The Best Flowers for Florida Heat and Humidity (and How to Help Them Last)

Quick answer: The cut flowers that hold up best in Florida heat and humidity are orchids, anthurium, alstroemeria, chrysanthemums, carnations, protea, ginger, heliconia and lisianthus. Roses also do well when kept in cool, fresh water. Delicate flowers such as hydrangeas, sweet peas, tulips and peonies are beautiful but need more care in warm conditions.

South Florida's climate is wonderful for people and tough on cut flowers. Warm rooms speed up how quickly flowers open, drink water and fade. Choosing the right blooms, and placing them well, can add days to the life of an arrangement.

Why Heat and Humidity Affect Cut Flowers

Cut flowers are living plant tissue without roots. In warm temperatures they:

• Drink and lose water faster, so vases run low quickly.
• Open faster, which shortens their peak display time.
• Grow bacteria faster in the vase water, which can clog stems.

Humidity itself is less of a problem indoors, but moving flowers from a hot car into an air-conditioned room, or leaving them near a sunny window, stresses them. The goal is steady, cool conditions and clean water.

Flowers That Thrive in South Florida

Orchids

Phalaenopsis, cymbidium, dendrobium and oncidium orchids are naturally suited to warm climates. Cut orchids can last well over a week, and potted phalaenopsis orchids can bloom for weeks with minimal care.

Anthurium

Glossy, sculptural and tropical, anthurium is one of the longest-lasting cut flowers. It rarely wilts in warm rooms and suits modern, minimal designs.

Alstroemeria

Also called Peruvian lily, alstroemeria is famously long-lasting, often one to two weeks, and new buds keep opening along each stem.

Chrysanthemums and carnations

Often overlooked, these are among the hardiest cut flowers available. Modern varieties, such as spider mums, button mums and ruffled carnations, look elegant in a designer arrangement.

Protea and leucadendron

These sturdy South African flowers are built for heat and dry conditions. They bring texture and dramatic shape, and many even dry beautifully.

Tropicals: ginger, heliconia and bird of paradise

Bold tropical stems love warm weather and make a statement in larger arrangements, especially for events and lobbies.

Lisianthus

Lisianthus looks delicate, almost like a rose, but holds up surprisingly well and keeps opening buds over several days.

Roses

Roses do well in Florida when they are properly conditioned and kept in fresh, cool water. Choose fully hydrated, freshly processed stems from a local florist rather than roses that have sat in a warm store. Browse our rose collection.

Flowers That Need Extra Care in the Heat

These flowers are worth it, but treat them gently:

• Hydrangeas: Big, cloud-like, thirsty heads that wilt quickly if they dry out. They often revive with a full submersion in cool water. See our hydrangeas.
• Peonies: Gorgeous but fast to open in warm rooms. Keep them cool to slow them down. See our peonies.
• Tulips: Keep growing in the vase and bend toward light. Use shallow, cool water.
• Sweet peas and garden roses: Fragrant and romantic, with a shorter vase life in heat.
• Gardenias: Bruise easily and brown in warm conditions.

How to Keep Flowers Fresh in Florida

These tips make the biggest difference in a warm climate:

1. Place flowers in the coolest room of the house, away from direct sun, appliances and electronics.
2. Keep them away from AC vents. Constant airflow dries petals out, even though the air is cool.
3. Check the water daily. In warm homes, vases can drop significantly in a day.
4. Change the water every two days and rinse the vase to keep bacteria down.
5. Recut stems at an angle, about half an inch, each time you change the water.
6. Use flower food from the florist. It feeds the blooms and slows bacteria.
7. Never leave flowers in a parked car. Even a short errand in Florida sun can damage them.
8. Move them somewhere cooler at night, if a room gets warm when the AC cycles down.

Florist tip from Anastasiia: "Hydrangeas are my favorite flower, and I won't give them up just because it's hot. If a head starts to droop, don't panic: lay it in a sink of cool water for half an hour. It's like watching a cloud come back to life."

Best Flower Choices by Occasion in Warm Weather

• Long-lasting gift: Orchids, anthurium or a mixed design with alstroemeria and lisianthus
• Romantic: Freshly conditioned roses in a vase, ideally delivered rather than carried
• Sympathy: White orchids, lilies, chrysanthemums and roses, which hold up well in warm homes and services. See our custom sympathy flowers.
• Office or lobby: Tropical stems and orchids, which tolerate long hours of indoor light. Our corporate flowers program uses many of them.
• Outdoor events: Tropicals, protea, orchids and sturdy roses, with delicate flowers kept to shaded areas. See our events page.

Delivery Matters in the Heat

How flowers travel affects how long they last. Same-day local delivery means arrangements spend only a short time in transit, rather than a day or more in a shipping box in a warm truck.

Every Monalli arrangement comes with our 3-day freshness guarantee. Order from our shop, or ask for a heat-friendly design through a custom order.
