It also appears the the Hemlock is on a timer and appears at 11:00am central time in all regions. Not sure at what time it poofs, but by late evening it can no long be found.
I have found a way to get hemlock to appear at 12pm Noon ET - the old trick of changing the Time Zone on your XMB. Set the Time Zone on your XMB to after 12 pm Noon, but before 1pm whatever it is on the world (NOTE: use the clock in the upper right as a gauge to when the TZ is set correctly). DO NOT change the actual time on your clock.
I tested this theory yesterday when it was really 7:35am ET. I changed it to Brussels time (I think) - it was definitely after 12pm Noon. I logged back into Home and rezoned to the Adventure District - lo, and behold, hemlock a plenty. Was able to finish getting the current wave of Halloween curses and rewards until the next release.
Hope this helps!
