One of the best ways to get privacy from your neighbors, or to screen unwanted views is to plant a hedge. But which shrubs make the best screens? If you have a small garden, I’d like to steer you in a direction that cuts down your overwhelm:
Oh no, hundreds of plant to choose from!
No, not really. Especially when you’re looking for the best choice for a small space.
First, take a look at the most important factors that will immediately reject most plant choices. Or, factors that will matter to you most.
What Matters Most
- Being Evergreen
- Plant’s Mature Height and Width
- Speed of Growth
- Roots and Invasiveness
- Small Leaves versus Big Leaves
First of all, for privacy/screening purposes you want to select an evergreen shrub – one that’s going to remain in leaf all year long. Secondly, knowing the speed of growth, and a plant’s size at maturity (height and spread) gives a clue as to how much pruning and clipping you might need to be doing (especially if a formal clipped topiary is desired). The following 11 selections include these details so that you can make a more informed decision.
Shrub Choices: Small Leaves
About Pittosporum tenuifolium varieties: Below are three varieties of P. tenuifolium that work well as hedges for small spaces. These varieties have been around for a while and are some of the most popular to find and buy, at least out west. All have spring blooming small, fragrant flowers followed by tiny orange fruits, which are insignificant, especially if you’re clipping a lot. All are good for both formal and informal gardens. And finally, All are long lived and fast growers. To keep them dense and well structured regular pruning is important.
1. Pittosporum tenuifolium (Kokuhu) Zones: 8 – 11. Besides the varieties to follow, the species, Pittosporum tenuifolium, is a good hedge plant, so I’ve included to the list. *That said, the size can be overpowering for a small garden so consider this choice only if you want a taller hedge, say 10 – 11 feet, or, higher, and don’t mind maintaining it. Mature size: 15 – 25 feet high x 10 – 15 feet wide. Medium green leaves are small, glossy, oval and pointed. Exposure: full sun to part shade. Plant spacing: 3 – 4 feet. Growth rate: fast. From a 5 gallon container this plant can reach 6 to 7 feet in a year.

For fragrant flowers, you can go with looser pruning in spring and summer.
11. Ficus retusa nitida (Indian Laurel Fig) Zones: 10 – 11. Though often grown as a tropical evergreen tree, its dense foliage and upright branches make it an excellent candidate for a tightly clipped hedge. This makes the list, but only in carefully chosen locations, or with appropriate preparation due to its invasive and aggressively spreading root system. Leathery leaves are dark green, large and glossy. Mature size: 20 – 60 feet high x 20 – 60 feet wide. Exposure: full sun to part shade. Water: moderate. Plant spacing: 2 -3 feet. Growth rate: fast.

Conclusion
Let’s face it, you don’t want to choose a screening hedge plant willy nilly for a small space. Start by planning ahead. First decide how tall you want or need the hedge to be, and it’s a good idea to think in terms of feet. If you’re maintaining the hedge yourself, keeping it lower, say…6 to 8 feet tall, will make it much quicker and easier to maintain. If you need a taller screen, not a problem, there are no rules. Take a look at the 11 choices here and I hope you find one that you like. 🙂

Where To Buy:We’ve included our Etsy, Amazon and NatureHills Nursery
Plant availability varies. We try to keep our links up to date. Etsy merchants currently have a good selection of Pittosporum tenuifolium, Thuja occidentalis and Ligustrum japonicum
When it comes to maintaining the shape of a hedge, we love our Japanese hedge shears. After using several other brands over the years, and then getting introduced to a pair of high quality Japanese hedge clippers, there was no turning back, (nor was there any comparison.) Though the exact brand and model of our clippers is not available, the Okatsune Precision Hedge Shears are very similar and similar in cost. Truth be told, we’re very hard on our tools, so they need to be tough. The blades are made of forged steel (the kind they use for Samurai swords, if that gives you an idea of how sharp these are) with Japanese white oak handles. And sharp they do stay, for months. That sharpness and their precision really help speed up any pruning job. If you read through the reviews on Amazon you’ll see that everyone gave these shears 5 stars. They all say things like ‘best shears ever’ or ‘wish I bought a pair of these years ago’ or ‘It’s like using a lightsaber to trim your hedge’ – our thoughts exactly!! 🙂
