Phoenix's Best Golden-Yellow Blooming Groundcover for Nonstop Full-Sun Color

New Gold Lantana (Lantana × hybrida 'New Gold') is one of the most reliable and vibrant flowering groundcovers available for Phoenix Valley landscapes. Its solid golden-yellow blooms cover the plant in a dense, continuous display from spring through fall — and in Phoenix's mild winters, it often keeps blooming nearly year-round. As a sterile hybrid, New Gold puts all its energy into flowers rather than fruit, making the bloom display exceptionally prolific. It grows 12–18 inches tall and spreads 24–36 inches wide, creating a bright, low-maintenance carpet of gold wherever it's planted. Whether you're covering a sunny slope in Mesa, edging a driveway in Chandler, or creating a mass color planting in Glendale — New Gold Lantana is one of the top performers in the Arizona desert landscape.

New Gold Lantana Uses in Phoenix Landscapes

Nonstop Color for Sun-Baked Beds

New Gold Lantana's sterile hybrid status means it produces no viable seed — so instead of putting energy into fruit production, it just keeps blooming. The result is one of the most prolific flowering groundcovers for Phoenix. The solid golden-yellow color doesn't fade or change with age like multi-toned Lantanas, giving beds a consistently bold, vibrant look from spring through fall. Mass plant 2–2.5 feet apart for full coverage in one growing season in Scottsdale and Phoenix front yards.

Butterfly and Pollinator Garden

Although New Gold is a sterile hybrid, it still produces abundant nectar that attracts butterflies, bees, and other pollinators. Monarchs, swallowtails, and Gulf fritillaries are particularly attracted to its dense golden flower clusters throughout the blooming season. Pair with Radiation Lantana, Dallas Red Lantana, or Purple Trailing Lantana for a mixed-color pollinator garden that provides color across the warm color spectrum in Tempe, Peoria, or Surprise.

Low-Water Border and Slope Coverage

At just 12–18 inches tall, New Gold Lantana makes an excellent low border along walkways, driveways, and landscape beds. Its spreading habit fills in gaps quickly, crowding out weeds and reducing the need for landscape fabric. On slopes, it provides effective erosion control while delivering continuous color. For a 20 ft slope: 7–8 plants at 2.5 ft spacing; for a 40 ft driveway border: 15–16 plants.

Companion Planting with Other Lantanas

New Gold's pure yellow blooms pair beautifully with the warm orange-red tones of Radiation Lantana and the deep red of Dallas Red Lantana. Planting all three together creates a fiery, multicolored groundcover display that mimics the look of a sunset across Phoenix landscape beds. Combine with White Trailing Lantana and Purple Trailing Lantana for a full-spectrum color groundcover garden.

Best Time to Plant New Gold Lantana in Phoenix

Fall (October–November) is the ideal planting time — warm soil supports root development while cooler air temperatures reduce transplant stress. Plants establish over the winter months and are ready to bloom vigorously when spring arrives. Spring planting (February–April) is also effective. Summer planting is possible — Lantana is tough — but the intense heat increases water demand during establishment and can slow early growth significantly.

How to Plant New Gold Lantana

1. Dig wide, not deep — dig a hole 2–3x the root ball width at the same depth as the container.
2. Check for caliche — break through any hardpan layer to ensure proper drainage below the root zone.
3. Backfill with native soil — a light 20% organic amendment is acceptable; avoid heavy compost mixes.
4. Spacing — 2–2.5 feet apart for mass plantings; 2.5–3 feet for individual accent plants.
5. Water basin — build a 3–4 inch soil ring around each plant to direct water to roots during establishment.
6. Mulch — apply 2–3 inches of bark or gravel mulch to conserve moisture and moderate soil temperature.

Watering New Gold Lantana in Phoenix

First Year Watering Schedule

• Weeks 1–2: Every 1–2 days, deep and slow (20–30 minutes per session)
• Months 1–2: Every 3–4 days
• Months 3–6: Every 7–10 days (every 5–7 days during peak summer)
• After Year 1: Every 10–14 days in summer; every 3–4 weeks in winter

Drip Irrigation

Use 1–2 GPH emitters placed 18–24 inches from the plant center. Water deeply and infrequently to encourage deep root growth. Once established, New Gold Lantana is one of the most drought-efficient flowering plants for Phoenix landscapes — established plants need watering only every 10–14 days in peak summer to maintain healthy blooming.

How fast does New Gold Lantana grow in Phoenix?
Expect 12–18 inches of spread per year in Phoenix. Growth is fastest in spring and fall and slows during peak summer heat, but the plant continues blooming even as temperatures climb into the 110s.

Is New Gold Lantana sterile?
Yes — New Gold is a sterile hybrid that does not produce viable seed. This is actually a major advantage: all the plant's energy goes into flower production rather than fruit, resulting in an exceptionally prolific and nonstop bloom display. It also means there is no invasive spread concern.

What's the difference between New Gold and other Lantana varieties?
New Gold has solid, uniform golden-yellow blooms that don't change color with age, unlike multi-toned varieties like Radiation (orange-red and yellow) or Dallas Red (deep red). Its consistent yellow color makes it especially useful as a mass planting where a uniform look is desired. It's also slightly more compact than some other Lantanas at 12–18 inches tall.

Does it attract butterflies?
Yes — despite being sterile, New Gold Lantana produces plenty of nectar and is an excellent butterfly plant for Phoenix gardens. It's particularly attractive to monarch butterflies, swallowtails, and Gulf fritillaries during the blooming season.

Will it survive Phoenix's summer heat?
Absolutely. Lantana thrives in Phoenix's extreme summer heat and actually blooms more intensely as temperatures rise. New Gold is one of the few flowering groundcovers that looks its best in July and August when most other plants go dormant or decline.
