How To Choose The Best All-Year-Round Plants
Your year-round garden succeeds when you match each plant to your climate and the job it needs to do. Where you set plants — a sunny flowerbed, a shady slope, or a narrow hedge line — decides which variety will thrive.
Match the hardiness zone first
Your USDA hardiness zone tells you the coldest winter temperature a plant can survive. A plant rated for zones 6-10, like the Obsession Nandina, will not make it through a zone 4 winter. Check your zone before you order — it is the single most important spec.
Consider mature height and spread
A shrub that tops out at 4 feet works in a small border. A privacy tree that hits 40 feet does not. Look at the expected plant height and width in the specs and picture how it will fill the space in three to five years.
Check the sunlight and watering needs
Full-sun plants stretch and fade in shade. Ground covers that need moderate watering will struggle on a dry, sandy bank. Match the plant’s sunlight exposure and moisture needs to the spot you have, and you skip most common failures.

In-Depth Reviews
1. Autumn Amethyst Encore Azalea (1 Gallon) – Purple, Pink Flowering Shrub – Reblooming Rhododendron Plants
$19.98$21.99as of Jul 5, 12:01 AMA reblooming azalea that delivers purple flowers from spring through fall, not just once.
You get a compact shrub that tops out at 4 feet tall and 4 feet wide, which fits neatly into a flowerbed border or a foundation planting without overtaking the space. Because it is an Encore Azalea, it blooms in spring, then repeats through summer into fall — so you are not looking at a plain green bush for months on end.
Reviewers report a “healthy plant with blooms on arrival, rich green leaves and purple flowers,” and note the professional packaging with upright markings and handles. The item weight is 6 pounds for a 1-gallon container, giving you a well-established start. At a 4-foot mature height, it stays at 4 feet versus the Southern Living Nandina at 48 inches, but the payoff is that seasonal flower show rather than foliage alone.
Why it stands out
- Blooms spring to fall, not just one season
- Compact 4×4 size fits small spaces
- Hardy in zones 6-9 and thrives in full sun
One thing to note
- Limited to zones 6-9 — skip it if you are in a colder region
Reach for this if: You want a showy flowering shrub that gives color for most of the growing season in a manageable 4-foot package.
Look elsewhere if: You need a year-round privacy screen or ground cover — this is a compact ornamental, not a hedge.
2. Perfect Plants Thuja Green Giant 1 Gallon | Privacy Evergreen Arborvitae | Adaptable Lush Green Foliage
$24.99as of Jul 5, 12:01 AMA fast-growing evergreen that reaches 50 feet tall and stays green through every season.
If your goal is a living privacy fence that actually blocks sight lines, this is the plant. The Thuja Green Giant grows in a dense, pyramidal shape and, at full maturity, can hit 50 feet tall with a 20-foot-wide base — though you can prune it to keep it smaller. It thrives in zones 5-9, so it covers more of the US than the Azalea, and buyers report healthy trees with good root systems. One reviewer noted, “Not all of them are a full 2 feet high, but close enough,” so expect some natural size variation.
Compared to the 10-pack of smaller Thuja Green Giants below, this is a single 1-gallon starter that gives you a larger individual plant to begin with. The trade-off is that you pay per plant, making bulk screening more expensive than the multi-pack option.
What makes it strong
- Extremely fast-growing — adds 3 feet per year once established
- Evergreen foliage stays green and dense all year
- Adaptable to zones 5-9 with little maintenance needed
The trade-off
- One plant per purchase, so covering a long row gets costly
Best for: Anyone who needs a reliable, fast-growing evergreen privacy tree that thrives across a wide climate range.
pass on it if: You only have a small patio or garden — a 50-foot tree is too large for compact spaces.
3. Southern Living 2 Gal. Obsession Nandina Shrub
$31.20as of Jul 5, 12:01 AMA non-flowering shrub that uses vivid leaf color across seasons instead of blooms.
If you want year-round visual interest without relying on flowers, the Obsession Nandina delivers with bright red foliage that persists through much of the year. It stays compact at 48 inches tall, versus the Thuja Green Giant at 50 feet, and weighs 8.84 pounds as a 2-gallon shrub versus the 5-pound Blue Rug Juniper at planting. It is suited for zones 6-10 and grows in sun to part shade, with moderate watering needs.
One buyer mentioned, “Color is vibrant out of box, but undersized vs. same-size lemon lime Nandinas,” so the package size matches the spec, but it may start smaller than other varieties in the same container size. It is a slow-growing, low-maintenance shrub, and because it does not flower, there is no deadheading or bloom cleanup.
