If "over here" = east of the Cascades check soil and water suitablility, if no montbretias (Crocosmia crocosmiiflora) being seen over there that could be a red flag--they tend to be common where adapted*, as they are prolific and easily grown for the most part (rather heavy damage from mites is often seen on them during our dry midsummer conditions in Seattle area). And the hybrid 'Lucifer' is also prevalent, it may be significant that you saw it all over on your trip but not where you live. Sunset WESTERN GARDEN BOOK gives west-side only Zones for Crocosmia (in PNW), says "Where lows range from 10 to -5F/12 to -21C, provide winter mulch. In colder areas, dig and store over winter." *Actually a pest in Hawaii
