Two of my P. lusitanica are putting up flower stalks and I think my P. primuliflora is also. With that in mind I have a few questions.
1. are P. lusitanica and P. primuliflora self pollinating (if not, how to pollinate)
2. can they be crossed
3. if so, can someone post detailed instructions (preferably with pictures) on collecting and transferring the pollen for making P. lusitanica x P. primuliflora
