tansy

I saw them as recently as 5 years ago, and you're right, the tansy seems to have spread since then. Now all I see are the similar centocha moth

A few years ago, they were hot on using cinnabar moths to control tansy ragwort (see http://en.wikipedia.org/wiki/Cinnabar_mo...), and it seemed like I saw less tansy then. Haven't seen any of the caterpillars lately, though. Guess they died out, as they were supposed to.

heh, except silver leaves look even more silver. I have two cameras made by Olympus. One I use in my workplace because it is far superb for low light photograpy. The other I use for it's generous zoom capability. Both also do great macros

Bah! Low light photography ruining my identification skills!

Check the link I posted, and the one posted by shebebusynow. Senecio vulgaris is another common invasive here, and it's kind of nice to know it's name. Really enjoying project noah... the silvery leaves are from the low light photography and the bit of reflected dappled sunlight

hmm, the leaves in the last pic look real silvery. what is commonly called Tansy Ragwort is Jacobaea vulgaris, the cousin of Dusty Miller.

It doesn't have silvery leaves at all. I've trying to look it up, but this computer doesn't have a pdf on it(and not enough resources to deal with one - adobe was messing with something). All the noxious weed resources call it tansy ragwort, but no latin name

Actually, the silvery leaves lead me to believe that it isn't tansy ragwort or tansy, but dusty miller.

I know some people call this "tansy", I try to make sure to differentiate it from Tanacetum vulgare, more commonly called "tansy".
