inch cutting from a healthy stem. Remove any flowers and buds. Dip in a rooting hormone and plant in a well-drained potting mix. You’ll have roots in about 3 weeks. Keep in mind you cannot propagate patented roses. These rights belong to the breeders that introduced the plant.
