Crocus rujanensis in outer appearance looks something similar to C. dalmaticus and C. sublimis and differs from the two in a combination of characters rather than in one distinct feature. All my samples of it were collected at locus classicus on Rujan Planina, so they undoubtedly are correctly named. In my garden Crocus rujanensis is less vigorous than its closest relatives, most likely due to the lower altitudes where it occurs in wild; it seems that our winters are somewhat too harsh for it, but in a milder climate it is an excellent garden plant – well sets seed and is a good increaser by corm splitting.
