How long can Jimson weed seeds remain viable?

Jimson weed seeds can remain viable for an extended period, often up to a century under the right conditions. This longevity is attributed to the tough seed coat that protects the embryo from environmental factors that could impair germination, such as extreme temperatures and moisture levels. This remarkable viability allows Jimson weed, an invasive plant species, to spread efficiently and proliferate in various habitats over many years, making management of the plant particularly challenging for landowners and ecologists. The capacity for long-term dormancy in the soil is a significant factor in the plant's persistence and spread.
