As a full sun to light shade plant I would not expect much in full shade. Do you keep the pot in full shade? If not I would put it there and see how it does before planting in the ground. As a member of the Arum family I would suspect it may go for several years without blooming. Al

Mine have been in the ground for at least ten years and have only started blooming the last four. I made the mistake of planting one too close to a tree but when I decided to dig it up, a huge broken up bulb came up. The next year, it came up right next to the tree again! They do the best under the Palm trees where there is filtered sun. The ones in a more shaded location are leaning toward the light. Mine go completely dormant in October and don't pop up again until May, so the occasional freeze doesn't affect them.

Here is a picture of my flower, the flies were pretty thick around it for about a day:

Honestly, I'm not sure how you can get advice if you do not provide a species or even a genus for that matter. The last picture is of Amorphophallus paeoniifolius, but other Amorphs are called "Voodo Lily" as are the larger Typhonium. Surely, you can bloom Am. konjac or T. venosum in shade (I have for many, many years in zone 6). Needless to say, these can also be grown in full sun in my climate, but it is not a necessity by any means. Either of the 2 Amorphs mentioned above can reach several pounds before flowering and are typically 4-5 years old by then :o) Dan

If your Brugs grow well there and flower, Amorphophallus or Typhonium (Voodoo Lilies) should be fine as well.
