Can Old Rose Seeds Still Germinate? Testing Viability After Long-Term Storage

Rose seeds prefer cool, dry storage (like a refrigerator). Seeds kept warm and dry for 15 years have reduced viability, but it's worth a try. The worst outcome? They don't sprout. Some seeds remain viable for decades.

How to test: After the last frost, sow them outdoors in a prepared seedbed. Keep moist. If they germinate, you've got a genetic lottery ticket—each seedling will be a unique new variety. If not, you've lost only a little time and space.
