‘Dallas Red’ lantana is a desert-adapted ground cover that’s carpeted with fiery red flowers all summer long. Here’s everything you need to know about planting and taking care of this South American hybrid.
‘Dallas Red’ lantana (Lantana x ‘Dallas Red’) is an attractive, low-maintenance ground cover that forms a shrub-like mound covered with flowers that start true red, then gradually turn orange and yellow.
It’s not native to the desert southwest, but is tolerant of our harshest conditions — full sun, poor soil, urban pollution, and drought.
‘Dallas Red’ attracts many important pollinators — bees, hummingbirds, moths, and butterflies. The berries, which are toxic to mammals, are enjoyed by birds.
Why I Like This Plant
- Brilliant flowers spring through fall
- Grows fast
- Low water use, low maintenance
- Long-lived, up to 20 years
- Tolerates challenging urban settings
- Attracts pollinators
Things to Watch Out For
Like all lantanas, ‘Dallas Red’ is covered with irritating hairs. Some people find lantana mildly irritating, while others develop a full-blown allergic reaction when in contact with it.
Since it dies back from cold, it’s not all that attractive during the winter when it resembles a pile of dead sticks.
All parts of lantana are considered toxic to people, dogs, cats, and horses.
Optimal Growing Conditions
If you’re thinking of adding a ‘Dallas Red’ to your garden, you need to find a suitable place that will keep your plant healthy and looking good… while minimizing maintenance for you.
Here are the key factors to keep in mind.
Temperature
‘Dallas Red’ lantan should be grown in USDA Hardiness Zones 8 – 11. Plants thrive in summer heat and survives temperatures as low as 20℉. But once the temperature drops below freezing, it will lose its leaves and flowers until the following spring.
Sun Exposure
‘Dallas Red’ thrives in full sun, even the reflected sun off of sidewalks, driveways, or walls. While it can be grown in part shade, the flowers are more colorful in full sun.
Size and Growth Rate
‘Dallas Red’ is a fast-growing ground cover that will grow to be 3 feet tall and 4 feet wide. Some growers report that it can reach its full size within a year.
Soil
‘Dallas Red’ lantana is definitely not picky about soil, as long as it’s well-draining. It will grow in everything from sand to clay, and unlike native plants, which prefer alkaline soil, it will happily grow in either acidic or alkaline soil.
If you have clay soil or a low spot in your yard that tends to stay wet during the monsoon,’Dallas Red’ is one lantana hybrid doesn’t mind moist growing conditions, as long as there’s no standing water.
Other Location Considerations
Since it can be irritating to touch and toxic for pets, plant it where kids and pets can’t get at it. It does great in hanging baskets and pots. Gardeners in colder climates often grow them in containers as annuals.
Since it loses its leaves, it’s not a good choice to plant near a pool.
No desert plant is completely “critter-proof.” If animals get hungry enough, they’ll eat almost anything! But deer, javelinas, and rabbits usually leave lantana alone, so you can plant it in your front yard or other unenclosed area.

How to Plant
The rule of thumb when planting any ground cover in the desert is to dig a hole twice as wide as the root ball but no deeper. Amending the soil is not recommended. Counterintuitively, backfilling with the same native soil you just dug up helps your plant develop a stronger root system.
When to Plant
Since lantana is frost-sensitive, it’s generally recommended that you plant it in the spring after the danger of frost has passed. However, I’ve planted lantana in both the spring and the fall with equal success.
How to Care for ‘Dallas Red’
Whether you’ve recently planted a lantana or have an existing one in your yard, here’s how to take care of it to keep it healthy and looking its best.
How to Water
Once you’ve got your lantana in the ground, watering is your most immediate concern.
The University of Arizona recommends watering newly planted ground covers every 2 to 3 days for the first 2 to 4 weeks. After that, water once a week for the next two weeks, and then every 10 – 14 days after that.
During the winter, while it is dormant, it may not need any water, provided you’ve had winter rains. If not, water every 3 to 6 weeks.
How much water you should give your plant with each watering depends on the diameter of your plant and will change as it grows. You can use this chart as a guide.
| 1 foot diameter | .5 gallons |
| 2 feet diameter | 2 gallons |
| 3 feet diameter | 3.5 gallons |
| 4 feet diameter | 5 gallons |
Should You Fertilize?
Most desert plants don’t need fertilizing, but since ground covers are often planted near other plants, they have to compete for nutrients. To ensure maximum growth and blooms, the Arizona-Sonora Desert Museum recommends fertilizing lantana twice per year, in the early spring and early fall.
How to Prune
Lantana ‘Dallas Red’ benefits from a hard prune in the spring after the last frost date. Don’t be afraid to take your plant all the way down to the ground. It grows vigorously and will quickly rebound to its former size.
During its growing season, you can prune lightly anytime to control its size or shape.
Caution!
Spraying with insecticidal soap or dish detergent can kill lantanas.
Other Red Lantanas to Consider
‘Dallas Red’ is said to have the truest red flowers of all the lantana hybrids, but it’s not always easy to find. If you can’t find ‘Dallas Red’ locally, here are some other red lantanas to consider:
- Proven Winners: Luscious Royale Red Zone or Bandana Red lantanas
- Monrovia: Radiation, Fiesta Picante, or Hot-Blooded lantanas
Plant Lover Facts
‘Dallas Red’ is a hybrid of Lantana camara, which has a large native range that extends from the northern half of South America, through Central America, and into Mexico. While generally not considered a native plant, its natural range does include parts of the Sonoran Desert in Mexico, making it a “near native.”
