If you're not able to take cuttings, it's possible to grow kudzu from seed. I've seen sites that say they won't germinate without abrasion, freezing, treatment with acid, etc. That's ridiculous. Growing kudzu from seed is actually quite straightforward, just error-prone. Here's the process I used.
Pick seed pods that are dry and are in the process of splitting open. Kudzu has about 1-3 seeds per pod, each about 1/2 the size of a grain of rice.
Save seeds that are fat and shiny looking, a bit like tiny pinto beans, not dry and shriveled. Kudzu seeds are very susceptible to parasites of various kinds. I suspect this has evolved because the plant spreads so well by vegetative propagation.
Use pliers, forceps or some other tool to rupture the seed coat of each seed. The idea is to create a split that allows the growing seedling to break apart the seed coat.
Place the seeds into the pores of a damp sponge, and put the sponge in enough water to keep it moist. Standard germinating procedure. The endosperm will swell up and break open the seed coat as the seed germinates. About 70% of the seeds should germinate.
After the seedling grows to a length of about .5 cm, plant it in some potting soil in a warm location with full sun. The soil must stay moist or the seedling will dry up.
This will get you past germination, but the plants need a lot of attention until they're ready to make it on their own. An LED grow light and regulated heater might help, but I don't have time to determine the best growing conditions. If I need a lot of tissue, I'll just go to Virginia.
