Seasonal Flowers in Thailand: What Is at Its Best, Month by Month

If you are trying to work out which seasonal flowers in Thailand are at their best this month, the short answer is that the tropics do not follow the four-season calendar you may have grown up with. Some flowers here bloom almost all year, a few have a clear window, and a good number of the stems in a Bangkok bouquet were never grown in Thailand at all. This guide sorts all three groups, month by month, so you can choose what to buy now and what to leave for later.

We are a Bangkok studio, so the examples lean towards what lands in a Sukhumvit condo or an Asok office tower. Where a claim comes from a published source we link it; where it comes from how flowers generally behave, we say "usually".

Seasonal flowers in Thailand: three seasons, not four

Thai weather is usually described as three seasons: cool, hot and rainy. The cool season runs roughly from November to February, the hot season from March to May, and the rainy season from June to October. The edges move from year to year, so treat the months as a guide.

For flowers the useful difference is not summer versus winter but cool nights versus hot ones, and dry weeks versus wet ones. Cool nights suit crops from temperate climates, such as roses and chrysanthemums. Heat suits the crops that evolved in it, such as orchids and jasmine. Rain helps water plants such as lotus and hurts open-field crops that rot when wet.

Where Thai flowers actually grow

A Bangkok bouquet draws on at least two growing zones. A 1990s paper from the Food and Agriculture Organization describes growing around Bangkok as suited to orchids, and the cooler north and north-east as suited to temperate flowers. The industry has changed since, but the geography has not: orchids and tropical flowers come from the warm central plains, roses and cool-climate crops from higher ground, which is why our piece on Chiang Mai rose farms is a good companion to this one.

The same paper records that Thailand's cut-flower exports in 1993 to 1994 were almost entirely orchids: the flower Thailand grows best is not the rose.

Flowers that ignore the calendar

Two flowers are at close to the same quality in every month:

• Moth orchids. The Royal Horticultural Society describes phalaenopsis as long-lasting and able to bloom at any time of year. A potted phalaenopsis plant is the closest thing Bangkok has to an all-season gift.
• Jasmine. The Missouri Botanical Garden lists Arabian jasmine as flowering year-round in its native range, which includes Southeast Asia. Jasmine garlands are always makeable; they are simply in more demand around certain dates.

Cool season, November to February: roses, chrysanthemum and highland crops

This is the best stretch of the year for buying flowers in Bangkok, and also the busiest. The air is drier, mornings are cooler, and the roses and mums that struggle in March heat hold their shape for longer in your vase. It also contains Loy Krathong, New Year and Valentine's Day, so demand is high from mid-November.

Roses

Cool nights in the northern highlands suit rose growing, and this is when a Bangkok rose order is easiest to fulfil with Thai-grown stems. You will still find imports in the mix, and our guide to imported and Thai roses explains why you should ask about the specific bouquet instead of trusting a label.

A cool-season rose is also the easiest to look after at home. The floral-design instructor in this Purdue Q&A puts rose vase life at five to seven days and advises topping up the water daily, changing it with flower food every two to three days and re-cutting the stems. That advice is written for a temperate kitchen, and a Bangkok condo is closer to those conditions in December than in April.

Our rose bouquets come in red, pink, white-pink and orange, and in sizes from 5 to 500 stems. The 20-stem bouquet is ฿3,299 and the 50-stem bouquet is ฿5,999. Those prices are the same for every colour at a given size, and the page always shows the current figure.

Chrysanthemum and carnation

The cut chrysanthemums sold as pom pom mums are among the longest-lasting stems you can buy. The same Purdue source says carnations, daisies and pom pom mums can last up to two weeks, against three to four days for tulips and daffodils. For a bouquet that must survive a long weekend in an empty flat, this family is the practical answer. Our gerbera, carnation and mums range sits alongside the rest of our flowers by type.

Sunflowers

Sunflowers have a real Thai season. The Tourism Authority of Thailand's blooming calendar places the sunflower fields of Lopburi and Saraburi in November to January, which is also when cut stems are easiest to find in good condition. The Bangkok Post notes that market vendors offer sunflowers as an alternative to roses at Valentine's. A sunflower bouquet suits someone you know well enough to be playful with, but not well enough for a dozen red roses.

Highland and festival blooms

The Tourism Authority of Thailand lists the Chiang Mai Flower Festival among its February highlights, and its blooming calendar places Thai cherry blossoms on the Chiang Mai and Chiang Rai hills in January and February. Those are places to visit, not stems to order.

