Buy Romneya coulteri tree poppy: Spectacular poppy-like flowers with golden-yellow centres

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun
  • Soil: fertile, well-drained soil
  • Rate of growth: average
  • Flowering period: July to October
  • Hardiness: frost hardy (needs winter protection)

    Papery, pure-white, poppy-like flowers with golden-yellow centres from July to October and handsome, deeply lobed, grey-green leaves. This wonderful, white tree poppy makes an excellent specimen plant for a sunny mixed border. Often slow to establish and resentful of disturbance, it requires fertile, well-drained soil, and shelter from strong winds. Can be propagated from root cuttings taken in the winter-early spring months.

  • Garden care: Cut back flower stems close to the base in March. Provide a deep dry mulch in the winter months for protection.

Unfortunate experience


I have been buying from you for a long time. The last two plants I bought were alas a failure




Show stopper


The Crocus plant replaced one from another source which didn't survive the winter. This one has flourished and looks amazing when all it's large white flowers are fully open.

Why won't my Romney flower? It's in its second year in a reasonable sunny mixed boarder with fertile soil.


Hello there These lovely plants can take time to get established, but as long as you make sure it has the right conditions, like a sunny sheltered spot with a fertile well drained soil, then in time it should flower. You could also apply a good layer of mulch in the spring.

I have a plant in my garden, planted this last year, it produced one beautiful flower this year . I'm on chalk and thus free draining soil. None of the previous questions or information on website say about feeding the plant. I'm very keen for this to get established and flourish what would you advise ? Also I'm still not clear about the cutting back you mean cut back stems that have flowered and leave others ?


Hello, These are often very slow to settle in as they resent dispturbance, however once they do they tend to spread quite quickly by suckers. Therefore I think you simply ned to give it time, however they do like a ferile soil, so do apply a generous layer of mulch in spring, as well as a dry mulch in autumn to help keep the roots insulated. during the winter. As for pruning, we refer to cutting back the flower stem (ie stalk) nt the whole stem, although once the plant gets better established, you can cut back any damaged stems to healthy growth in spring.


Hello.... I am a gardener for a nine acre garden in Sussex, and the lady originally started out with 5 of these plants before I arrived. She now has one left and last year I tried to take a runner with some shoots coming from it and planted it in some gritty compost. After a while those shoots started to come through as little babies and I tried to move the peice of bark it was on to separate pots. They didn't mind that. they got to about 4cm high, went yellowish and croked it!!! they didn't get over watered and I tried to keep them damp. what should I do differently if I want to try this again??? I know they are notoriously difficult to grow on!

Hello, You are right in thinking that these are difficult to propagate, and that is why they are so expensive to buy. I am not sure why your last batch died, but the best way to propagate them is by root cuttings in winter. Carefully expose some of the rootball by digginhg a hole about 45 - 60cm feet away from the base of the parent plant. Using a sharp knife of pair of secateurs, make a straight cut and sever sections of healthy root (at least 10cm long) that are roughly 1 - 2cm in diameter. Cut these into 5cm long sections, making a sloping cut at the base of the cutting and dust with a fungicide. Using one pot per cutting (filled with soil-less, freely draining compost) gently press the cuttings horizontally into the top of the compost and then cover with a 1cm deep layer of sharp sand. They should then be kept in a coldframe and watered sparingly. They tend to resent transplanting, so when they are large enough to plant out or pot on, try to avoid too much root disturbance. I hope this helps and good luck


Romneya for planting in a pot? and will rabbits eat it? Hello I would like to buy a Romneya plant for my mother but it would have to live in a pot, do you think it would be ok? She lives on the Wirral just back a few streets from the sea, but her garden is a courtyard, and very well sheltered and protected by some woods and other houses. It does get the sun, and I doubt it would get much salty air. They usually don't get much frost their either. Can you advise me please? Thank you Philippa

Hello again Philippa, The smaller cultivar would definitely be a better option for a pot. As for their stems, they are really sub-shrubs so do develop some woody stems, but they don't get really tough, and therefore I suspect the rabbits would eat them if they take a liking to them. I hope this helps. Helen Plant Doctor

Hello Philippa, It is always really difficult to give a definitive answer, but ideally these plants should be planted in the ground. I suspect though it will be fine if it goes into a large pot filled with John Innes No 2 compost and kept well fed and watered. I hope this helps. Helen Plant Doctor

Philippa Biddle

Hi thanks for that. I am all for giving things a try, so I will go for it, or it's friend. After I sent my email I noticed you had a smaller variety. Would that be a better bet perhaps? Also another question re same plant....... My mum asked for this Romneya, but apart from pictures I have never seen one. I work as a gardener in Norfolk and I quite fancy one for a new garden I am developing there, but we do have a rabbit problem. Does this plant have a woody stems? or would it be soft and tasty for some very naughty, hungry wild rabbits who have managed to eat a whole Senecio hedge this winter!!!!! Many thanks for your help. You website is fabulous by the way. Philippa

Romneya coulteri Hi, Last year I purchased a Romneya coulteri from you. This year the 2 stalks the plant already had when purchased flowered with 3 flowers on each stalk. The plant has now gone beserk with stalks everywhere. These are all quite tatty as something laid it's eggs on the plant and proceeded to eat lots of it. My question is on your web site it states "Garden care: Cut back flower stems close to the base in March. Provide a deep dry mulch in the winter months for protection." Sorry for my ignorance but where it states flower stems does that refer to the stems on the two which flowered? I don't know whether to cut back all the stalks in March or just the original 2 that flowered. I don't want to cut everything down and miss out on those flowers next year, if I cut back everything will I still get flowers next year? I suspect the answer is yes but I want to make sure. I hope this makes sense and thank you for your time. Georgina

Hello Georgina, As these plants are not fully hardy, they are usually cut back to the ground by hard frosts each year. In milder areas where the frosts are not as severe, you should cut them back to a low, permanent framework in early spring as the buds begin to swell. As they produce their flower on stems that have grown in the current year, this will not affect their flowering. I hope this helps. Helen Plant Doctor

How to control diseases

Prevention is better than cure with diseases in the garden so keep your plants growing as strongly as possible – allowing them to fight off infections naturally. A weak plant is much more likely to fall prey than a good, sturdy one. Also be vigilant! Try
