Harold Koopowitz once told me very nearly this same thing about some of 
the bulb types that have gone through centuries, even, of Dutch 
treatment and selection to what they are today. I dimly recall that he 
was referring to tulips and hyacinths especially, since hyacinths 
originally were mediterranean climate plants, but most of the Dutch 
cultivars don't do well at all in our area (Southern California). And 
that had the Dutch not chosen results of all their tulip breeding that 
only did well in their climate over the centuries, but instead tried 
crossing and growing out all sorts of hybrids regardless of their 
adaptability to the Dutch climate, we might today have some spectacular 
tulip cultivars that would grow well and naturalize here in California 
rather than needing to be grown like annuals and be pre-chilled in the 
refrigerator, etc.
