Spring in Holland is ideal with glorious sunshine and nice temperatures. Unfortunately, of course, sometimes it can be rainy. During the Tulip Festival, there are great activities to do even on rainy days and you can still enjoy the tulips in Holland.. A big advantage of visiting the tulips during a rainy day is that it is usually a lot quieter in Keukenhof Gardens and at the tulip fields. Read our tips below should it unexpectedly be a rainy day during your visit to the tulips
Tulips are one of the most iconic flowers, gracing gardens and bringing color to landscapes across the world each spring. But observant gardeners may notice these flowers behaving a bit peculiarly during rainy weather. The vibrant tulip blooms that opened widely under sunny skies suddenly begin closing up their petals when clouds roll in. So why do tulips close when it rains?
As an avid gardener and tulip enthusiast myself, I’ve long been fascinated by this phenomenon. After years of pondering this floral mystery and doing some research, I’ve uncovered the reasons behind this peculiar tulip behavior in wet conditions.
Protecting Pollen and Reproductive Parts
One of the primary reasons tulips close up in rain is to shield their reproductive parts. Inside each tulip bloom is the pistil and stamens containing the pollen and nectar. When open exposure to rain can damage or wash away this pollen.
By closing their petals, tulips form a protective barrier around these essential reproductive organs. This ensures the pollen stays viable and undamaged by raindrops for future pollination when the sun returns. Even during spring showers, tulips take measures to keep pollination possible.
Preventing Petal Damage
Heavy rain and wind can also batter and tear delicate tulip petals. Their thin, colorful petals are more vulnerable to such unfavorable conditions when fully opened.
When tulips close up their blooms it forms a buffered enclosure that shelters the petals from damage by storms. After the clouds pass they can reopen intact, showing no ill effects from this protective strategy.
Conserving Energy in Adverse Weather
On cold and cloudy rainy days, tulips receive less warmth and sunlight from their environment. Researchers believe closed tulips may conserve energy much like they do at night.
With limited heat to absorb and minimal sunlight for photosynthesis, closing petals redirects the plant’s resources to endure the weather. This allows tulips to continue thriving when sunshine returns.
Regulating Flower Temperature
Interestingly, some research suggests closed tulips may help regulate interior flower temperatures. The black centers of tulip blooms absorb heat from the sun’s rays.
When closed up, the envelope of petals provides insulation that retains this warmth in chillier weather. This temperature control may also make closed blooms more inviting shelters for pollinators during rain.
Following Circadian Rhythms
Tulips don’t just close up from external cues like rain. Their opening and closing also follows circadian rhythms or an internal 24-hour clock.
So even in clear weather, tulips can continue closing blossoms overnight according to these rhythms. But rain provides added reason to keep petals shut when there are no pollinators about anyway.
Cues for Seeking Shelter
Bees and other pollinators also dislike wet conditions. As tulips start closing their petals due to rain, it can serve as a signal for these pollinators to similarly seek shelter nearby.
The insects may then take cover inside partially closed tulips or other dry locations until the rain ceases. This synchronization benefits both plants and pollinators.
An Adaptive Rain Response
Not all tulips close up identically in the rain. Some varieties are highly sensitive, shutting petals at the first drop of rain. Others may continue displaying open blooms longer into a light shower.
But most tulips have adapted some sort of protective rain response. Through evolution, this trait of closing blossoms in wet conditions benefited survival and reproduction.
Temporary Protection Only
In most cases, tulips only keep their flowers closed temporarily during rain or storms. As soon as the clouds clear and sunlight emerges again, they will reopen to benefit from the return of ideal conditions.
Understanding why tulips close in the rain reveals the ingenious ways they cope with less than ideal weather. A little short-term closure is a small price to pay for ensuring healthy, vibrant spring blooms. When the skies clear after spring showers, tulips again unfurl their petals to continue their spectacular floral display.
So next time you see your garden tulips closed up during spring rains, remember it’s just a brief intermission. These fascinating flowers are simply protecting their pollen and themselves until the sun comes out once more.
Photographing tulips with raindrops
If you’re in Keukenhof and it’s raining, we definitely recommend you try this. Did you know that it can be very beautiful to photograph tulips with raindrops on them? Tulips with raindrops on them can capture a unique moment that is not always easy to find. It can produce a unique and beautiful photo! Play around with exposure, depth of field, and composition. Photographing tulips with raindrops on them can result in beautiful and unique photos!
In your travel luggage, consider a rain jacket and or umbrella
If you travel to the Netherlands then it is always handy to bring a rain outfit. This can be a rain jacket or a rain poncho. An umbrella is also a handy item to have with you should it suddenly start to rain. At Keukenhof Gardens, rain ponchos and umbrellas are also on sale at the souvenir shops.

FAQ
Do tulips close up in the rain?
Tulip flowers open and close in response to heat and light. When tulip petals fold in at night, or on a rainy day, the pollen stays dry and reproductive parts are protected. When they open the next morning, the pollen is ready to attach to the bodies of hungry insects.
Is too much rain bad for tulips?
Rainwater is also not a problem as long as you have adequate drainage — several holes at the bottom of the pot and some crocs or grit at the base. If you think about it, the tulips that are planted in the ground get rained on just as much but they are fine.
What temperature should I cover my tulips at?
If you have a spring snow or freeze, what will happen to your tulips? The plants should be fine at 20 or 25 °F. Below those temperatures, any frozen part of the plant will be damaged and not able to make food for next year’s bulb.
Why do tulips open and close?
If you have ever watched a tulip in the morning, you may have noticed that when the sun rises and light strikes its petals, they open up again. This is because tulips are photoperiodic plants, meaning that their blooms respond to changes in day length with respect to heat and light.
Do tulips open and close at night?
Tulips will close their petals during the night and open in the morning. It is something you shouldn’t worry about as it is their natural way of resting at night. Tulips opening and closing depend primarily upon the light and temperature they receive. This nature is called nyctinasty.
Do tulips lose water at night?
Tulips will close their leaf pores at night, so there will be no transpiration or evaporation. Moreover, photosynthesis stops due to a lack of sunlight. This means your plant won’t lose water. So, the plant cells remain turgid, and no water is required.
Do tulips have nyctinasty behavior?
Tulips do have nyctinasty behavior as they close during the night. But they are also called photonastic plants. Tulips tend to close according to the light movements. Thus, when they do not get light, the tulip petals will close. Heliotropic movement benefits the tulips in receiving the maximum amount of warmth and energy from the sun.
Why do tulips fold together?
This is because tulips are photoperiodic plants, meaning that their blooms respond to changes in day length with respect to heat and light. When night falls and darkness engulfs the plant’s environment, their petals fold together like an umbrella to protect themselves from potential dangers such as moisture droplets or insects.
Do morning glory flowers open or close when it rains?
Morning Glory petals will be open during nice days, but close tightly when rain comes rolling in. Many plants such as dandelions, clover, and chickweed respond similarly. Leaves on many deciduous trees and shrubs will flip over before it rains.
