hist-brewing: hard to find spices

[Chuck Mongiovi]

Hi all,
I'm in search of a specific herb to do a Digby mead recipie and all of my
herb / spice sources are striking out .. Does anyone have any good spice
sources they'd be willing to share .. Specifically, I'm looking for
something called Sea Wormwood (Artemesia Maritima, not Artemesia Absinthium)
.. http://www.botanical.com/botanical/mgmh/w/wormwo37.html#worsea ..

Any ideas?
