A Christmas pot doesn't have to be a December-only display. Plant it with genuinely hardy plants and it carries the front door from Advent through to the daffodils. Most of the best winter plants are at their peak after Christmas anyway.
The catch is that two of the season's best-sellers are not what they seem. One is a male skimmia that will never berry. The other is a cyclamen that can't take frost. Here is what to buy, what to skip, and how to plant a pot that lasts.
01At a glance
- Backbone: a skimmia, or a small box or holly.
- Colour: winter heath (Erica carnea), hardy cyclamen, winter pansies and violas, Christmas rose.
- Berries: a female or self-fertile skimmia, or Gaultheria procumbens.
- Trails: small-leaved ivy over the rim.
- Scent: sweet box (Sarcococca), for a pot right by the door.
- Skip outdoors: the florist's cyclamen, if you want it to last past New Year.
- Pot: frost-proof, on feet, filled with peat-free compost and planted close.
02The plants, honestly
- Skimmia. The RHS says female skimmias only set berries with a male nearby, and one male can pollinate several females. The famous red-budded 'Rubella' is a male. Its buds are showy all winter and open into scented white flowers in early spring, but it will never berry. For berries, buy a female and a male together, or Skimmia japonica subsp. reevesiana, which the RHS lists as self-fertile. The label should say which you're getting. Skimmias are happy in partial or deeper shade, which makes them good for a north-facing door.
- Hardy cyclamen, not florist's cyclamen. The RHS says Cyclamen coum flowers "from January to March" and survives "the severest weather". C. hederifolium flowers in early autumn, and its marbled, ivy-like leaves then give ground cover from winter to spring. The florist's cyclamen, C. persicum, is the one on every supermarket shelf. It's the plant in our cyclamen profile, and the RHS rates it H1c, a summer-only outdoor plant. The RHS winter container guide says it "is not hardy but will usually last until the new year in a sheltered location."
- *Christmas rose (Helleborus niger).* Very hardy: the RHS rates it H7. The name oversells the date, though. The RHS gives its flowering as "from midwinter to early spring", so don't count on flowers for Christmas Day. It likes neutral to alkaline compost and partial shade. Our hellebore profile has the details.
- *Winter heath (Erica carnea). The RHS calls it "a lime-tolerant heather", with flowers from winter into early spring. That makes it the heather for an ordinary pot. Don't confuse it with ling (Calluna*), which our heather profile notes must have acid soil. See our winter heath profile.
- *Checkerberry (Gaultheria procumbens).* A creeping evergreen about 15cm tall with scarlet berries roughly 10mm across. The RHS rates it H5 and lists it for acid or neutral soil. In a mixed pot, give it a few handfuls of ericaceous compost round its roots. See our wintergreen profile.
- Ivy. Small-leaved ivy trailing over the rim softens the whole pot, and our profile rates it fully hardy.
- *Sweet box (Sarcococca confusa).* The RHS describes "very sweetly scented, creamy-white flowers" in winter, followed by black berries. It's rated H5 and likes shade. It eventually makes a 2m shrub, so plan to move it into the ground in spring.
- Winter pansies and violas. The RHS says they "flower intermittently during mild spells in winter", then properly in spring. They're cheap gap-fillers.
- A small evergreen centre. The RHS suggests box, bay, skimmia or euonymus as the focal point of a larger winter pot. A small box or a young holly both work.
03Planting it
- Choose the pot. The RHS says "frost-proof terracotta or containers made of plastic, fibreglass or wood". Ordinary terracotta can crack in a freeze. It needs drainage holes, and the bigger the pot, the slower it dries out.
- Raise it. Stand it on pot feet or bricks. The RHS says this helps drainage and prevents the freezing conditions that crack pots. See protecting plants from frost.
- Fill it. The RHS suggests peat-free multipurpose compost with added John Innes for skimmias. For hardy cyclamen it suggests peat-free John Innes No 2 with extra grit and leafmould or fine bark. A mix of the two suits the whole pot. Skimmia doesn't need ericaceous compost: the RHS says so plainly.
- Plant it full. Plants hardly grow in winter, so the RHS says to start with good-sized plants, and enough of them to make an impact straight away. Put the tallest in the centre or at the back, the heathers and cyclamen in front, and the ivy at the rim.
- Tuck in bulbs. Dwarf daffodils, crocus or tulips between the plants turn it into a spring pot as the winter plants fade. Daffodils should be in by mid-November and tulips go in October to November. All three are toxic to pets, so skip them if your dog digs (see below). See planting spring bulbs.
- Water it in well, then let it drain.
04Through the winter
- Water carefully. The RHS warns that pot compost "can soon dry out in mild spells". A pot sheltered by a porch gets almost no rain. Check it weekly, and water only when the top feels dry.
- Don't feed. The RHS says it isn't necessary in winter.
- Wrap the pot in a hard freeze. The RHS suggests bubble wrap round the container in severe weather, to protect the roots.
- Deadhead the pansies to keep them flowering.
- In spring, move the skimmia, sweet box and hellebore into the ground or into bigger pots. Let the bulbs take over.
05Pets and children
Several of these plants carry flags. A pot by the door is within reach of every passing dog.
- Skimmia. The RHS says the fruit "may cause a mild stomach upset if ingested". Our skimmia profile flags the berries and leaves.
- Cyclamen. The ASPCA lists all cyclamen as toxic to dogs, cats and horses. After large ingestions of the tuber, the signs include heart-rhythm problems, seizures and death. A dog that digs in pots is the real risk.
- Christmas rose. The RHS says it is "harmful if eaten" and the sap irritates skin. Wear gloves when you plant it.
- Ivy and holly are both toxic to cats and dogs if eaten, per our ivy and holly profiles.
- Box. Our box profile flags it as toxic to pets if eaten, causing vomiting and diarrhoea.
- Spring bulbs. Daffodil bulbs are the most poisonous part of the plant, and dogs that dig them up are the usual casualties. Tulip and crocus bulbs are toxic too. If your dog digs in pots, leave the bulbs out of this one.
- Checkerberry and sweet box. The RHS marks the berries of both as not to be eaten. Our wintergreen profile also notes that the leaves contain methyl salicylate.
- Winter heath, pansies and violas. Our winter heath profile has no toxicity listing for it, and we don't yet have a profile for pansies or violas. We make no claim either way. Don't treat them as safe.
We make no safety claim about any plant we don't have a profile for. If a plant isn't covered here, that doesn't mean it is safe.
If a pet has eaten any of these, take the plant away, don't try to make them sick, and ring your vet or the Animal PoisonLine on 01202 509000. It is a paid 24-hour service (£35–£45 a call). If you think a child may have swallowed something harmful, call 999 or go to A&E. Call NHS 111 if you're not sure.
Save your money
Glitter-sprayed or painted plants. The colour is on the plant, not in it, and new growth comes through in its own colour. A plain winter heath or a budded skimmia looks just as festive and keeps going.
A florist's cyclamen for an outdoor pot. It's fine for Christmas in a sheltered porch, but expect to replace it in January. Hardy C. coum survives the frost and comes back every year.
A 'Rubella' bought for berries. It's a male. Its buds are the show.
Ericaceous compost for skimmia. The RHS says it isn't needed. It also says yellowing skimmia leaves usually mean dryness or too much sun, and that iron tonics are unlikely to help.
Pot feet. Bricks do the same job.
A new pot every winter. Plant the shrubs out in spring and you have next year's border, or next year's pot.