Hot season, March to May: orchids, lotus and what wilts

From March the city gets hot quickly, and the flowers that suit it become obvious. The ones that do badly are open-field crops and anything with a thin, soft petal. Tellingly, the only March flowers the TAT calendar lists for Bangkok are the yellow trumpet trees in Chatuchak Park, not anything for a vase.

Orchids are the safe hot-season choice

If you can only buy one thing in April, make it an orchid. Orchids are tropical plants that usually cope with a warm room better than a rose does, though two published studies show that handling still matters. A Thai-authored study in PubMed Central kept cut Dendrobium at 13C and recorded about 28 days of life under controlled atmosphere, about 18 days in modified-atmosphere packaging and about 12 days in normal atmosphere. Another, on the Thai cut flower Vanda 'Sansai Blue', found that ethylene exposure reduced vase life and faded colour.

Read those as a warning about storage, not a promise about any particular stem. Cold and clean air matter more than the month: a florist who keeps orchids in a cool room away from ripening fruit will give you more days than one who leaves them on a hot pavement. Thai orchids are in season every month, so the choice is about variety, not timing. Our orchid collection includes mokara, black orchid and orchid-wall designs, and a potted dendrobium sits in the plants range.

Lotus and the water flowers

Lotus is the flower people picture when they think of Thailand, and anyone searching for lotus season Thailand should know the answer depends on where you look. The TAT blooming calendar lists red lotus at Bang Len in Nakhon Pathom, the site nearest Bangkok, from July to December, with other lakes at Phatthalung from February to May and Udon Thani from December to February. Near the capital, the best of it begins with the rains and runs into the cool season.

Lotus buds are sold in Bangkok in any month. National Geographic describes Pak Khlong Talat as open round the clock and best in the cool air after midnight, when boats on the Chao Phraya bring pink and white lotus. Lotus is an offering flower and fragile in a hot room, so we would not send it to an office.

Songkran in the hot season

Songkran falls in mid-April, when UNESCO notes it marks the sun's passage into Aries, with pouring water and honouring elders central to it. The Bangkok Post says phuang malai garlands, commonly made of jasmine, marigolds and roses, are presented to elders at Songkran. A jasmine garland is therefore the right flower for the date; our Songkran occasion page and the guide to Songkran flower delivery in Bangkok cover the practicalities.

What wilts

Roses, hydrangea and any open-faced bloom lose water fast on a hot day. Put the bouquet straight into water and keep it out of direct sun; our guide to making roses last in the Bangkok heat goes through it step by step. If the gift must be roses in April, send a smaller bouquet, which is quicker to get into water.

Rainy season, June to October: the humid months and imports

The rainy season is hot and humid, with afternoon storms that bring an hour or two of heavy rain. For rainy season flowers the issues are mould, bruised petals and delivery logistics.

What the rain changes

High humidity encourages fungal growth on open flowers, and heavy rain damages crops grown in fields without cover. Indoors, the rainy months make vase hygiene matter more: a Cornell study of vase water found bacteria growing more varied over a week, a general finding rather than a Thai one, but a warm, damp kitchen in August is where to act on it with the routine in how to clean a flower vase.

For delivery, rain is a planning matter, not a quality one. A hand-tied bouquet in a matte black wrap with black mesh is protected in transit; allow extra time in the evening, when a storm can stop traffic around Asok and Sathorn. Our delivery page explains how orders are handled, and no exact arrival time is promised.

Imports fill gaps

Some flowers cannot be grown in Thailand at reasonable cost in any season. Tulips are the clearest case: National Geographic states that the Netherlands produces about 90 percent of the world's tulips. Peonies are similar, and the RHS describes their flowering as a brief, keenly anticipated spell in late spring to early summer in a temperate garden. A peony or tulip in a Bangkok shop in September is a cold-chain flower from elsewhere.

That does not make them poor choices. It means their "season" is set by the supplier's cold storage, not the weather outside, so if you want a peony bouquet or tulips, ask what is available that week.

One note on tulips if you share a home with pets: the ASPCA lists tulips as toxic to cats, dogs and horses, with the highest concentration of the toxin in the bulb. The same body lists roses as non-toxic. If you are unsure about a specific flower and a pet, ask your vet before the flowers arrive.

