The Flowerbulb Business Days: where export and cultivation meet

Following the success of the past three years, the Flowerbulb Business Days will be back in 2026! From 25 to 27 February 2026, 24 flower bulb growers will join forces at various locations in northern Noord-Holland region. These days offer professionals the opportunity to visit each other and view each other's businesses and product ranges.

What can you expect?

Each participating nursery will organise a trade show at its own location. Admire the latest varieties, innovations and trends in the world of flower bulbs. On Wednesday evening, 25 February 2026, a convivial networking evening will be organised during the Flowerbulb Business Event. An excellent opportunity to connect with colleagues from the flower bulb sector.

Tulip cultivation in the Netherlands is in the spotlights for three days during the Tulip Trade Event! From 18 to 20 March 2026, exporters and breeders in the Netherlands are combining their open days. This makes the Tulip Trade Event an expanding and colourful display case for tulip cultivation. Over three days visitors can see the entire assortment in bloom, hear about which new trends and cultivation methods are becoming popular and catch up with their business relations.

We hope to welcome you at our company during this event and make you enthusiastic about our company and our product.

Keukenhof, the best day out among the flowers! There are more than 7 million bulbs in bloom this spring, with a total of 800 varieties of tulips. A unique and unforgettable experience!

Besides the spacious 32 hectares of flowers, you can enjoy the spectacular flower shows, surprising inspirational gardens, unique artwork and wonderful events. Do not miss the Tulpomania exhibition in the Juliana Pavilion.

Keukenhof is also one big party for children. They will have a blast with the treasure hunt, petting farm, maze and the playground.

We have been one of Keukenhof's contributors for many years. You can find our garden near the Beatrix Pavilion.

The Hortus Bulborum is the only museum garden in the world where you can find over 4,000 different tulip, hyacinth, daffodil and other bulbous cultivars, species and varieties in bloom. Nowhere on this globe you will find such a fine selection of old bulbs in one place. Every spring the Hortus transforms into a treasure trove full of dazzling colours, beautiful shapes and overwhelming fragrances at the foot of the picturesque, parish church in Limmen village, near the historic city of Alkmaar.

The collection boasts tulips dating from 1595, the famous ‘Duc van Tol Red and Yellow’; the oldest known cultivar and dozens of other cultivars which were prizes possession as far as back as the Golden Age. But also 17th century daffodils. The most antique daffodils are said to come from around 1601, like ‘Double Campernelle’ and ‘Albus Plenus Odoratus’. Though the Narcissus pseudonarcissus, also known as the 'Lent Lilly', was already found in English gardens in the 1200s. While the oldest fritillary was already described for the first time in 1577, Fritillaria imperialis ‘Prolifera’. And what to think of fragrant double-flowered hyacinths from the 1800s and crocuses.

Fundamental in this garden, however, is the preservation of heirloom bulbs. Many of them have no commercial value for modern mass production whatsoever. The aim is to maintain these cultivars and safeguard them for the future generations. The preservation work of the Hortus Bulborum goes hand in hand with the work of the professional growers to obtain better cultivars for today’s needs. The collection is a second to none pollen bank in the world to the bulb growing sector.

The current collection contains over 2,600 cultivars of tulips (species and varieties), some 130 hyacinths, around 1,100 daffodils, some 110 crocuses and a few dozen of fritillaries. 

The Hortus Bulborum is worth a visit, especially for garden lovers and all those who love rare, heirloom and florist bulbs.

Bloemencorso Bollenstreek: Colourful world heritage

Bloemencorso Bollenstreek, the Flower Parade of the Bulb District is an annual event that has taken place since 1947. During the parade, floats richly decorated in spring bulb flowers travel the 42 km route from Noordwijk to Haarlem. The event attracts almost one million visitors each year.

In 2021 the parade was recognised as Dutch Intangible Cultural Heritiage. This recognition emphasises the cultural importance of the flower parade tradition in The Netherlands.

The 79th edition of Bloemencorso Bollenstreek takes place on Saturday 18th April 2026. The route starts in Noordwijk and finishes in Haarlem passing through villages and towns in the Dune and Bulb district of The Netherlands.

For three days prior to the parade you can watch the art of decorating the floats at JUB Holland in Noordwijkerhout. Hundreds of volunteers are busily attaching the millions of flowers. With luck you may get a chance to give them a hand.

On Friday evening you can view the Bloemencorso Bollenstreek flower parade in a different light. At 21:00 hrs they illuminate the floats with thousands of lamps as they drive through the charming village of Noordwijkerhout. An experience not to be missed.

