These are  Hoya  Carnosa plants that are rooted in water bottles, it is recommended that you transplant them upon arrival into a 4" pot then as they grow up size them to a 6" the mature ones you see in my last two pictures are in 8" pots. They prefer to be root bound.

One of the first seven pictures are representative of what you will receive ( these are representative photos ), the pictures of the larger plant & beautiful Porcelain Flower blooms are from my mature plants.

Plants will have at  3-4 leaves on them.
