Deptford Pink

Deptford Pink (Dianthus armeria) is, I believe, rarely found growing in  the wild in Britain. Sometime ago  I bought a packet of seeds, and now the Deptford Pink self- seeds around my garden. The plants are wiry  and insignificant, easily mistaken for weeds. The  flowers are very small (only about10 mm in diameter),  but I am always  surprised and pleased to find them as they are such a bright, deep, pink, and I admire the  tenacity  of the plants. 
Apparently, it was named  after Deptford in SE London by a 17th century  naturalist called Thomas Johnson who found a pink flower growing there. However, that is now thought to have  been the Maiden Pink. (Dianthus deltoides).
