Juniper Types: Mounding or Running

I have two junipers I got as nursery stock a couple of years ago. I was wondering if they fell within the running or mounding varieties. The one in the first picture is a blue point which I’m pretty sure is variety of juniperus chinensis and the other is a grey owl which I’m pretty sure is a variety of juniperus Virginia


In the future I would love to elevate their aesthetics but I want to be sure I’m treating them correctly. Any advice would be great!

The Blue Point is a needle Juniper and should be treated as such, and yes the Grey Owl is a variety of Virginia

Thanks for the feedback! And do you know if virginiana is a mounding or running juniper?

My experience with Juniperus virginiana is that they run with extensions on the vigorous branches and apex. They will mound and make decent pads with correct pruning after they have hardened in the early summer.

Running Junipers

When we talk about running junipers, what we mean is that the juniper will extend before it mounds. It sends out whips and then you will see it grow interior growth and mound.

Some species of running junipers are listed below.

Rocky Mountain Juniper
Sierra Juniper
California Juniper
Western Juniper

Mounding Junipers

Mounding junipers will grow nice dense puffs of growth before it sends out extensions. Below is a list of a few of the mounding junipers that we use in bonsai.

Shimpaku Junipers
    Kishu
    Itoiagawa
    Toyama
Procumbans Juniper
Needle Juniper

Thanks for the detailed reply! Super helpful and exactly what I was looking for. I’ve seen how both types are treated in the library but I haven’t seen these varieties talked about I wanted to be sure I was treating them correctly for their growth habits.
