Those from the lower valleys may be rather tender, and those from higher elevations may require a strict, rather dry winter dormancy, just as plants from, say, the Rocky Mountains do. Do we know the elevational range of Ixiolirion?" For Ixiolirion tataricum, the elevational range is not noted, but for another species, I. songaricum, it's listed as 400 m - 1600 m. The geographical range of I. tataricum suggests hardiness in spite of elevational range, depending on the source of the plant. From the eFlora of China: ================== 1a. Ixiolirion tataricum var. tataricum Perianth azure to dark violet, segments 1--7 mm wide, not connivent proximally into a pseudotube. Fl. Apr--Jun. Valleys, sandy places, waste grasslands. N Xinjiang [Afghanistan, Kazakhstan, Pakistan, Russia, Turkmenistan]. 1b. Ixiolirion tataricum var. ixiolirioides (Regel) X. H. Qian, Bull. Bot. Res., Harbin. 4(2): 158. 1984. Kolpakowskia ixiolirioides Regel, Trudy Imp. S.-Peterburgsk. Bot. Sada 5: 635. 1878; Ixiolirion ixiolirioides (Regel) Dandy; I. kolpakowskianum Regel. Perianth light blue, segments 1--3 mm wide, laxly connivent proximally into a ca. 1 cm long pseudotube. Fl. Apr--May. Stony slopes. N Xinjiang [Kazakhstan, Kyrgyzstan]. Rudolf Kamelin (pers. comm.) notes that this taxon differs from var. tataricum in other characters and would be better recognized at the rank of species. =================== Mark McDonough Pepperell, Massachusetts, United States email@example.com "New England" USDA Zone 5 ============================================== >> web site under construction - http://www.plantbuzz.com/ << alliums, bulbs, penstemons, hardy hibiscus, western american alpines, iris, plants of all types!
