I don't think so Larry. I'm more in a west Texas situation where I'm located, as opposed to an east Texas location where Dave the man is located. I only have to travel a few miles east to see the difference visually. On the other hand I only have to travel about 25 miles west until I run out of landscapes that grow trees. At the rate they've been dying in my area, I'm afraid the edge of that tree growing line is receding eastward. That is dictated by rainfall, I think. To grow a lot of daylilies successfully here would require a source for a lot of supplemental water. Big hybridizers tend to grow seedlings in large quantities, so the lack of natural rainfall and expense of growing daylilies in those quantities means they would likely locate somewhere else. Then there is the wind. It's also not a friend to daylilies and it's nearly always present here. I can go east and south and leave the wind behind, but it only gets worse going west or north. Some of those coming from Oklahoma might come from areas more similar, but the winters would be colder and, again eastern Oklahoma is much different than central or western Oklahoma. Maybe the harsh growing conditions are the reason, but as a general rule, there is limited interest in gardening in my area. Vegetable gardening some. There used to be quite a few fruit orchards, but no longer. Too frustrating, I think.