Thai-grown versus imported: what changes month to month

Origin tells you how far a flower has travelled, and little else on its own. Quality depends on the variety, the stage of opening, the storage and the handling.

Group	Usual source	What changes through the year
Orchids, jasmine, marigold, lotus	Thailand	Quality and price vary by weather; supply is steady
Roses, chrysanthemum, carnation	Thailand and imports	Thai supply is easier in the cool season; ask about the batch
Sunflowers	Usually Thailand	Fields flower from November to January
Tulips, peonies	Imported	Supply follows the supplier's cold chain, not the Thai weather
Hydrangea	Mixed	Ask what is in the studio that week

That table is a general guide; we apply no published rule that switches from Thai roses to imports in a given month. Useful questions for any florist are which flowers are Thai-grown, how they have been stored, and what will replace one that is unavailable. You do not need a farm name, just a straight answer; our article on direct-from-farm sourcing explains how we think about it.

Festival flowers: jasmine, marigold, lotus and the calendar

Thai festivals decide the market more than the weather does. Four dates matter most to a buyer of seasonal flowers in Thailand.

Songkran, 13 to 15 April

The Britannica entry on Songkran gives the dates as around 13 to 15 April, with water sprinkled on Buddha statues, alms given to monks and elders honoured. Flowers appear as garlands and offerings, so order a garland early.

Mother's Day, 12 August

The Thailand Foundation states that Thai Mother's Day is 12 August, set in 1976 for Queen Sirikit's birthday, with jasmine as its flower for purity and enduring love. It is the date jasmine is bought for, in the middle of the rainy season. Our Mother's Day collection and the guide to Thai Mother's Day flowers and jasmine go into the gift choices.

Loy Krathong, usually November

The Thailand Foundation's Loy Krathong guide places the festival on the full-moon night of the twelfth Thai lunar month, usually in November, with krathong as offerings of gratitude to the water goddess. Krathong are usually built on banana leaf with marigold and lotus petals. If you are making or buying one, read our Loy Krathong flowers guide first, since it covers what floats and what should not go in the water.

Valentine's Day, 14 February

This is the date when rose demand is most visible. The Bangkok Post reports that Pak Khlong Talat gets busier at Valentine's, with rose bouquets as the best seller. Order days ahead, not hours, and see the Valentine's page for what we offer.

A month-by-month table for bouquet buyers

This table pulls the guide to Thai flowers by season together. "At its best" means the flowers easiest to buy in good condition in Bangkok that month, not a ranking of everything that exists.

Month	Season	At its best	Calendar notes	Buying note
January	Cool	Roses, chrysanthemum, sunflowers	Thai cherry blossoms in the north (TAT)	Best month for long vase life indoors
February	Cool	Roses, sunflowers, carnations	Valentine's Day on 14 Feb; Chiang Mai Flower Festival	Order rose bouquets days ahead
March	Hot	Orchids, jasmine	Yellow trumpet trees in Bangkok parks (TAT)	Switch to smaller, tighter bouquets
April	Hot	Orchids, jasmine garlands	Songkran, 13 to 15 April	Keep flowers out of the midday sun
May	Hot	Orchids, potted phalaenopsis	Start of the rains	Orchids over roses for gifts
June	Rainy	Orchids, jasmine, marigold	Candle flowers in the north-east (TAT)	Plan around afternoon storms
July	Rainy	Orchids, lotus buds	Red lotus at Nakhon Pathom begins (TAT)	Lotus is an offering, not an office gift
August	Rainy	Jasmine, white-pink roses	Mother's Day, 12 August	Order jasmine early in the week
September	Rainy	Orchids, roses with care	Rains at their heaviest	Clean vase water often in humid weather
October	Rainy, easing	Orchids, mums, roses with care	Rains begin to ease	Plan ahead for the cool-season rush
November	Cool	Roses, marigold, mums	Loy Krathong, usually November	Marigold for krathong, roses for gifts
December	Cool	Roses, sunflowers, mums	Christmas and New Year	Book larger sizes in advance

Start with the occasion, not the month: a festival takes the festival's flower; a birthday takes the "at its best" column. The home matters too, since a sunny balcony with no air-conditioning is a very different December from a sealed condo. For the December table in particular, see Christmas party flowers in Bangkok.

How seasons affect price and availability

Demand changes the market more than weather does, and the calendar of demand is predictable.