On Sunday the floats are on show one last time in the historical floral city of Haarlem. Use the opportunity to take perfect pictures surrounded by music and entertainment while enjoying a drink at one of the cafes. At the end of the afternoon they wave the floats a final goodbye.

From 18 April to 22 April 2026,  Anna Paulowna is dedicated to the colours and scents of the 71st edition of the Flower Days. Throughout the event, you can admire over 100 mosaics, moving pieces and decorated streets and bridges.

Mosaics
The mosaics are paintings made on polystyrene, made by sticking pins topped with flower buds into the surface. Every square yard is covered by over 10.000 buds, which gives you a taste of the amount of work that goes into making every single mosaic. Young and old come together during the Flower Days to create the mosaics and display them in their gardens. Take your bicycle, car, or step on board of one of our dedicated buses to see all mosaics. If you collect a list of participators at either our central information point or the information booths you can find along the side of the road during the Flower Days, you can create your own custom route along all the mosaics. Don’t forget that at night the Flower Days are a true spectacle as well, with most mosaics, bridges and streets lit up.

Complete your day with a visit to one of our many expositions, flea markets, workshops or scavenger hunts. Participation and entry are free.

The Dutch Lily Days, which are being organised from 2 to 5 June 2026, are the premiere event to discover the latest trends. A particular focus lies on pollen-free and double-bloomed varieties, and the various participants are looking forward to proudly showing you their innovations. Another important theme is the never-ending search for resistant – and thus more sustainable – lily varieties.

Pollen-free lilies are growing in popularity, with both consumers and florists. Sustainability is and remains another important point. The retail sector keeps setting stricter conditions on the use of crop protection and demands the cleanest possible bulbs and flowers. That presents an interesting challenge for breeders!

Improvement and added value
The global demand for lilies seems to be stabilising. For years, it has been one of the most popular flowers in the world, with a known unique value in many countries. A realistic prediction suggests that the demand is unlikely to grow much more. In the last ten to fifteen years, growth was only achieved by entering new markets, like China and Vietnam. In the existing markets where lilies have been extremely popular for a long time, saturation seems to have been reached, even occasionally a lessening of demand. To keep up the global demand for lilies, we have to search continuously to improve the assortment and add value. Attractive innovations, like the pollen-free and double-bloomed varieties, are supporting that trend.

We are one of the participants of the Dutch Lily Days, and hope to welcome you at our company in June 2026!

During the weekend of January 24th up to and including January 26th, the 40th – and final - edition of flower show 'Westerkoggeflora' will be held. This last edition revolves around Tulips, the art of Koggenland. Besides all of the tulips that are sent by tulip growers from the Koggenland area, the show is decorated with tulip art. The Westerkoggeflora takes place in Sporthal De Koggehal (De Goorn).

The art of tulips

Tulip cultivation and forcing is an art! The weather conditions, the quality of the tulip bulbs, the preparation, and eventually the forcing: it is a trade in itself. Over and over again, and each year is different! And we will show this to the public for one more time at the end of January. At the same time, various artists show their tulip art.

Between all of the art, the tulip growers show us their best tulips and will compete for one more time. Besides tulips, visitors can also admire decorations of lilies, alstroemerias, roses, chrysanths, and several other flower varieties.

Competition between primary schools

By tradition the students from the primary schools in Koggenland have received a pot with tulip bulbs with the assignment to make them flower perfectly. The most beautiful tulips get podium places at the Westerkoggeflora.

Free entry all weekend

We have organised beautiful shows for more than 40 years that brought in visitors from all over the Netherlands to Koggenland. We invite everyone to have a look one more time in the weekend of January 24^th to January 26^th. Because it is the last Westerkoggeflora, the entry to the exhibition will be free to the public for the entire weekend! On Sunday there will be music from Gerard Koedooder.

The Westerkoggeflora will take place from January 24^th to January 26^th, 2020, and is open every day from 10:00 AM. Entry is free.

It all revolves around cooperation. For this reason, KAVB, Rabobank WFO, PPO Lisse, Proeftuin Zwaagdijk, CNB, Clusius College, InHolland, Greenport NHN and Hobabo organise the 'Day of the tulip' for the sixth time. The programme is inspiring and offers something for everyone. The target group consists of bulb growers and other parties in the flower bulb sector. The event will take place on January 24th, 2020 at Proeftuin Zwaagdijk. Multiple presentations and workshops will be given during this day, and there is also time for networking in the lobby.
