A bit more detail, on the correct statements above: Fortuniana is more difficult to work with at all stages. First, rooting the cuttings. With Dr. Huey, you take leafless cuttings (think thick pencils) in the fall, poke them into the field soil, irrigate as necessary to keep the soil moist, and come back in the spring and you have plants. With Fortuniana, you have to use leafy cuttings (leafless cuttings give a poor rate of success), and they are coddled along in small pots, under an intermittent mist system. We also double-wound the base of each cutting, and dip it in fairly strong rooting hormone (Dip-N-Grow diluted 1:5 or 1:6) before sticking. Done that way, we get well over 95% rooting success.
Once rooted, Dr. Huey is easily budded by the shield-budding method (a.k.a. T-budding), where the bark is cut horizontally and vertically like a capital letter T, and the scion bud is slipped under the bark and then wrapped. Very quick, very easy, and takes just a few seconds for a good budder.
With Fortuniana, T-budding is virtually impossible -- the bark shreds into little rope-fiber-like shreds. Instead, you have to chip bud them, or better, cleft graft a leafy scion on top and put it back under the mist for another month. If you're good, you can approach 98% success, but it takes a good and experienced grafter to do that. T-budding takes far less time, care, and experience, to get good rates of graft success.
Next, time to grow the graftling out to sellable size -- Dr. Huey makes inherently thicker canes to start with, and makes a very vigorous plant right at first. Fortuniana is normally budded or grafted when the rootstock cane is much thinner. So it often gets off to a slower start. HOWEVER, once up and growing, the Fortuniana-rooted plant will, generally in the first season, pass the Huey-rooted plant, to become the larger, more vigorous bush.
Finally, while Fortuniana makes a very pest- and disease-resistant root system, it is a physically weak root system, so each plant has to be firmly staked, for its entire life, or it will fall over. Dr. Huey makes a much more sturdy, inherently upright plant, so the nursery doesn't have to worry so much about the time, labor, and $$$ of a staking operation.
