Wild sweet peas

Had lunch in Primark today. Now there's a phrase you don't hear too often! For those of you who don't live in the UK Primark is a cheap (and sometimes nasty) shop aimed at the young.
We had  our camera club meeting and usually go for a coffee afterwards in the museum but decided to go to Primark as their coffee shop has a high vantage point looking out over the High Street. It was quite nice as an alternative but the noticeable thing was that all the customers were of the older generation and most probably not customers of the shop.
On the walk home I noticed these flowers growing on the edge of a building site. They were slightly smaller than the ones I grow in the garden but their colour was quite exquisite.
