yes I have a red and white dahlia and red and white dianthus too. in the spring red and white tulips too. A neighbour had roses like in Alice in wonderland.
why do you ask?

I can only think because red and white together is bad luck - ie blood and bandages from the first world war. I am probably completely on the wrong track!! Anyway have you seen penstemon hot lips? They are a beautiful red and white flower.

Cammomile I have heard same thing too so I won't put those colours together in any way

Hi thankyou to you all for your comments.:)

Hi Mark you already asked this question in a different form and were answered. You only need to look at municipal bedding areas to see red and white flowers together.

Well if it only came about from the first world war, I can't see the harm in it. Sorry I didn't see the previous answers - I was working backwards looking at the questions.

Hi moon grower ,I know i already asked the question earlier in a different format.I just wanted to know if other gardeners had mixed the two colours in there gardens.I will be parting them as i have had mixed responces.Lol im happy they are in pots so they can be easily moved.Thanks mark

Just thought of something else as not to have them together the war of the roses ( red and white) Lol.Sorry i started this debate.:)

It is a load of rubbish about bad luck.

I am sceptical on that point.

My local park has red and whites together next to the cenotaph. PATRIOTIC! If you are English.

How would they create the St George's Cross in flowers without putting red and white blooms together.

Mark putting two colours of flowers together is not going to cause death. Neither does in symbolise death. I don't think we have any red flowers in our garden (at least I can't 'think' of any red alpines) but it would not bother me if we did.

Hi Alextb.Yes i am english i was just asking a general question which many people do ponder.I didnt mean to offend anyone.I only asked about mixing red and white flowers due to a old saying that they shouldnt be mixed in which i have found out this was the case only in hospitals and the war.Please read from the start of the question.Regards mark

Sorry for upsetting anyone i didnt mean to i was just asking a age old question but now it seems to have turned to quite a sour debate.I thought this was a gardening site where we could ask questions.Sorry again mark

No problem Mark as always it's a matter of preference.It's your garden and personally I think it brightens up an area.Your red and white cyclamen look spectacular together :)

Hi Aster thankyou for your lovely responce in which the question was intended.Also thankyou as i now know what they are called as i didnt know before.:)

They are lovely little plants and will self seed.When the flowers finish you will notice the stems twisting and lowering the seed head to the ground to deposit seeds.You can gather them to plant elsewhere or leave them to fill your pots.

Wow i didnt realised they do that as im a newish gardener.My last garden was only 10ft by 20ft and now i have got a very big garden to my old one.Will certainately be looking for the seeds.Thankyou for the info.I tend to buy plants with no labels hence the reason why i didnt know there name.

You can always ask on here someone will know :)

The resorts around here often combine red and white Madagascar Periwinkle (Catharanthus roseus) in their summer flower beds.

I don't have red and white together as I am a Newcastle United fan........actually that doesn't come into it. Yes, I have a red Persicaria amplexicaule 'Firetails' with a white Anemone 'Honerine Jobert'.

Mark dont worry so much!, red and white flowers are truly beautiful and if you think about it all flowers have leaves which are green so no flower is just 'red & white' anyway, and you ask as many questions as you please on here. They will always be answered. Take a look at Camillia's photos she lives in Chitwan and grows the most amazing 'Clerodendrum thomsoniae, bleeding heart vine',lts red and white flowers are glorious, now you cant argue with nature can you !

I have a white Clematis with red Tropaeolum Spec. climbing up through it...Beautiful....

In the dim and distant past I was a nurse and my first ward sister went mad at me for putting red and white flowers in the same vase. A patients relative obviously knew as little as me about the significance of this particular flower colour combination. Sister would have been old enough to have worked in hospitals in WW1 and I think a lot of their notions have gone for good. Eg .did you know they used to incarcerate unmarried mothers in mental institutions. Some of them were only released in the 1960's when doctors realised why they were there. Nowadays you are not allowed to take flowers in to hospital at all as it is supposed it may do some harm. I suspect it is more to do with the fact that some wards looked more like flower shops than wards. It is time consuming to look after flowers in the heat of a hospital ward. We used to put the vases in the sluice room overnight to save the patients from losing oxygen to the flowers when in actual fact flowers give off oxygen in the night. I grow all sorts of combinations in the garden but I prefer colours which do not clash.

I'd never heard of these myths regarding red and white flowers, so for sheer contrast I've got two window troughs containing red and white Busy Lizzies, a trough containing a lovely red pelargonium flanked by two white petunia plants and a small part of the low border in the garden contains red and white dianthus. To my knowledge nobody in the region has died lately and I'm the luckiest person alive anyway!

When I was nursing, in the days of flowers on wards, the nurses were expected to sort them out everyday. It was a terrible thing to put red and white flowers together in the same vase. I never connected that superstition onto gardens,as there is always some other colour nearbye. Where does an arrangement begin and end. Even a patriotic red and white cross might have blue borders of Lobelia near too it!

Our hospital gardens were always full of flowers of all colours. We had some long stay wards and the gardeners provided flowers to cheer the patients up. I think in the three years I was there only one person died so it did not affect the many and has passed in to hospital folk lore along with nurses having to be indoors and lights out at 10pm. LOL I think we need to turn the clock back or we will have a worn out before their time next generation of OAPs.

Yes Mark, please don't worry at all. :-)

Enjoy the site!

plants were taken out at night as they compete with the patients for oxygen in the dark. they produce oxygen during the day when they photosynthesise in the light. They dont like plants in wards now incase of hayfever/reactions apparently. shame it is lovely to have flowers cheering up the dull wards. But looking after flowers detracts from the patient's care.

Sorry Mark we seem to be taking this conversation on to a different plane here. Seaburngirl I think the following copied from the site below sums up why we need not worry about plants in bedroms. I had not heard of the hay fever connection but people do seem to suffer more from allegies nowadays. I agree the wards were brightened considerably from having vases of flowers. .
Nighttime Battle?
At night, when photosynthesis can’t take place, plants continue to consume oxygen but they don’t release any back into the room. Would that mean that plants really do compete with humans for oxygen?

Well, not really. The amount of oxygen the plants in your bedroom use at night is trivial. Think about the earth as a giant bedroom and you’ll see that animals would be in pretty big trouble if plants used up a significant amount of oxygen every night.

I hope we have put your mind at rest about the mixing of colours, the consensus seems to be it is all about personal choice.
