What is this flower called

Can some kind soul tell me what flower this is and best way to propagate it.
Thank you

 

Looks like rose campion - lychnis coronaria. A short-lived perennial - it will seed itself or you can divide it in spring (probably too late this year). BBC - Gardening: Plant Finder - Rose campion

(The Royal Horticultural Society website would give more information but is playing up at the moment!)

 

Hi Mint.

Your plant is Silene/Lychnis Coronaria and the best way to propagate it is to wait until the flowers have been pollinated by the bees.Leave the flowers to gradually die off and you should then be left with a seed pod which should go from green to brown over the coming weeks.Keep and eye on them and just as the seed pod is starting to open at the top,you can then pick the pods and either shake them over your borders where they will germinate or else you can pick them off and put them into a paper (not plastic) bag where the seeds will fall out as the seed pods dry even more.You will probably have to pick out the dried out seed pods after the seeds have all ended up in the bag and you can store them for sowing in the Autumn or can sow them as you wish.

I have never tried to propagate them from cuttings as they grow very well from seed.There is also an Alba(white) version that you can buy

 

Thank you for your replies, I will collect the seeds and try to grow it from seeds next year.

 

If you sprinkle some of the dried seeds round your garden in the warm weather then they should germinate and will make small plants that will overwinter and will flower now like the ones in your photo have.

 

Hello mint, the best way to do them is to sow them as soon as they're ready,

Remember that if Mother Nature produces seed now then she's telling us that now is the right time and the conditions are right to sow.

They'll germinate quite quickly and provide you with young plants that can stay out all Winter and grow steadily away to flower next year.

PS.... You don't need many, there are hundreds of seeds in each seed pod.
