Just bought this tiny little guy.
var. tuerckheimii is a paler form than the standard. I was slightly confused when checking the name online as I found pictures of tuerckheimii which seemed darker pink than the standard, but then SBOE sells one under this name and their picture shows it the same colour as mine.
Anyway the flowers are tiny. About 6mm in the main body of the flower, with a spur at the top arround 10mm and the lower curved backwards spurs are about 5mm each.
It has two open flowers and a further five buds waiting to open.
Really difficult to take pictures of, and in the first picture it's focused so close that the dust on the camera lense showed up. It still shows the flower well though.
