Vinca won't grow roots #818100

My son is trying to propagate new vinca vines via cuttings. Putting them in 'dirt' didn't work very well, so he tried water. The cuttings stay healthy, but instead of developing roots, they develop new leaves - under water. This is from a potted vinca.

Expert Response
You should be able to root vinca cuttings in water fairly easily. Cut a flower-less stem off the vinca at a node, remove all lower leaves so that none are present in the water, and place the stem in the water-filled container. New roots should be visible in a few days to a week.

That's what he did. Roots didn't develop, just new leaves.
I'm attaching a couple of links with specific information about rooting vinca plants. While not authored by educational institutions, the advice should be helpful. If he follows these guidelines carefully, your son may be successful in rooting his vinca.
