Best Freeze-Resistant Shrubs for Houston: Expert Guide from a Texas A&M Horticulturist
If you've lived in Houston or Sugar Land for a while, you know our winters have been full of surprises lately. The devastating February 2021 freeze—when temperatures plummeted into the teens for days—changed everything Houston homeowners thought they knew about cold-hardy landscaping. Temperatures dipping into the 20s and below can take out even plants we once considered "tough" for our area.
Every year, frustrated homeowners tell us the same thing: "I'm tired of replacing shrubs that can't handle the cold!" They've lost hundreds or even thousands of dollars in landscape plants that couldn't survive our increasingly unpredictable winter weather.
I'm Todd Farber, a Houston native and Texas A&M horticulture graduate (Class of '91). For over 30 years, I've been helping homeowners throughout Sugar Land, Missouri City, and Fort Bend County create beautiful, resilient landscapes that thrive in both our brutal summer heat and those unexpected hard freezes.
The 2021 freeze taught us valuable lessons about which shrubs can truly handle Houston's climate extremes. Some plants we'd grown for decades without issue suffered severe damage or died completely. But other shrubs sailed through multiple days below 20°F without even dropping a leaf.
So before another freeze hits, here's the Garden Guy list of the best freeze-resistant shrubs for Houston—evergreen, hardy, and ready for anything our Gulf Coast weather throws at them.
What Makes a Shrub "Freeze-Resistant" in Houston?
Before we dive into specific plants, it's important to understand what we mean by "freeze-resistant" in the Houston climate. We're not talking about plants that handle brief dips to 32°F—most shrubs can do that. We need shrubs that can survive:
Sustained freezes (24+ hours below freezing)
Hard freezes (temperatures in the low 20s or teens)
Multiple freeze/thaw cycles that stress plants
Rapid temperature swings from 75°F to 25°F in 24 hours
True freeze-resistant shrubs for Houston are typically rated for USDA Zone 8a or lower, meaning they can handle winter lows of 10-15°F. While Houston is officially Zone 9a (20-25°F winter lows), the 2021 event proved we need to plan for colder extremes.
Top Freeze-Resistant Evergreen Shrubs for Houston Landscapes
1. Yaupon Holly (Ilex vomitoria)
Cold Hardiness: Zone 7 (0-10°F)
Why It's Perfect for Houston: This Texas native is nearly indestructible. Yaupon holly survived the 2021 freeze without damage across the Houston area, even when temperatures stayed in the teens for multiple days.
Landscape Benefits:
Evergreen year-round with small, dark green leaves
Produces red berries (on female plants) that birds love
Tolerates Houston's heavy clay soil, drought, and flooding
Available in standard, dwarf, and weeping forms
Grows 15-25 feet (standard) or 3-5 feet (dwarf varieties)
Best Uses: Foundation plantings, privacy screens, specimen plants, or naturalizing in shaded areas. Dwarf yaupon makes an excellent low hedge that rarely needs pruning.
Todd's Note: If I could only recommend one freeze-proof shrub for Houston, this would be it. Native plants evolved here for a reason—they handle everything our climate dishes out.
2. Wax Myrtle (Morella cerifera)
Cold Hardiness: Zone 7 (0-10°F)
Why It's Perfect for Houston: Another Texas native superstar, wax myrtle is fast-growing, adaptable to wet or dry conditions, and provides excellent screening while handling hard freezes with ease.
Landscape Benefits:
Fast growth rate (3-5 feet per year when young)
Aromatic evergreen foliage
Tolerates poor drainage better than most shrubs
Attracts beneficial wildlife
Can be maintained as large shrub (8-12 feet) or small tree (15-20 feet)
Best Uses: Privacy screens, naturalized areas, bioswales and rain gardens, transitional plantings between yard and natural areas.
Maintenance Tip: Wax myrtle benefits from occasional pruning to maintain density. Without pruning, it tends to become leggy at the base.
3. Dwarf Burford Holly (Ilex cornuta 'Dwarf Burford')
Cold Hardiness: Zone 6 (0 to -10°F)
Why It's Perfect for Houston: Compact growth habit with exceptional cold tolerance. This shrub thrives in Houston's summer heat while shrugging off our worst winter weather.
Landscape Benefits:
Dense, rounded form with glossy evergreen leaves
Bright red berries in winter (doesn't require pollinator)
Grows 6-8 feet tall and wide (easily maintained smaller)
Handles full sun to partial shade
Deer resistant
Best Uses: Foundation plantings, low hedges, mass plantings, or as a specimen shrub in mixed borders.
Design Tip: Plant Dwarf Burford holly in groups of three or five for maximum visual impact while creating a cohesive landscape design.
