What is the pink plant?

Any idea what the pink ones are?
Believe they are perennial - they flowered about a month ago and still thriving. 30cm height more or less.
I want to buy some more - can I buy the small plants as I don’t think I can grow from seed as do not have much space in house or have a greenhouse.

Dianthus/Pinks. I assume they smell nice and spicy. Yes, you can buy them as plants but are easy peasy as seeds.

 

Thanks - I can’t smell much as I get hay fever

can I just seed outside? When would I do that?

Thanks

 

I have, but I am not in the UK so best someone from there come along to answer that. What part of the UK are you?

 

I am in north London

 

Thank you. It helps people to advise if your location is known,

 

They self seed in this garden, so I assume you could just collect and scatter the seed. As to when, once the seed is ripe. Seed head just pop open with tiny black, flat seeds.
They are actually one of the fastest germinating seeds going. I have had them germinate overnight from sowing in the morning.
