Key takeaways
- Paperwhites need no chilling, so you can pot them and bring them straight indoors
- They usually flower 4-6 weeks after potting, a little slower in a cool room
- Pot from late October to mid-November for flowers at Christmas
- Keep the water just below the bulbs, never touching them, or they rot
- Grow them cool and bright at 10-15°C to stop tall, floppy stems
- Pot a new bowl every two weeks for flowers right through winter
Paperwhites are the easiest bulbs to bring into flower for Christmas. Pot them up, add water, and about six weeks later you have clusters of small white, strongly scented flowers. No fridge, no dark cupboard and no waiting for the cold.
The only real trick is stopping them growing tall and flopping over. This guide covers choosing bulbs, potting them in gravel, getting the water level right and timing them for the big day. If you want to force hyacinths, crocus or other bulbs as well, our guide to forcing bulbs for indoor flowers covers the ones that need a cold spell first.
Why paperwhites don’t need chilling
Paperwhites come from the warm Mediterranean, so they don’t need a winter to trigger flowering. The flower is already formed inside the bulb when you buy it.
Hyacinths, tulips and garden daffodils are different. They need several weeks of cold before they’ll flower indoors, or you get leaves and no blooms. Paperwhites are tender narcissi that simply start growing as soon as they get water and warmth.
That makes them the quickest win of the season. Pot them, water them, and they usually flower in four to six weeks.
Paperwhite bulbs are ready to go straight from the bag. Choose the biggest, firmest ones you can find.
Which paperwhite varieties to choose
Most bulbs sold as paperwhites are white and strongly scented. The scent divides people, so pick by how much perfume you want.
| Variety | Colour | Scent |
|---|---|---|
| ’Ziva’ | Pure white | Very strong, musky |
| ’Inbal’ | White | Milder, good for small rooms |
| ’Grand Soleil d’Or’ | Yellow with an orange cup | Sweet, less sharp |
‘Ziva’ is the classic and the one you’ll see most. Some people love its punchy scent, others find it too much in a small room. ‘Inbal’ is gentler. ‘Grand Soleil d’Or’ is a yellow tazetta narcissus that’s often sold alongside paperwhites and grown the same way. For other fragrant plants, see our list of the best scented plants for UK gardens.
How to plant paperwhites in a bowl of gravel
You don’t need compost or a pot with drainage holes. A shallow bowl of gravel works well, because the roots only need water and something to grip. Glass beads, washed grit or bulb fibre do the job too.
- Take a bowl about 20cm across and add about 5cm of gravel.
- Sit five or six bulbs on top, pointed end up, almost touching. They prop each other up as they grow.
- Trickle more gravel around them until only the top third of each bulb shows.
- Add water until it sits just below the bulb bases (see below).
- Stand the bowl somewhere cool and bright.
If you’d rather use compost, a gritty, free-draining mix works. Leave the noses showing, just as with gravel.
Pack the bulbs close together, noses up. The gravel holds them steady while the roots grow.
Warning: Paperwhite bulbs and plants are toxic to cats and dogs, and the sap can irritate skin. Keep bowls out of reach of pets, and store dry bulbs away from the kitchen so nobody mistakes them for onions.
Getting the water level right so bulbs don’t rot
Keep the water just below the base of the bulbs, never touching them. A bulb sitting in water rots from the bottom, and a whole bowl can turn to mush within days.
Pour water into the gravel until it just reaches the underside of the bulbs. The roots grow down into it while the bulbs stay dry. Check every few days and top up, as bowls dry out fast once the roots get going.
Roots usually appear within a week or two. A clear glass bowl lets you see the water level easily. If the water turns cloudy or smelly, tip it out and refill.
Timing paperwhites to flower for Christmas
For flowers on 25 December, pot your bulbs between late October and mid-November. Count back four to six weeks from the date you want.
Temperature fine-tunes the timing. A cool room at 10-15°C gives sturdy plants but takes a little longer. A warmer room speeds them up but makes the stems stretch. If a bowl is racing ahead, move it somewhere cooler. If it’s lagging, give it a bit more warmth.
| Pot the bulbs | Flowers open around |
|---|---|
| Mid-October | Late November |
| Late October | Early December |
| Early November | Mid-December |
| Mid-November | Christmas week |
| Late November | New Year |
| Early December | Early January |
These are rough guides. Varieties and rooms vary, so check your bowls and move them warmer or cooler as needed.
Staggering plantings for flowers all winter
One bowl flowers for two or three weeks. For scent all winter, pot a new bowl every two weeks from late October. Each batch opens as the last one fades.
