Germinating Alstroemeria Seeds
Mark Bridgen

Germinating Alstroemeria seeds is not always easy. If they are fresh seed, they will germinate faster. If not, try this:

Pour boiling water over the seeds. This will help to crack the hard seed coat. Leave the seeds in the water until it cools, and usually overnight. Then, sow the seeds in typical warm conditions anywhere from 72-80°F for 4 weeks.

If they have not germinated, put the moist seeds in the refrigerator for 4 weeks. Keep them moist, but not wet.

Remove the seeds and return them to the warm conditions. Remove seedlings as they germinate.

You may have problems with seed rot during this process. Also, due to the genetic variability, some seeds may germinate fast and some may be more recalcitrant. Be patient. As long as the seeds are firm, and not rotten, there is a chance that they will germinate.
