I have been photographing Dianthus armeria for a couple of weeks--a challenge not only to identify but also to pull off a detailed shot. The bright pink oversaturates with ease, blotting out detail. Deptford Pink is found all around the lake and always in small patches. Below is about as extensively grouped as it gets.
From "an historical account of the towns, villages, and hamlets...":
"The Dianthus Armeria, which abounds in this part of Kent, was called by the old botanifts, who found it in this parifh, the Deptford pink."
