Regarding nativism and flora, some years ago I organized a NARGS winter 
study weekend focusing on bulbs, and one of the speakers I invited was a 
woman from the Natural Resources Defense Council (NRDC) who had 
published on bulb importing from Turkey. I was aiming at information on 
the danger of depleting natural bulb populations for commercial sales, 
but what we got was a fiery talk on the danger of planting exotic 
species anywhere. First thing in the morning, too: it really woke up the 
audience. I have become cautious about anything put out by that 

It seems that invasive plant species are more likely to be spread via 
agriculture as weed seeds contaminating crop seed and animal fodder, 
than to emerge from ornamental gardens. However, it's interesting to 
visit other countries and observe my own "native" ornamental plants 
flourishing there as weeds: California poppy (Eschscholzia californica, 
and if you can spell that name better, go ahead) in Chile, where it's 
popularly believed to be a native wildflower (copas de oro); Russell 
lupines (Lupinus hybrids based on Pacific Northwest species) in New 
Zealand and southern Patagonia.

The Crocosmia mentioned here by Robin Hansen, popularly known as 
Montbretia, is common on the Oregon coast and many people think it's a 
native; it is a pest there, and a clump in my neighbor's yard has seeded 
through the fence. (The same neighbor planted a "wildflower mix" that 
caused me a lot more trouble, mostly with a Geum.) I always try to 
dissuade people from planting flower seed mixtures, which generally 
contain a few ferocious self-sowers.
