Ask Mr. Smarty Plants

Thank you for alerting us to the misleading wording of our NPIN entry for Allium canadense (meadow garlic).  The sentence you referenced was discussing the closely related European species, Allium vineale.  The entry also discussed another non-native species, Allium ampeloprasum.  To avoid further confusion, we have stricken our discussion of the non-natives from the web page for Allium canadense.

There should be no non-native (outside North America) plant species included in the NPIN database.  Some entries, like the one you read, may include some discussion of non-naitve species, but that would be very unusual.  The native origins of a few species are in dispute among botanists.  We make decisions on a case by case basis for those exceptions based on the best evidence available.

We do not have a definitive answer for your final question.  Most questions of nativity date to the time of arrival of Europeans to North America some 300 to 400 years after the period of time you're researching.  We know that Native Americans traded and spread edible plants among tribes and over large areas, but our information is not nearly so exact to say whether or not certain species occurred in Florida in the 12th century.  Unfortunately, none of the North American indiginous peoples kept written records.
