Hello if you order for feb they will send scion wood. I got some from them last year.

The folks at corvallis are great. Not sure about invitro. We ordered many varieties from them two years back. The scion was good Their selection is amazing.
If your in California try the California rare fruit growers association they host scion exchanges each winter. They have individual chapters up and down the state. Very cool that you put the sunset zone too. I like their method of zoning. USDA is fine too
Happy growing

They are very generous with their scion. They sent more sticks of scion than I could use. I did get pear blister mite which I didn't have before, but I can't say if it came from them or another company I ordered from.
