There are a number of other species related to C. choziatowskyi that occur in the Caucasus, barely known in cultivation. Of most interest are C. elegantissima Grossh. (stems procumbent, 10-15 cm, flowers numerous, 2-3 cm long, new to cultivation); C. kemulariae Fomin (stems procumbent, 15-25 cm, flowers 2-3 cm long); and C. ossetica Bieb. (stems arching, 20-40 cm long, flowers numerous, 2-3 cm long, new to cultivation). All plants suitable for the rock garden and dry walls. All do well in Z 5; C. kemulariae can grow in zone 4. Both C. elegantissima and C ossetica are new reports for gardening.
