Some Neophytes in North Rhine-Westphalia
'Neophytic' and 'adventive plants' are wild plants, which were not originally growing there, but immigrated or were introduced since 1492 when Columbus reached America. 'Neophytic' means those of the immigrated or introduced plants, which are able to adapt to the climatic and other conditions, and last permanently. The more general term 'adventive plant' is used for any plant which arrives newly, even if it isn't able to last. Plants which immigrated or have been introduced earlier than 1492 are called 'archaeophytes', but these are not the theme of this page.
 
Some findings of outstanding neophytes from North Rhine-Westphalia are presented here. Frequent neophytes as Solidago, Amaranthus etc. aren't mentioned here, these are e.g. shown in Neophytes in the 'Kurpfalz', the presentation on the neophytes of the region around Mannheim and Heidelberg in Baden-Württemberg.
