Happy update! First, though, thank those who gave me source suggestions. I was lucky enough to find a local source, though--A year or two ago I spotted a Poncirus trifoliata in the gardens of a dedicated lavender grower in a small town near Gettysburg. I believe it was a Flying Dragon plant. In any case, it had fruited, and there were numerous small seedlings at its base. I was permitted to collect a few of the seedlings, in hopes of getting one to live in my own garden. I took them home, planted them in an outdoor pot, and eventually transplanted the largest (about two inches tall at that point) in a shady spot next to my West-facing driveway.That spot is shaded by a tall pine tree and was in the process of becoming a garden after I discovered the remains of a large pile of mushroom mulch had become rootbound and was therefore no longer usable for mulch. The Poncius was not to be seen at all last summer, although I did not have much time to seek it out due to a family emergency. Therefore, imagine my surprise when, a couple of days ago, I spotted my little Poncirus, now about five inches tall and bravely putting out some new little leaves, only a few feet from a small Nearly Wild rosebush! I can only guess that a rabbit or squirrel bit it off last summer, but that its reported bitter taste saved it from a total uprooting. I placed a rock next it to afford it a bit of protection and am anxiously awaiting further developments. :o) !

Joel, I can trade you Strawberry Cream rooted cutting for your Poncirus. Interested, plmk. Linda

As with most temperate climate shrubs grown in your climate, morning sun, with shade from noontime on, is ideal. But I'd imagine that planted under tall trees, with mid-day shade and morning + afternoon sun, would also work.

The company replied, and told me that if I researched Ryusens, the characteristics would all be the same = same cultivar even if not same clone. Unless they thought Joe Public wouldn't be able to tell the difference between the two anyway, and since information on 'Eric's Weeping' was scarce descriptions of the other would do. Yes: it's not unusual for wholesale growers to have "their own introductions" that look a lot like existing, familiar varieties with different naming. For instance I've had a grower representative in my area use the same phrasing to characterize a conifer that had their own naming on it as was used about the 'Eric's Weeping'. That is that it had the same features as another, widely sold kind. As with the response about the 'Eric's Weeping' it wasn't an explicit admission that they had put their own name on an established variety, but... I've also had a grower here explain an unfamiliar variety name for a flowering tree they were offering by saying that it consisted of propagations of unlabeled specimens that were already on the property when they bought it. That they had actually assumed that this existing planting was the same kind as a variety they knew in the old country. But had gone ahead and made up a new name for their own sales here in the US. The way they came right out with this story made me think such looseness with cultivar names was thought to be standard operating procedure in the industry. There certainly are cultivars that have acquired multiple synonyms over time, same as with various wild species plants.
