| Hi all,
I have a potentially silly question but I need a serious answer, LOL! I have tried searching for the answer but I could not find anything satisfactory. Do different species of Rudbeckia pollinate each other and form interspecific hybrids in subsequent generations? I would like to grow both R. triloba and R. hirta in my garden next year, but not if they will cross pollinate. I understand that different strains of R. hirta can cross pollinate, but just not sure if R. hirta will form hybrids with other species as well. Thank you in advance for any help,

| I've never heard of it, but that doesn't mean that it's not possible or doesn't happen. FWIW, I recently saw some pictures of what are supposedly Echinacea x Rudbeckia hybrids. |

| I have seen them too. Mixed messages concerning hardiness and whether the plants are really perenial. No information whether the seeds germinated 'normally' or developed in a laboratory. They are marketed as Rudbeckias: Berlin, Dublin, Peking. |

| wieslaw, I've seen those too and they look like just regular R. hirta type strains, at least to me. The Echinacea x Rudbeckia plants that I saw were very different. |
