TreeHelp Syringa vulgaris Alba Lilac Seeds

Yes, these seeds require cold stratification to break dormancy and ensure successful germination. You can achieve this by planting them outdoors in the fall for natural winter chilling or by simulating the process indoors before sowing.

Syringa vulgaris 'Alba' is a substantial shrub that can reach a mature height of approximately 240 inches, or 20 feet. Be sure to select a planting site with enough vertical space to accommodate this size.

You have flexibility with these seeds. They can be started indoors if you provide the necessary cold stratification period, or they can be sown directly into the garden during the fall to mimic natural spring emergence.

Each packet contains 40 hand-sorted seeds. We hand-sort them to ensure you receive high-quality, viable seeds for your project.

For the best results, plant the seeds at a depth of 0.25 inches. Planting them too deep can prevent the seedlings from successfully breaking the surface.

When stored properly in a cool, dry place, these seeds remain viable for up to one year. This allows you to plan your planting schedule around your gardening timeline.
