Germination of

Paulownia tomentosa

Royal Empress Tree, Empress Tree, Foxglove Tree

Paulownia tomentosa

Paulownia tomentosa: Paulownia tomentosa, or Empress Tree, seeds can be germinated by stratification. Mix the seeds with moistened vermiculite or peat moss, and place the mixture in a sealed plastic bag. Refrigerate the bag for 30 to 60 days. After stratification, sow the seeds in well-draining soil, about 1/4 inch deep. Keep the soil consistently moist and provide a temperature of around 70-75°F (21-24°C). Germination may take several weeks.

Some of plants may have very have specific germination requirements that may not be covered in these general instructions. 

Many seeds require pre-treatment before sowing which we try to list here when we can, but this information may not be present here.  Germination times and germination temperatures are to be a guide only.  Many factors can DRASTICALLY affect this.


It's always a good idea to research the specific germination requirements from multiple sources for each plant before attempting to grow them from seed.
