Which juniper is known for its compact form?

Juniperus horizontalis 'Plumosa Compacta' is recognized for its compact form, making it a popular choice in landscaping where a low, spreading habit is desired. This cultivar typically grows to a height of about 1 to 1.5 feet and spreads to about 4 to 5 feet wide, allowing it to effectively cover ground without growing too tall. Its dense, blue-green foliage holds its color throughout the year, providing consistent aesthetic appeal in various landscape settings.

In contrast, while the other juniper varieties listed may have their own attractive characteristics, they do not share the same compact growth pattern. For instance, Juniperus conferta 'Blue Pacific' is known for its spreading nature but tends to grow taller and more open. Similarly, Juniperus davurica 'Expansa' and Juniperus horizontalis 'Wiltonii' also exhibit growth habits that can be more upright and expansive, making them less ideal representations of a compact form compared to 'Plumosa Compacta'. This distinction in growth habit is important for selecting the right plant for specific landscape design needs.
