This week, I bought a Dwarf Mexican Petunia (Ruellia brittoniana )and took cuttings of the dense plant today. Regular ruellia roots like crazy - put some cuttings in a bucket and a week later you'll have thriving plants with masses of tangled roots. These plants, which typically get to about 3 to 5 feet tall, have about an inch between leaf nodes. Root buds come out from in between these nodes. As you see below, the nodes on the dwarf are much closer together. I like this plant, and I am hoping to get a lot of babies from it, but I'm not sure how it will take to rooting. Here is what I did, and what I do for almost all of my soft root cuttings:
Anyway, here is what do. How do you like to propagate plants?
