Lavender in Florida: Which Varieties Survive Zone 9–11 Heat (And Which to Avoid)
Most Florida lavender dies by August—but these 3 varieties survive Zone 9–11 heat. Here’s why English lavender fails and which ones actually thrive.
Yes, you can grow lavender in Florida—but the lavender most people reach for at the garden center will be dead before Labor Day. English lavender, the classic fragrant staple sold everywhere from Home Depot to Trader Joe’s, tops out at USDA Zone 8. Plant it in Central or South Florida and Florida’s summer will kill it within weeks.
The good news: three varieties handle Florida’s specific combination of heat, humidity, and summer monsoon rains. Get the variety right and set up drainage correctly, and lavender is genuinely viable across most of the state—though it looks and behaves differently here than in a California or English garden. Here’s what to know before you plant.
Why Lavender Usually Dies in Florida
Blame humidity, not heat. Lavender evolved on the rocky, free-draining hillsides of the Mediterranean, where summer is hot and bone dry. Florida summers are the opposite: temperatures top 90°F while the state receives 50 or more inches of rain between June and September. That combination—warm, saturated soil—is exactly what soil-borne fungi need to kill lavender roots.
According to UF/IFAS Extension, “in areas of high humidity, root rot due to fungus infection can be a problem” for lavender. The mechanism is straightforward: lavender roots need oxygen in the soil pore spaces. When soil stays wet for days at a time, those pore spaces fill with water, oxygen is cut off, and fungal pathogens like Pythium and Phytophthora consume the roots within weeks. The plant wilts, turns gray, and collapses—and most gardeners blame the heat.
This is why the single most important factor in growing lavender in Florida has nothing to do with the plant itself. It’s your drainage setup.
Florida Zones: Where Lavender Is and Isn’t Realistic
Florida spans USDA Zones 8b through 11b, and lavender success varies significantly by region. For a full breakdown of what grows when across the state, see our Florida gardening guide.
- North Florida and Panhandle (Zones 8b–9a): The most lavender-friendly region. Winters are cool enough for established plants to reset, and summers—while still humid—are shorter. Most varieties that work in Zone 9 will perform well here.
- Central Florida (Zones 9b–10a): Survivable with correct variety selection and excellent drainage. Fall planting is essential to establish roots before the brutal June–August period.
- South Florida (Zones 10b–11b): The most challenging region. Open-ground lavender rarely survives long-term. Containers with a fast-draining mix, moved to covered shelter during heavy rain, give the best odds.
The Three Varieties That Work in Florida
These varieties are recommended by UF/IFAS Extension specifically for Florida’s conditions and confirmed through zone 9 trials.
| Variety | Species | Zones | Best For | Key Advantage |
|---|---|---|---|---|
| Phenomenal | L. × intermedia | 5–9 | North + Central FL | Strongest humidity and root rot resistance of any lavender; proven in hot, humid climates |
| Spanish lavender | L. stoechas | 8–11 | All Florida zones | Tolerates higher moisture than other species; widest zone range; distinctive pineapple blooms |
| Goodwin Creek Grey | L. × ginginsii | 8–11 | North + Central FL | Exceptional heat and drought tolerance; compact grower at 2–3 feet; silvery foliage year-round |
Phenomenal (Lavandula × intermedia) is the top pick for North and Central Florida. It was specifically developed for heat and humidity tolerance—a hybrid that outperforms both parent species in warm, wet conditions. UF/IFAS Extension Pasco County lists it as a go-to variety for hot climates, and it’s the lavender most consistently recommended by growers in humid zone 9 climates. It grows 2–4 feet tall and blooms from late May into July, which—crucially—means most of its flowering happens before the worst of the summer rain season.
Spanish lavender (Lavandula stoechas) has the widest tolerance range and is UF/IFAS’s top recommendation specifically for Central Florida. Its compact growth habit (18–24 inches) and higher moisture tolerance make it more forgiving than other species. The distinctive flowers—purple spikes topped with rabbit-ear bracts—also make it the most visually striking option for Florida gardens. Note that it’s not ideal for cooking or fragrance use compared to English lavender.
Goodwin Creek Grey is worth considering if you want a more drought-adapted plant once established. It handles heat well and the silvery-grey foliage looks attractive even when not in bloom. Like Phenomenal, it works best in North and Central Florida rather than the humid south of the state.

English Lavender: Why to Avoid It in Florida
English lavender (Lavandula angustifolia) is cold-hardy to Zone 5 but struggles above Zone 8. In Central and South Florida, the combination of extreme summer humidity and heat is too much—UF/IFAS Extension describes it as “the most difficult to grow in Central Florida due to the high temperatures and humidity in the summer season.” If you find it at a local garden center, it was likely shipped from a national supplier without regard for local conditions. It will look fine in spring and collapse by July.
Soil and Drainage: The Setup That Determines Everything
Get drainage right and half the battle is won. Here’s how to set up lavender for survival in Florida’s conditions:
Raise the planting area. Whether you’re using a raised bed or mounding soil in a garden bed, getting the root zone 6–12 inches above the surrounding grade dramatically reduces waterlogging risk during Florida’s summer downpours.
Stop missing your zone's planting windows.

Amend soil with grit. Lavender wants fast-draining soil with a pH of 6.5–7.5. Mix native soil with 30–40% coarse sand, perlite, or fine gravel to create a mix that sheds water quickly.
Skip the bark mulch. UF/IFAS Extension specifically warns against organic mulches around lavender in humid climates—they retain moisture at the crown and accelerate fungal rot. Use gravel or crushed rock as a mulch instead. A 1–2 inch layer of pea gravel around the base keeps the crown dry, reflects heat from the soil surface, and discourages rot.
Space for airflow. Crowded plants trap humidity between them. Give lavender at least 18–24 inches between plants to allow air to move through, which helps dry foliage after rain.
When to Plant Lavender in Florida
Timing is the other major variable. See our Florida planting calendar for full zone-by-zone timing, but the core rules for lavender are:
- Best window: October–November. Fall planting gives roots 6–8 months to establish before the summer monsoon season hits. An established lavender plant handles Florida summers far better than a newly planted one.
- Second option: February–March. Spring planting in Central Florida can work, but it gives the plant a shorter establishment window before summer arrives. Water regularly (but not excessively) during the first 8 weeks.
- Never plant in summer (June–August). New transplants can’t withstand Florida’s combination of monsoon rains and heat. Root rot will take hold before establishment is complete.
Frequently Asked Questions
Can lavender survive a Florida summer?
Established plants of Florida-appropriate varieties—Phenomenal, Spanish, or Goodwin Creek Grey—can survive Florida summers if drainage is excellent. Expect reduced growth and possibly some dieback during the wettest weeks of July and August. This is normal semi-dormancy, not death. Cut back dead stems in September once the rain eases.
Can I grow lavender in South Florida (Zones 10b–11)?
Open-ground lavender is very difficult in South Florida long-term. Your best option is containers: use a fast-draining cactus/succulent mix, move pots to a covered patio or overhang during the heaviest summer rains, and choose Spanish lavender as your variety. Treat it as a seasonal plant and replace it if it declines after two or three summers.
Does lavender come back every year in Florida?
With the right variety and drainage, yes—lavender is perennial in Florida. Phenomenal and Spanish lavender are both rated to Zone 8–11 and will regrow each spring. The caveat is that plants in Central and South Florida may decline after 3–5 years as cumulative heat and humidity stress takes a toll. Most Florida growers treat lavender as a medium-term perennial and replace plants as needed.