4. Possumhaw Holly (Ilex decidua)
Cold Hardiness: Zone 5 (-20 to -10°F)
Why It's Perfect for Houston: While technically deciduous (loses leaves in winter), possumhaw deserves mention for its exceptional cold tolerance and spectacular winter interest.
Landscape Benefits:
Brilliant red or orange berries persist all winter
Native to Texas bottomlands and creek edges
Tolerates wet, poorly drained Houston clay soil
Multi-season interest with berries attracting winter birds
Grows 12-15 feet tall
Best Uses: Naturalized areas, water features, specimen plantings where winter berries create focal points, mixed borders with evergreens.
Wildlife Value: The berry display on female plants is stunning from November through February and provides critical food for overwintering birds.
5. Loropetalum (Chinese Fringe Flower)
Cold Hardiness: Zone 7-8 (10-20°F depending on variety)
Why It's Perfect for Houston: While not quite as cold-hardy as our native hollies, loropetalum performed surprisingly well during the 2021 freeze, with most established plants surviving or recovering quickly.
Landscape Benefits:
Stunning burgundy or purple foliage (or green varieties available)
Pink or white fringe-like flowers in spring and sporadically year-round
Fast-growing and low-maintenance
Available in sizes from 3-foot dwarfs to 10-foot standards
Excellent color contrast in landscapes
Best Uses: Foundation plantings, hedges, mass plantings, specimen shrubs for year-round color.
Cold Weather Performance: Established loropetalum in protected locations survived 2021 with minimal damage. Young plants or those in exposed sites may suffer tip dieback but typically recover. The purple varieties are slightly more cold-hardy than green forms.
6. Nellie R Stevens Holly (Ilex x 'Nellie R Stevens')
Cold Hardiness: Zone 6 (-10 to 0°F)
Why It's Perfect for Houston: One of the best fast-growing evergreen privacy screens that can handle both Houston heat and hard freezes.
Landscape Benefits:
Fast growth rate (2-3 feet per year)
Pyramidal shape ideal for screening
Dense evergreen foliage year-round
Bright red berries in fall/winter
Can reach 15-25 feet tall and 8-12 feet wide
Drought tolerant once established
Best Uses: Privacy screens, property line plantings, large hedges, specimen evergreen trees.
Spacing Tip: For privacy screening, plant Nellie R Stevens holly 6-8 feet apart. They'll fill in within 3-4 years while maintaining individual character.
7. Eagleston Holly (Ilex x attenuata 'Eagleston')
Cold Hardiness: Zone 6 (-10 to 0°F)
Why It's Perfect for Houston: Similar cold tolerance to Nellie R Stevens but with a more columnar growth habit, making it perfect for narrow spaces.
Landscape Benefits:
Columnar form (up to 20 feet tall, 10-12 feet wide)
Dense evergreen foliage
Red berries on female plants
Excellent for vertical accents and narrow spaces
Handles Houston clay soil well
Best Uses: Narrow side yards, vertical accents, tall hedges, framing entryways or corners.
Comparison Note: Both Eagleston and Nellie R Stevens are excellent choices. Choose Eagleston for tighter spaces and more formal, upright form; choose Nellie R Stevens for faster screening and broader, more natural pyramidal shape.
8. Foster Holly (Ilex x attenuata 'Fosteri')
Cold Hardiness: Zone 6 (-10 to 0°F)
Why It's Perfect for Houston: Dense pyramidal form with exceptional cold hardiness and heat tolerance.
Landscape Benefits:
Dark green evergreen foliage
Naturally pyramidal shape
Red berries add winter interest
Fast growth rate
Reaches 20-25 feet tall, 10-15 feet wide
Best Uses: Large screening, specimen evergreen, property borders, background plantings.
9. Indian Hawthorn (Rhaphiolepis indica)
Cold Hardiness: Zone 8 (10-20°F)
Why It's Perfect for Houston: Lower growing shrub that handled the 2021 freeze surprisingly well, especially established plants in protected locations.
Landscape Benefits:
Compact growth (3-6 feet depending on variety)
Spring flowers in pink, white, or red
Low maintenance and drought tolerant
Evergreen foliage with reddish new growth
Blue-black berries attract birds
Best Uses: Foundation plantings, low hedges, mass plantings, containers, parking lot islands.
Freeze Performance: Some tip damage occurred in 2021 on exposed plants, but most recovered quickly. Plant in locations with some protection from north winds for best results.
10. Texas Sage (Leucophyllum frutescens)
Cold Hardiness: Zone 7 (-10 to 0°F)
Why It's Perfect for Houston: Extremely drought and heat tolerant with better cold hardiness than many people realize.
