The one plant you should never keep on a bedside table if you suffer from hay fever, allergists warn

It starts the same way most spring and summer nights do for people with hay fever.

It’s late. The window is on the latch for a bit of air. You’ve taken your antihistamine. The lights are low, your phone is finally out of reach. And yet your nose has other plans. It prickles, then runs. Your eyes burn. You reach for another tissue and stare across the room.

On the bedside table, in the soft pool of lamplight, sits a graceful vase of flowers. Tall stems, glossy leaves, wide open blooms. You bought them – or someone bought them for you – to make the room feel calmer. More luxurious. More “hotel”. Instead, they may be quietly turning your sleep into an all‑night allergy test.

Allergists will tell you that for most hay fever sufferers there is one plant that has no business living half a metre from your face.

The pretty culprit: why lilies and hay fever do not mix

The plant in question is the lily – particularly the big, showy, heavily scented types you find in bouquets and supermarket bunches.

“If you struggle with hay fever, putting lilies next to your bed is a bit like sleeping beside a mini pollen factory,” one UK allergy specialist told me. “You’re almost guaranteeing a rough night.”

Lilies tick several boxes that make them especially unhelpful if you have allergic rhinitis:

• They release large amounts of visible pollen from prominent stamens.
• Their strong fragrance can irritate already sensitive noses and airways.
• The blooms sit right at breathing level if they’re on a bedside table.

Every time you turn over, adjust your duvet or reach for your water glass, you stir the air around them. Pollen that was sitting calmly on the anthers becomes airborne, drifting onto your pillow, pyjamas and face. By the time you wake up, it’s on your hands and sheets as well.

You do not have to be allergic specifically to lily pollen to feel miserable. For people whose immune systems are already primed to overreact to pollen – grass, birch, weeds – any extra irritant in a small, enclosed space can tip you from “slightly stuffy” to “I can’t breathe through my nose at all”.

Why your bedside table is the worst place for them

If lilies sat in a large, airy hallway, their pollen and perfume would at least have space to disperse. The bedroom is different, and the bedside table makes the problem worse for three simple reasons.

First, distance. When you lie down, your nose and mouth are only a short drift away from the flowers. Pollen does not need to travel across the room – it falls exactly where you sleep.

Second, timing. Allergic inflammation often flares at night and in the early hours of the morning, when your body’s natural cortisol (an anti‑inflammatory hormone) dips. That’s why hay fever sufferers so often wake up more congested than they felt at bedtime. Adding a fresh supply of pollen to that nightly peak is a guaranteed way to amplify symptoms.

Third, contact. Pollen grains from lilies are famously clingy. They stick to skin, hair and fabrics. Brush against the flowers on your way to switch off the lamp, and you can carry that pollen straight onto your pillowcase, where it has hours to irritate your eyes and nose.

It’s not just sniffles. Some people experience headaches, sinus pressure, coughing or a tight chest when they sleep near lilies, especially in small or poorly ventilated rooms. For anyone with asthma on top of hay fever, that combination is even riskier.

“But they’re indoors, how bad can it be?” – the myth about houseplants and pollen

There’s a comforting story many of us tell ourselves: outdoor pollen causes hay fever, indoor plants are harmless. The reality is fussier.

Lilies are insect‑pollinated, not wind‑pollinated like grass or birch. That means their pollen grains are larger and heavier, and they do not travel as far. But in a bedroom, they do not need to. When the source is less than an arm’s length away, “doesn’t travel far” is still plenty.

The other problem is volume. A single lily flower can carry thousands of grains of pollen. A full stem with multiple open blooms concentrates a surprisingly heavy load into one small vase.

A few common mistakes make things worse:

• Cutting stamens late – Many people only snip off the pollen-covered anthers once the flowers are fully open and already shedding. By then, a chunk of the pollen is already on nearby surfaces.
• Shaking or blowing on the flowers – Trying to “clean” pollen off by blowing or tapping the stem simply launches more of it into the air.
• Rearranging them over the bed – Trimming stems, changing water or moving the vase while standing over your duvet helps pollen fall exactly where you’ll be sleeping.

In other words, lilies indoors can absolutely trigger or amplify hay fever symptoms – particularly when they are close to your face, disturbed regularly and left in place for days.

How lilies compare with other bedroom plants

Not all plants are equal when it comes to allergy trouble. Some are relatively neutral by your bed; others, like lilies, are best enjoyed in another room.

