Underground trees spawn in newly created suitable locations once their biome is uncovered. So far, this requires a Subterranean tile of soil, with a full soil wall underneath it. They do not spawn on subterranean soil tiles located above rock walls. From Toady's comments, I speculate that they will spawn on subterranean muddied tiles without a full soil wall beneath them. I have not tested this second hypothesis.The Architect 05:53, 26 April 2010 (UTC)

That would be entirely consistent with behavior from 0.28.181.40d. --Quietust 12:52, 26 April 2010 (UTC)

I have the surface level (z 0), then below that I have a whole z level of soil mined out (z -1). Below that I have a whole z level of soil mined out (z -2). Below that I have rock all mined out (z -3). Plants grow on z -1, but not on z -2. I think that confirms what you were saying. Mason ^(T-C) 16:38, 26 April 2010 (UTC)

They will spwan quite happily on muddied areas of soil. This has happened on several maps I've played where I've flooded some farmland and access corridors, then found underground trees. They then grow on the muddied areas not covered by farm plots.--Nimblewright 16:59, 1 May 2010 (UTC)

Any list yet of the colours of the wood, and the products thereof? I know that at the very least, feather wood and the underground wood have different colours. --AndrDrew 00:13, 6 May 2010
