Paul, You may have already discovered this in your Google searching, but if you want to compare the two directly yourself by growing them both, you can of course get Aristea eklonii from several sources including the Saunders's Silverhill Seeds. Plant World Seeds in England sells seeds of Libertia caerulescens <http://plantworld-devon.co.uk/test.asp/…>. They describe it as "A most unusual coloured dwarf Chilean libertia. Compact basal iris-like leaves, the intriguing flower heads being that rare shade of palest china blue." They have a tiny picture of the flowers that does look a lot like A. ecklonii. -- --Lee Poulsen Pasadena area, California, USDA Zone 9-10