Plant type	By‑bedside allergy risk	Why it matters
Lilies (cut flowers)	High	Heavy pollen, strong scent, close contact with face
Foliage houseplants (no obvious flowers)	Low–moderate	Minimal pollen; main risk is dust and mould in soil
Dried bouquets / grasses	Moderate–high	Trap dust, may shed fine particles and old pollen

For most people with hay fever, a plain green plant in a corner of the room is far less of a problem than a fragrant bouquet at arm’s length.

The main exception is dried flower or pampas grass arrangements, which can quietly collect dust, mite droppings and residual outdoor pollen over time. They might not be as dramatically irritating as lilies, but if your hay fever is severe, they’re worth keeping away from the bed as well.

Better choices: bedroom‑friendly plants if you’re allergy‑prone

You do not have to banish all greenery from your bedroom. Many allergists are comfortable with low‑pollen houseplants, as long as you look after them sensibly.

Safer options usually include:

• Non‑flowering (or rarely flowering) foliage plants
  Think snake plant, spider plant, pothos (devil’s ivy), rubber plant, ZZ plant. These produce negligible airborne pollen indoors.

• Orchids and some succulents
  Their flowers release relatively small amounts of pollen, and they tend not to shed it into the air in the same way as lilies or chrysanthemums.

• Plants kept slightly away from the bed
  Position them across the room or near a window, not right by your head.

Simple maintenance also makes a difference:

• Wipe leaves with a damp cloth every week or two to reduce dust.
• Avoid over‑watering; soggy soil encourages mould, which can irritate noses just as much as pollen.
• Remove any dead leaves or flowers promptly, rather than letting them decay in the pot.

If you notice that your nose or chest always feel worse after watering or repotting, or after you bring a particular plant into the room, pay attention. Your body is giving you useful data.

A small bedtime checklist to give your nose a break

If you live with hay fever and want to sleep better through the worst months, lilies on the bedside table are an easy “no”. A few other quiet tweaks can help as well:

• Keep all cut flowers, especially lilies, chrysanthemums and heavily scented blooms, out of the bedroom.
• Change your pillowcase more often during peak pollen season, even if the rest of the bedding looks clean.
• Shower or at least rinse your face and hair before bed if you’ve been outside during the day.
• Use a cool, gentle fan or air purifier rather than sleeping with the window wide open on high pollen days.
• Keep pets off the bed where possible; they bring outdoor pollen in on their fur.

None of this will cure hay fever. But reducing the number of irritants – especially ones sitting right next to your face for eight hours – can mean fewer wake‑ups, less morning congestion and a little more energy to face the day.

“Think of it as allergy budgeting,” another allergist said. “You can’t get rid of every trigger, but you can choose not to spend your limited tolerance on a vase of lilies by your pillow.”

If you love lilies, enjoy them in the hallway, the sitting room or on the dining table. Let them be the centrepiece of a meal, not the reason you wake up for the third time at 3 a.m. wondering where all this sneezing is coming from.

FAQ:

• Are lilies the only flowers I should avoid if I have hay fever?
  No. Other strongly scented, pollen‑heavy flowers such as chrysanthemums, asters and some types of daisies can also be unhelpful, especially in small bedrooms. Lilies are singled out because they combine heavy pollen with very strong perfume and are often kept close to the bed.
  
• If I cut the stamens off my lilies, are they safe in the bedroom?
  Snipping the stamens early – before the anthers burst open – can reduce pollen spread, but it rarely removes the problem completely. Some pollen will already have been released, and the scent may still irritate sensitive noses. For hay fever sufferers, it is usually safer to keep them out of the bedroom altogether.
  
• Can ordinary houseplants make hay fever worse?
  Most common foliage plants release very little pollen indoors. When problems do arise, they are often due to dust on leaves or mould in damp soil rather than the plant itself. Keeping plants clean, not over‑watering, and avoiding very large numbers of plants in a small bedroom can limit this.
  
• Is it better to have no plants in the bedroom if my allergies are bad?
  If your hay fever or asthma is severe, some specialists do suggest keeping the bedroom as “clean” as possible – minimal fabrics, minimal dust traps, and no plants. For milder symptoms, carefully chosen low‑pollen plants placed away from the bed are often fine. It’s worth discussing your specific situation with your GP or an allergy specialist.
  
• Does this advice replace seeing a doctor about my hay fever?
  No. Avoiding lilies by the bed is a simple, practical step, but it is not a treatment. Persistent or severe symptoms, night‑time wheeze, or any breathing difficulty should always be assessed by a healthcare professional.