Where prices move

The peaks are the festival dates above and the New Year period; the Bangkok Post describes Pak Khlong Talat getting busier around Valentine's. For the buyer the effect is less about price and more about stock: popular sizes sell out and the same-day cut-off matters more.

FlowerRova's rose prices are listed by stem count, with the same price for every colour at a size, and we do not publish month-by-month changes, so look at the page on the day. The 10-stem bouquet is ฿2,399, the 30-stem ฿3,999 and the 100-stem ฿8,999.

Lead times you can plan around

The lead times are fixed and do not change with the season. Bouquets of up to 40 roses can go the same day if you order by 9 pm Bangkok time. Fifty roses need an order by 7 pm. Seventy and 100 roses need 24 hours' notice, 200 roses need 48 hours, and 500 roses need 48 to 72 hours. We promise no exact arrival time. In festival weeks, order at the early end of those windows.

Worked example: a late-January birthday

Say a friend's birthday falls on a Friday in late January and she lives in a serviced apartment in Ari. January is cool, so roses will hold. You choose 20 pink roses at ฿3,299. Twenty stems qualify for same-day delivery if ordered by 9 pm, so Friday itself works, but ordering on Thursday evening takes the pressure off. You send them to the front desk, having checked she is happy to collect there. The card might read: "Happy birthday. The pink ones are because you said you were tired of red."

Worked example: a May client thank-you

A consultant wants to thank a client at an office tower on Sathorn in May, when the city is at its hottest. Cut roses would stand on a reception counter in heat, so she chooses a potted phalaenopsis from our plants collection instead and checks the page for the current price. The reception team can keep it in the cool lobby until the client collects it. Her card reads: "Thank you for a good year. This one will last longer than the project did."

When seasonal does not matter

Seasonality should not rule your gift. If the person loves red roses, send red roses in April and tell them to put the vase in the coolest room. Equally, do not buy a flower because it is in season if the person dislikes it: someone sensitive to strong scents will not enjoy jasmine just because it is August, and a short message asking what they like costs nothing.

A short checklist before you order

1. Is the date a Thai festival? If so, buy the festival flower early.
2. Will the bouquet sit in a hot room, or an air-conditioned one?
3. Is anyone in the home allergic, or are there pets? The tulip warning applies in every month.
4. Do you need a particular imported flower such as a peony or tulip? Ask what is available that week.
5. Does the order fall within the lead times above?

Frequently asked questions

What flowers grow in Thailand year-round?

Orchids, jasmine, marigold and many tropical foliage plants grow here in every month. The Royal Horticultural Society notes that moth orchids can bloom at any time of year, and the Missouri Botanical Garden says Arabian jasmine flowers year-round in its native range. Roses and chrysanthemums are available all year, but Thai supply is easier in the cool season.

When is the best month to buy flowers in Bangkok?

For vase life, the cool months from November to February are easiest, because indoor temperatures and humidity are lower. For orchids and jasmine, any month works. For a festival gift, choose by date: Songkran in April, Mother's Day in August, Loy Krathong in November and Valentine's Day in February each have their own flower.

Are the flowers in Bangkok bouquets Thai-grown or imported?

Both. Orchids, jasmine, marigold and lotus are Thai. Roses and chrysanthemums come from Thai farms and from imports depending on availability. Tulips and peonies are cool-climate crops, so Bangkok supply is usually imported. We do not apply a month-by-month rule, so ask about the bouquet you want.

When is lotus season in Thailand?

It depends on the site. The Tourism Authority of Thailand's blooming calendar lists red lotus at Nakhon Pathom, the closest viewing to Bangkok, from July to December, with other lakes in flower from December to May. Lotus buds are sold in Bangkok in any month, especially at Pak Khlong Talat, but they suit temple offerings better than office gifts.

Do rainy-season flowers cost more?

Not because of rain alone. Price follows demand: Valentine's Day, Mother's Day on 12 August and the New Year period are the busy dates. Our rose prices are listed by stem count, the same for every colour at a size, with no published month-by-month schedule, so check the page on the day you order.

Which flowers last longest in Thailand's heat?

Orchids and chrysanthemum-family flowers such as pom pom mums and carnations. A Purdue floral-design instructor gives up to two weeks for carnations, daisies and pom pom mums, against five to seven days for roses. Keep any bouquet out of direct sun, change the water, and ask us on LINE or WhatsApp for a recommendation for a specific room.