Landscape Benefits:
Silvery-gray evergreen foliage
Purple, pink, or white flowers after rain
Extremely drought tolerant once established
Low maintenance, rarely needs pruning
Grows 4-8 feet tall and wide
Best Uses: Xeriscape gardens, full sun areas, low-water landscapes, specimen plantings, informal hedges.
Important Note: Texas sage needs excellent drainage. In heavy Houston clay, plant on berms or raised beds to prevent root rot during wet periods.
Shrubs to AVOID in Houston if You're Worried About Freezes
Not every popular Houston shrub can handle hard freezes. Here are plants that consistently suffered severe damage or death during the 2021 freeze:
Hibiscus (Tropical Varieties)
While beautiful during our long growing season, tropical hibiscus cannot survive hard freezes. Even root-hardy varieties (that grow back from roots) lost all top growth in 2021 and many didn't return.
Better Alternative: Rose of Sharon (Hibiscus syriacus) is cold-hardy to Zone 5 and provides similar large flowers, though it's deciduous.
Bougainvillea
These stunning flowering vines are only hardy to 30°F. Anything below that causes damage; temperatures in the 20s kill them to the ground. Most Sugar Land bougainvilleas died completely in 2021.
Better Alternative: Confederate jasmine (Trachelospermum jasminoides) provides evergreen coverage with fragrant white flowers and is cold-hardy to 0°F.
Ixora
Tropical shrub with beautiful flower clusters, but completely intolerant of freezing temperatures. Extensive damage occurs at 32°F; plants die at temperatures in the 20s.
Better Alternative: Dwarf azalea varieties provide similar spring flower impact with cold hardiness to -10°F.
Plumeria (Frangipani)
Beautiful fragrant flowers and tropical appearance, but zero cold tolerance. Even brief freezes cause damage; sustained cold kills them.
Better Alternative: If you love the fragrant flowers, consider frost-hardy gardenia varieties like 'Frostproof' (hardy to 0°F) or Confederate jasmine.
Crotons
Popular for colorful foliage but extremely cold-sensitive. Damage begins at 40°F; anything below 32°F causes severe damage or death.
Better Alternative: Purple loropetalum provides year-round colorful foliage with much better cold tolerance.
How to Protect Shrubs During Houston Freezes
Even cold-hardy shrubs benefit from protection during extreme freezes, especially young plants that haven't fully established:
Before the Freeze
Water Deeply: Moist soil holds heat better than dry soil. Water thoroughly 24-48 hours before a predicted freeze.
Mulch: Apply 3-4 inches of mulch around the root zone (keep away from stems). This insulates roots and moderates soil temperature.
Avoid Pruning: Don't prune shrubs in fall or early winter. Dead-looking branches may protect living tissue beneath.
During the Freeze
Cover Sensitive Plants: Use frost cloth, old sheets, or blankets (not plastic) draped over plants and secured to the ground. Remove during the day if temperatures rise above freezing.
Add Heat Source: For extremely valuable or borderline-hardy shrubs, place outdoor Christmas lights (incandescent, not LED) under covers for additional warmth.
Protect Potted Plants: Move container plants to protected locations like covered patios or garages.
After the Freeze
Don't Prune Immediately: Wait until spring to assess damage. What looks dead might recover from the roots.
Resume Normal Care: Once temperatures stabilize, return to normal watering schedules.
Fertilize in Spring: Don't fertilize damaged plants until they show new growth in spring.
Designing a Freeze-Resistant Houston Landscape
Creating a beautiful landscape that survives our climate extremes requires strategic planning:
Layer Your Plantings
Background (8-20+ feet): Nellie R Stevens holly, Eagleston holly, Foster holly, wax myrtle
Mid-Layer (4-8 feet): Dwarf yaupon holly, loropetalum, Texas sage
Foreground (2-4 feet): Indian hawthorn, dwarf loropetalum varieties, compact hollies
Create Microclimates
Protected Zones: Areas near house foundations, protected by walls or fences, create warmer microclimates suitable for slightly less hardy plants.
Exposed Areas: North-facing and open areas experience coldest temperatures. Reserve these for the toughest natives like yaupon holly and wax myrtle.