Keep the spare bulbs dry, somewhere cool and dark like a shed or garage, until it’s their turn. Our guide to storing flower bulbs explains how to keep them firm. If you’re shopping for a keen indoor grower, a bag of bulbs and a pretty bowl make a lovely present, and our list of Christmas gardening gifts has more ideas.
Bowls potted a fortnight apart give a run of flowers from late November into January.
Why paperwhites flop and how to stop it
Flopping is caused by too much warmth and too little light. In a warm room away from the window, the stems race upwards, grow thin and soft, then keel over.
The fixes are simple:
- Keep the bowl at 10-15°C in the brightest spot you have.
- Turn the bowl every day so the stems grow straight.
- Loop raffia or push a few thin twigs around the clump for support.
Hyacinths grown indoors stretch in the same way. Our guide to growing hyacinths covers them.
Left, grown warm and dim: tall and flopping. Right, grown cool and bright: short and standing on its own.
The alcohol trick that keeps stems short
A weak alcohol solution makes paperwhites grow shorter and sturdier, without spoiling the flowers. It’s an old trick that really works.
Grow the bulbs in plain water until the shoots are 5-8cm tall. Then pour off the water and top up with one part gin or vodka to seven parts water. Use that mix for every top-up from then on. Don’t use beer or wine, as the sugar can cause rot. Stronger mixes harm the plant, so stick to the dilution.
Gardener’s tip: Start the alcohol only once the shoots are 5-8cm tall, never at potting. Starting too early slows the roots and weakens the bowl.
Plain water on the left, the weak gin mix on the right. The flowers are the same, the stems are shorter.
Paperwhites or other indoor bulbs?
Paperwhites are the fastest and simplest indoor bulb. The trade-off is that they’re a one-season treat.
Hyacinths and daffodils need weeks of cold first, but you can plant them in the garden afterwards. Amaryllis need no chilling either, give big single flowers with little scent, and can be kept for years.
Each stem carries a cluster of small, starry flowers. Bigger, firmer bulbs usually give more stems.
What to do after the flowers fade
Most people compost paperwhites after flowering. Forcing uses up the bulb’s reserves, and they rarely flower well indoors a second time.
They’re also tender, so they don’t usually survive outdoors in cold, wet UK winters. In a very mild, sheltered coastal garden you could try planting them in a sunny, gritty spot, but don’t count on it. For narcissi that come back every spring, our guide to growing daffodils covers the reliable garden kinds.
Once the flowers go brown, compost the old bulbs and start again with fresh ones next autumn.
Common mistakes with paperwhites
- Chilling them first. Paperwhites don’t need it. It just delays flowering.
- Letting water touch the bulbs. This rots them fast. Keep the level just below the bases.
- Growing them warm and dark. You get tall, floppy stems. Go cool and bright instead.
- Starting the alcohol too early. Wait until shoots are 5-8cm tall.
- Potting too late. Leave it past mid-November and they may not open until January.
Frequently asked questions
Do paperwhite narcissi need chilling before forcing?
No, paperwhites need no chilling at all. Hyacinths and garden daffodils need weeks of cold first, but paperwhites don’t. Pot the bulbs, add water and bring them into a cool, bright room.
How long do paperwhites take to flower indoors?
Usually four to six weeks after potting. In a cool room they may take a week or so longer. Warmth speeds them up but makes the stems tall and floppy.
When should I plant paperwhites for Christmas flowers?
Pot them from late October to mid-November. Count back four to six weeks from when you want flowers. Start another bowl a fortnight later to carry the display into New Year.
Why are my paperwhites so tall and floppy?
Too much warmth and too little light. Grow them at 10-15°C in your brightest spot and turn the bowl every day. Loop raffia or twigs around tall stems for support.
Does the alcohol trick really keep paperwhites short?
Yes, a weak alcohol solution keeps them noticeably shorter. Once shoots are 5-8cm tall, top up with one part gin or vodka to seven parts water. The flowers aren’t affected. Don’t use beer or wine.
Can you reuse paperwhite bulbs after flowering?
Not really, so most people compost them. Forcing uses up the bulb, and they rarely flower well again indoors. They’re also too tender for most UK gardens. Buy fresh bulbs each autumn.
What compost do paperwhites need?
They don’t need compost at all. A bowl of gravel, glass beads or bulb fibre is enough to hold the bulbs upright. Gritty, free-draining compost works too.
Are paperwhites poisonous to pets?
Yes, all parts are toxic to cats and dogs, especially the bulbs. Keep bowls where pets can’t chew them, and store dry bulbs away from food so nobody mistakes them for onions.
