You are welcome! It seems the boards have almost come to a stop. That's too bad. You can have fun crossing these with other sororias. Some see these as weeds but if you have a space for them, seeing them in mass is quite charming.

I'm not convinced that they are from one flower...I think that the flowers were probably very close...if they were from one flower they would have been fused somewhere on the tomato, and they are clearly 2 separate fruits. I think they just grew very, very close together!

I don't know about your specific species of Diphasiastrum, but in my neck of the woods, my experience in trying to move them from areas slated for building suggests that they are difficult to transplant, even when only getting moved short distances (several feet). This agrees with William Cullina (New England Wildflower Society and Coastal Maine Botanical Gardens) in his book Native Ferns, Mosses & Grasses where he says, "I hesitated about whether to include the clubmosses in this work, as they can be quite refractory in cultivation." He goes on to rate them as difficult to propagate from division (though he has had some success) and unsuccessful in his experience from spores. Elsewhere I found a comment that it could be 20 years from spores, so between the two, I imagine that it's not commercially feasible. I've also read some speculation from Cullina and others that they may need mycorrhizal fungi to grow well, though I don't think this is established as fact. I don't know if anyone has tried growing them from tissue culture. I did find one sales listing for a bog Lycopodium, L. appressum from the Meadowview Biological Research Station in VA.

Patty, that is an interesting question. Professor Roush (see his blog at http://kansasgardenmusings.blogspot.com/) brought up a related question after RRD decimated his Buck rose collection. Roush wondered if roses from different genetics, in his case the OGRs like the gallicas, were more resistant. I have never seen, knock on wood, RRD in my big patch of native roses, but I just found it in a plant of Rosa canina. I have a huge (20' by 25') plant of Rosa setigera next to the Rosa canina, so I will be watching...The R. setigera leaves are kind of fuzzy -- very different from both R. canina or the leaves of typical HTs. I will be curious to see what answers you get! Sunny