Mix Textures and Colors
Don't create a monotonous green wall. Combine:
Different leaf textures (fine yaupon vs. bold holly leaves)
Contrasting foliage colors (purple loropetalum with green hollies)
Deciduous and evergreen (possumhaw winter berries among evergreens)
Varying heights and forms
Plan for Year-Round Interest
Spring: Loropetalum flowers, Indian hawthorn blooms, fresh new growth
Summer: Lush green foliage, dense screening, Texas sage flowers after rain
Fall: Holly berries begin coloring, possumhaw leaves turn yellow
Winter: Red berries on hollies, possumhaw full berry display, evergreen structure
The Investment Value of Freeze-Resistant Shrubs
Quality freeze-resistant shrubs cost more upfront than tropicals or annuals, but the long-term value is undeniable:
Initial Cost: $25-75 per shrub (3-gallon containers) for most species
Lifespan: 20-50+ years with proper care
Replacement Frequency: Zero (vs. replacing tropicals every few years)
Compare this to homeowners who lost $3,000-10,000+ worth of tropical landscape plants in a single freeze event. Investing in cold-hardy shrubs is landscape insurance.
Return on Investment
Quality landscaping with freeze-resistant shrubs provides:
Curb Appeal: Increases home value 7-15%
Energy Savings: Strategic placement reduces heating/cooling costs
Privacy: Living screens are more attractive than fences
Wildlife Habitat: Native plants support local ecosystems
Peace of Mind: No more winter plant anxiety
Planting and Care Tips for Maximum Cold Hardiness
Best Planting Time in Houston
Fall (October-November): Ideal for establishing roots before winter
Early Spring (March): Second-best option as plants break dormancy
Avoid: Summer planting stresses shrubs; winter planting doesn't allow establishment before freezes
Soil Preparation for Houston Clay
Houston's heavy clay soil needs amendment for optimal shrub health:
Test Drainage: Dig a hole 12 inches deep, fill with water, and see how long it takes to drain. If water remains after 4 hours, you have poor drainage.
Amend Soil: Mix 3 inches of quality compost into the top 12 inches of native soil. Don't create a "bathtub" of pure compost—shrubs need to adapt to native conditions.
Raise if Needed: For very poor drainage, plant on berms or raised beds 8-12 inches high.
Mulch Properly: Apply 2-3 inches of hardwood mulch, keeping it 2-3 inches away from stems.
Watering Schedule
First Year: Water deeply twice weekly during growing season, once weekly in winter (if no rain)
Established Plants: Most native shrubs need watering only during drought once established
Pre-Freeze: Always water deeply before predicted freezes
Fertilization
Spring (April): Apply slow-release fertilizer as new growth begins
Summer (June): Optional second application for heavy feeders like loropetalum
Fall/Winter: No fertilization—you don't want to encourage tender new growth before freezes

Why Trust Garden Guy's Plant Recommendations?
The 2021 freeze was a turning point for Houston landscaping. We saw firsthand which plants thrived, which survived, and which failed completely across hundreds of Sugar Land and Fort Bend County properties.
Since 1991, I've been helping Houston homeowners create landscapes that work with our unique climate—not against it. That means:
Selecting plants proven to handle Zone 8 extremes
Understanding Houston's heavy clay soil challenges
Designing for both summer heat and winter cold
Recommending native plants adapted to Gulf Coast conditions
Avoiding trendy tropicals that can't survive our winters
Every shrub on this list has been personally tested in Houston landscapes—many in my own yard and clients' properties throughout Sugar Land, Missouri City, and surrounding areas.
Local Availability: Where to Find These Shrubs
Most freeze-resistant shrubs are readily available at Houston-area nurseries:
Spring (March-May): Best selection and healthiest stock
Fall (October-November): Good selection, ideal planting time
Summer/Winter: Limited selection, avoid planting during these periods
Shopping Tips:
Look for plants in 3-gallon or larger containers—better established root systems
Check for signs of stress (yellow leaves, sparse growth, insects)
Buy locally grown stock when possible—already adapted to Houston conditions
Ask about variety names for hollies—dwarf vs. standard makes a big difference
Common Questions About Freeze-Resistant Shrubs
Q: Will these shrubs survive another 2021-style freeze?
A: The shrubs listed here all survived 2021 with minimal to no damage when properly established. However, young plants (less than 1 year in ground) may need protection during extreme events.
Q: How long until shrubs reach mature size?
A: Most reach 50-75% of mature size within 3-4 years with proper care. Fast growers like wax myrtle and Nellie R Stevens reach screening height (6-8 feet) within 2-3 years.
Q: Do I need to cover these shrubs during freezes?
A: Established plants don't need covering. Young plants (first year) benefit from protection during hard freezes (below 25°F), especially in exposed locations.
Q: Can these shrubs handle Houston summer heat?
A: Absolutely! All recommended shrubs thrive in our summer heat and humidity. Native plants like yaupon holly and wax myrtle are especially well-adapted to our climate extremes.
Q: Are these shrubs deer-resistant?
A: Most hollies are deer-resistant due to spiny leaves. Wax myrtle and Texas sage are also typically avoided by deer. Loropetalum may be browsed if deer are hungry.
