|I have collected seeds from my Ligularias, both L. przewalskii 'The Rocket' and L. dentas 'Desdemona' but I can not get them to germinate, and I have not found any seedlings around the plants either during the year, or the following spring.
Do you have any hints on how to get them to germinate, or is the seed rarely viable. (They seem to get polinated just fine, and ripen fuzzy seed heads.)
|Ligularia seeds are erratic in germination and can take 14-42 days to sprout when kept at 55F - 65F degrees. Sow the seeds on the surface of moistened seed starting mix and barely press them in with your hand. Cover the pots or trays with plastic wrap to help hold in the moisture and keep the trays in a cool room. The soil must be kept moist, but not soggy wet. The seeds need light to germinate (don't bury the seeds). Viable seeds should sprout 2-6 weeks after sowing.|
