Answer: Part of the problem may be the season -- once stocks are depleted many growers will not ship until the warm weather returns. This plant is also somewhat slow to reproduce and grow into a large size and with heating costs having gone up, it makes the crop more expensive and less profitable to produce, so fewer growers may offer it. Too, styles come and go with some plants being more popular than others. You might check with your retailers and see if they expect to have some come in soon, or you might try propagating some on your own, depending how soon you need these. I did locate a catalog retail source, Glasshouseworks, in case you are still considering that option. Their plants tend to be quite small starts, in my experience, not full grown specimens.
Best of luck with your grape ivies!
