Waiting years for a mature landscape in Zone 9’s long growing season is a waste of potential. The combination of intense sun, warm nights, and a lengthy frost-free window creates an environment where the right tree can rocket from a foot-tall stick to a legitimate privacy screen or shade source in just a few seasons. The challenge is cutting through the marketing claims to find the proven performers that actually thrive in your specific microclimate without turning into a maintenance headache down the road.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. After months of cross-referencing USDA hardiness maps, growth rate studies, and thousands of aggregated owner reports, I’ve filtered the viable candidates from the duds for this specific climate zone.
Whether you need a windbreak, a visual screen, or a fast canopy for afternoon relief, this guide breaks down the top contenders for the best fast growing trees zone 9 has to offer, ranked by real-world performance and long-term reliability.
How To Choose The Best Fast Growing Trees Zone 9
Picking the right tree for Zone 9 is less about “will it survive” and more about “will it thrive under your specific conditions without outgrowing the space.” The climate here is a blessing for growth but also means certain trees can hit invasive tendencies or weak wood if you’re not careful. Focus on these non-negotiables.
Evergreen vs Deciduous for Your Goal
If your primary mission is privacy or a year-round windbreak, an evergreen like Thuja Green Giant or a fast-fill willow hybrid is the only logical choice. If you want summer shade but winter sun to warm your house, a deciduous maple or crape myrtle is a better move. Decide on that binary first — it trumps every other spec.
Mature Height and Spread Reality
A tree listed at “50 feet tall” sounds impressive in a nursery description, but that canopy will cast shade over half your yard. Measure your planting distance from structures, septic fields, and property lines before you order. A 50-foot tree needs at least 25 feet of clear radius — don’t force a giant into a corner lot.
Growth Rate Versus Wood Strength
Some of the fastest growers (willows, certain poplars) have brittle wood that sheds limbs in storms. For wind-prone areas of Zone 9, prioritize trees like Autumn Blaze Maple or Thuja Green Giant, which combine rapid vertical gain with structurally sound branching. The trade-off is usually less insane first-year growth but a safer long-term tree.

In‑Depth Reviews
7. Perfect Plants Thuja Green Giant 2ft. 8-Pack
This is the premier privacy tree for Zone 9 for a reason: it combines a fast growth rate (3-5 feet per year once established) with dense, dark green foliage that stays vibrant through our mild winters. The 8-pack provides enough material for a solid hedge line or screen when spaced 6-8 feet apart, and the 2-foot starter size gives you a head start over tiny plugs.
The pyramidal shape means it fills in from the ground up, so you aren’t staring at bare trunks for years. It thrives in zones 5-9, making it a perfect fit for the entire zone 9 region without worrying about heat stress or disease pressure common in more southerly climates. The Christmas-tree scent when crushed is a bonus.
At full maturity, this tree can hit 60 feet tall and 20 feet wide, so plan your spacing carefully. The 25-pound shipping weight per pack reflects the substantial root ball and soil these arrive with — they’re nursery-grown and ready to transplant. For a low-maintenance, long-lived screen, this is the benchmark.
What works
- Dense evergreen foliage blocks wind and noise year-round
- Grows fast in heat without becoming leggy
- 8 trees per pack for immediate hedge impact
What doesn’t
- Heavy shipping weight may cause handling delays
- Requires consistent water first 6 months to establish
4. American Red Maple Shade Tree 3ft by DAS Farms
If shade is your priority, the American Red Maple is one of the fastest deciduous options for zone 9. This 3-foot starter is double-boxed for safe shipping and is ready to plant directly in the ground — do not pot it, as these trees need room to spread their root system. It thrives in full sun and tolerates zones 3 through 9, so your specific zone 9 location is right in the sweet spot.
The growth rate is impressive: expect 2-4 feet per year, with a mature height around 60 feet and a broad, symmetrical canopy. The green summer leaves turn brilliant red in fall, providing both quick shade and seasonal color. The 30-day guarantee from DAS Farms means they stand behind the transplant process if you follow the included instructions.
One important note: this is a deciduous tree, so it will drop leaves in winter. That’s a feature if you want winter sun to warm your home. The 6-pound shipping weight and organic material features indicate a healthy, well-rooted plant. For a classic shade tree that grows fast in zone 9, this is a solid bet.
What works
- Large 3-foot starter saves 1-2 years over smaller saplings
- Brilliant red fall color in zone 9
- 30-day transplant guarantee with instructions
What doesn’t
- Deciduous — no winter privacy coverage
- Requires regular watering first few seasons
6. 6-Pack Red Flowering Crape Myrtle Trees
For ornamental value that doubles as a fast-growing screen, the red flowering crape myrtle from Crape Myrtle Guy is hard to beat in zone 9. These quart-container trees are 6-12 inches tall when shipped but rocket upward at 3-4 feet per year, reaching 20 feet at maturity. The extended blooming period from summer through early fall delivers vibrant red flowers that thrive in our heat.
The exfoliating bark provides winter interest even after the leaves drop, and the trees are specifically suited for southern states — they laugh at the humidity and intense sun of zone 9. The 6-pack allows you to create a flowering hedge or a clustered grove effect. They tolerate sandy soil and full sun, making them adaptable to various lot conditions.
One detail that matters: plants shipped in winter will be dormant and leafless, but they resume growth vigorously in spring. The quart container size means they need a season to size up before you see the explosive growth. For a combination of fast vertical gain and spectacular summer color, this is a top pick.
