I enjoy reading speculative fiction a lot, but I probably enjoy speculative poetry even more. It is a narrower field, in terms of readership, but there is a surprising large amount of very good speculative poetry available through various magazines and chapbooks.
I especially enjoy coming across speculative poetry that is written by poets who are otherwise considered "mainstream" writers. Al Purdy has written a fair bit of speculative poetry, as has Edwin Morgan. In Charles Albano's haiku collection One Summer, a Thousand Days (reviewed here), there is a whole section dedicated to scifaiku. The list could go on and on, because there are plenty of good poets who write poetry that some might consider "just" genre poetry.
If you'd like to have a look at more speculative poetry, or if are perhaps looking for market to publish your own work, you can visit the Science Fiction Poetry Association. And one of my favorite publishing house that is dedicated to speculative fiction is Sam's Dot Publishing. There are lots of magazines and chapbooks there.
