Answer: You can plant the seeds within the fruits of Viburnums. They need to go through a double dormancy; 60-90 days at 68-86 degrees, then 30-60 days at 41 degrees or less. So, collect the seeds at the end of the summer, remove the pulp from around them and plant them in containers of potting soil, just barely covering them with potting soil. Leave the containers outdoors so the seeds experience cold temperatures. The seeds will germinate the following fall. If not, they'll germinate the following spring.