What works
- Vibrant red blooms all summer long
- Fast 3-4 ft per year growth rate
- Six trees for a substantial visual impact
What doesn’t
- Quart containers mean smaller initial size
- Deciduous — bare in winter if not pruned
3. 10 Thuja Green Giant Arborvitae 7-10 Inches
For a budget-friendly way to establish a large hedge line, this 10-pack of Thuja Green Giant arborvitae at the 7-10 inch range is a solid entry point. These are shipped as potted plants in their soil, which reduces transplant shock compared to bare-root options. The growth rate of 3 feet per year once established means you’ll have a 6-foot screen in roughly two seasons.
Hardy in zones 5-9, these are fully suitable for your climate. Space them 6-7 feet apart for a quick screen, and they will mature to 40 feet tall and 15 feet wide — large enough for substantial privacy but shorter than the Perfect Plants version, which makes them easier to prune if needed. The partial shade tolerance gives flexibility for less-than-ideal placement.
The main caveat is the shipping guarantee: Panter Nursery offers a 5-day window for claims, and plants purchased outside your recommended zone are not covered. For zone 9, you’re fine, but be prepared for potential dormancy or minor stress during extreme heat shipping. For the price per tree, this is an excellent value for mass planting.
What works
- 10 trees for a low per-unit cost
- Potted in soil for less transplant shock
- Consistent 3 ft per year growth
What doesn’t
- 7-10 in size is small — needs patience
- 5-day guarantee window is tight
5. 50 Hybrid Willow Trees – Austree – Fastest Growing
If you need instant impact — I mean truly insane growth — the hybrid willow from CZ Grain is the species that grows up to 10 feet per year. Yes, you read that right. This 50-tree pack is ideal for erosion control, drying up damp areas, or creating a dense privacy barrier in record time. They are deer resistant and produce no seeds or cotton, keeping them tidy.
The trees are shipped as bare-root sticks, and the 50 count is enough to cover a substantial property line. They thrive in full sun with moderate water and are incredibly easy to establish. CZ Grain includes detailed instructions and video links to maximize your success. For environmental purposes like air filtration and slope stabilization, these are unmatched.
The trade-off is significant: willows have brittle wood that can shed branches in storms, and they are deciduous, so privacy is seasonal. They also spread aggressively via roots, so keep them away from septic systems and foundations. For a temporary fast fill or a wetland restoration project, this is the ultimate option. For a permanent landscape tree, think twice.
What works
- Unbelievable 10 ft per year growth potential
- 50 trees for massive coverage
- Deer resistant and seedless
What doesn’t
- Brittle wood prone to storm damage
- Invasive root system near infrastructure
2. 24 Jumbo Hybrid Willow Cuttings – CZ Grain
For the absolute cheapest way to get a fast privacy hedge, these jumbo hybrid willow cuttings from CZ Grain deliver. At roughly 10 inches tall with thick 5/8 to 1+ inch root stock, they are bigger than typical cuttings, which maximizes first-year growth. The 24-count pack is perfect for property lines, noise barriers, or erosion control on slopes.
The cuttings are easy to establish — just stick them in moist soil in full sun, keep them watered, and they take off. They grow into tall, elegant willow trees that provide natural shade and privacy faster than almost any other option. The thicker cuttings mean less die-off and more vigorous early growth compared to thinner willow sticks.
Same caveats as the 50-pack: willows are messy, weak-wooded, and deciduous. They also need consistent moisture to thrive, so if your soil is dry or clay-heavy, they may struggle. For a low-cost, high-speed solution where you don’t mind replanting after a storm or want a temporary screen, this is hard to beat for the price.
What works
- Thick 5/8-1 in root stock for strong start
- 24 cuttings for extensive coverage
- Extremely easy to plant and establish
What doesn’t
- Not a long-term landscape tree
- Requires consistent moisture to thrive
1. Maple Autumn Blaze Tree – 1 gal Nursery Pot
The Autumn Blaze Maple is a hybrid known for its fast growth and absolutely spectacular fall color — you get bright orange and red foliage that rivals any tree in the landscape. This 1-gallon nursery pot is a young starter, but the genetics are proven to hit 40-50 feet at maturity with a symmetrical, rounded canopy that provides excellent shade.
It is drought-tolerant once established and requires regular watering for the first few years. The root system is strong, and the branching is more structurally sound than silver maples or willows, making it a safer choice near your home. It prefers acidic, well-draining soil and full sun for the best fall color.
The primary downside is that it’s officially rated for zones 3-8, not 9. Zone 9 may be at the edge of its heat tolerance, and the fall color may be less intense in very warm autumns. Also, it cannot be shipped to California, Arizona, Alaska, or Hawaii due to agricultural restrictions. For zone 9 gardeners in the deep south, this is a gamble — the crape myrtle or red maple may be safer bets.
What works
- Fast growth with strong wood structure
- Brilliant orange-red fall display
- Drought tolerant once established
What doesn’t
- Zone rating stops at 8 — risky for zone 9
- Cannot ship to CA, AZ, AK, or HI
Hardware & Specs Guide
Growth Rate Per Year
This is the single most important metric for “fast growing” trees. Hybrid willows claim up to 10 feet per year, but this comes at the cost of weak wood and short lifespan. Thuja Green Giants deliver a more modest but sustainable 3-5 feet per year with dense wood that survives storms. Red maples and crape myrtles sit in the 2-4 ft per year range and offer better ornamental value. Always ask: “Do I want speed at any cost, or a good balance of speed and strength?”
Mature Height and Spread
Zone 9 buyers frequently underestimate how big these trees get. A 50-foot tree is not a “small accent” — it’s a dominant landscape feature. Measure your planting location from building foundations (at least 15-20 ft), septic drain fields (25 ft for willows), and overhead power lines. If you have limited space, the crape myrtle’s 20-foot mature height is a much better fit than the American Red Maple’s 60-foot spread.
