Last year I posted a pic of this shrublet flowers.
Acantholimon is a huge Asian, mountainous genus. A. libanoticum is one of the westermonst species, growing in the Lebanon Mts and Mt Hermon, where this pic was taken. It blooms in July after most other plants are drying. It is a cushion-like spiny plant, typical for the sub-alpine (Tragacanth) belt. Here you can see it after blooming when the corollas are gone and the papery calyses are still visible.
