Cotinus coggygria 'Purpureus': Cotinus coggygria, also known as the smoke tree, is a deciduous shrub native to southern Europe and Asia. The seeds should be sown in a well-draining soil mix and kept moist. They require cold stratification to germinate, which can be achieved by placing the seeds in a plastic bag with moist soil and refrigerating them for 4-6 weeks. After stratification, the seeds should be sown on the surface of the soil mix and kept moist. The ideal temperature range for germination is 18-24�C (64-75�F). Germination can take anywhere from 2 to 4 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.
