Question about Hosta 'Oshima Silk' parentage

Postby waldo » Jun 25, 2017 10:04 am

Chris, I am sorry for the delay but when talking about "Oshima Silk" you said "long story about that one, but the plant tissue cultured and sold as Oshima Silk wasn't the same plant that was registered" I would be interested in any details of that long story that may be pertinent to my using this hosta in my breeding progam. I try to gather as much information and background on plants that I start with. One of the reasons that I find it disappointing when I see unknown or H. "X" x unknown listed for parentage of newly registered hostas.

Hi Waldo,

Hosta 'Oshima Silk' is registered as a white edged seedling of Hosta pycnophylla by Mark Zilis/Q & Z Nursery that Mark acquired in Japan. The picture Mark used for marketing in the catalog and on the plant tags is this one:

oshima-silk-zilis.jpg


Clearly that is completely different from the plant that was actually introduced in tissue culture, which is this one:

Hosta-Oshima-Silk-flowers.jpg


For a while Mark insisted that the plant in tissue culture was the same as the first one pictured. I kept bugging them about it, wanting to know what in the world we were actually growing, and eventually Mark relented that the plant known as Oshima Silk out of tissue culture is not the same as what was registered. It was brought back from Japan and they don't have any idea what this is, or how it originated.

So unfortunately what is now sold as Hosta 'Oshima Silk' has absolutely no relationship to the plant that was registered as such. It clearly is not related to Hosta pycnophylla and the registration should be corrected to simply be unknown parentage.

Wish I could help more, but that's a bit more of the story.

Chris

Wow. I didn't know this but do like "our" 'Oshima Silk'. This is a worse mess than Geisha/Ani Machi.

Thanks Chris, that is very helpful. It doesn't mean that I won't use it in my breeding plan, but it will help me to make correct decisions on what direction I go.

Here are some flower photos from yesterday.
