Depending upon the age of the seeds, and the treatment the greenery received upon harvesting, you may very well be able to sprout the seeds. Eucalyptus seeds need a prechill treatment prior to germination, and bottom heat during germination. If you're successful, you can grow your Eucalyptus indoors during the winter and outdoors during the spring and summer months. The trees are native to Australia and grow outdoors in Southern California, so you won't be able to keep them outdoors during your winter months. Leave the seeds in their pods, mix them with moistened growing medium, seal in a plastic bag, and place in the refrigerator for 4 week. Then remove the seeds from their pods and place them on the surface of moistened seed starting mix in individual pots. Press them in with your fingers, but don't cover the seeds. Put plastic wrap over the pots to help them retain moisture then place the pots in a warm area such as on top of the refrigerator or on greenhouse propagating mats. If the seeds are viable, they should germinate in 14-90 days. Remove the plastic as the seedlings sprout and place the pots under a source of artificial light.
