Propagating California Lilac (Ceanothus) from Cuttings and Seeds

How to Propagate California Lilac

California lilac (Ceanothus) can be started from seed or cuttings. Seeds require a 12-hour soak in warm water, then 90 days of cold stratification in a damp paper towel inside a sealed bag in the refrigerator. After stratification, sow in moist potting mix.

For cuttings, take semi-ripe stems in late summer. A detailed guide is available at Gardenaction.

Quick Tips

• Seed: soak → stratify 90 days → sow.
• Cuttings: use semi-ripe wood, rooting hormone, and a humid environment.
• Both methods require patience; cuttings often root faster.