Strong points
- Year-round red foliage color without needing blooms
- Low maintenance, requires only weekly watering once established
- Compact at 48 inches, good for borders or foundation planting
Weak points
- Slow grower compared to faster shrubs like the Encore Azalea
- Limited to zones 6-10, not for cold northern winters
Reach for this if: You want a low-care shrub with striking leaf color that lasts through the seasons without needing to deadhead flowers.
Look elsewhere if: You prefer showy flower blooms — this shrub has no blossoms at all.
4. 10 Thuja Green Giant Arborvitae 7-10 inches Tall Trees
$35.55$41.00as of Jul 5, 12:01 AMTen compact starter trees that grow fast into a dense, tall privacy screen.
This is the bulk option for covering a long property line. You get 10 Thuja Green Giant trees, each shipped at 7-10 inches tall in its own potted container. With a fast growth rate of 3 feet per year and a mature height of 40 feet, they will fill out a screen quickly. Space them 6 to 7 feet apart, and owners mention strong results: one gardener in north Missouri said the trees “survived north Missouri winter, doubled in size in one year.”
At this price and quantity, the per-plant cost is lower than buying single Thuja Green Giant specimens like the Perfect Plants option — but the trade-off is size. These start at 7-10 inches tall, while one reviewer for the 1-gallon Perfect Plants option noted plants were close to 2 feet high, so you may wait an extra year for them to reach a similar height. Still, for a hedge of 10 trees, the savings are real.
Why it wins
- 10 plants in one purchase — the best value for a long row
- Fast growth at 3 feet per year once established
- Very hardy in zones 5-9, including cold winter regions
One risk to know
- Starts small at 7-10 inches, so requires patience for the first year
- One owner reported a 100% failure rate — check your zone and planting care
Best for: Large-area privacy screening where you need quantity and fast growth without paying per-plant premium prices.
Look elsewhere if: You only need one or two trees — the single-purchase option gives you a larger starter size.
5. Blue Rug Juniper Wiltonii | 3 Live Plants | Juniperus Horizontalis | Creeping Ground Cover, Low Maintenance Shrub, Drought Tolerant, Evergreen Foliage, Fast Growing, Erosion Control
$35.97as of Jul 5, 12:01 AMA low-growing, drought-tolerant juniper that spreads like a blue-green carpet to stop erosion.
If you have a sloped, sunny bank where grass will not hold, this is your solution. Blue Rug Juniper is a creeping evergreen ground cover that stays low to the ground and spreads horizontally, stabilizing soil with its dense growth. Each pack contains 3 live plants, and the set weighs 5 pounds total versus the 8.84-pound Nandina shrub. It tolerates sandy and rocky soils, requires full sun, and needs only moderate watering once established.
One large-scale buyer shared, “Bought 100 2-inch blue rug junipers for erosion project. 98% survival despite drought, hurricane, and cold.” That resilience is the selling point. The catch, also from buyers, is that the plants arrive small — “about the size of your fist” per one review — so plan for 1-2 years of establishment before they start covering ground aggressively.
What works
- Ideal for erosion control on slopes and sandy banks
- Drought tolerant and low maintenance once established
- Evergreen silvery-blue foliage provides year-round color
What to expect
- Starts small — takes 1-2 years to establish and spread
- Packaging can be hit-or-miss; some buyers reported dirt spillage
Reach for this if: You need a tough, spreading ground cover for a sunny, sloped spot where other plants struggle to hold soil.
Look elsewhere if: You want quick, instant coverage — this juniper needs patience to fill in fully over 2-3 years.
Understanding the Specs
Hardiness Zone (USDA Zone)
This is the map that tells you the average coldest winter temperature in your area. If you buy a plant for a zone colder than the one you live in, it will likely die in its first winter. Always check the hardiness zone range before ordering — it is the first filter for everything else.
Mature Height & Spread
These numbers tell you how big the plant will be at full growth, not at delivery. A Thuja Green Giant can reach 50 feet tall, which is a massive privacy tree; an Obsession Nandina tops out at 48 inches, which is a compact shrub. Picture the space you have and pick a plant whose final size fits — otherwise you will spend years pruning something that outgrows its spot.
Sunlight Exposure
Plants labeled “full sun” need at least 6 hours of direct sunlight each day to thrive. “Partial shade” means 3-6 hours. If you put a full-sun plant in a shady corner, it will stretch, fade, and fail to bloom. Match this spec to your planting site — it is as simple as watching where the sun hits your yard.
Reblooming vs Single Bloom
A reblooming plant like the Encore Azalea pushes flowers multiple times from spring through fall. A single-bloom plant flowers once and then sits green for the rest of the year. If you want constant color, pick a rebloomer. If foliage alone is enough — like the Obsession Nandina — a non-flowering shrub works fine.
