Summary0010281: underground soil/mud in an ocean biome will never spontaneously grow underground plants after breaching the caverns
Descriptionany tile in an "ocean" biome that would otherwise spontaneously grow underground plants/moss/trees does not do so. These tiles remain valid for farm plots (and all 6 normal plants will grow there), and the cavern under the ocean starts with the normal array of plants for its depth. I have not yet managed to test if the original cavern vegetation will regrow or not.
Steps To Reproducedig out an area underground in an "ocean" biome that is either soil or rough stone muddied with clean water. breach the caverns. wait a year, and note the complete absence of cave moss & the other plants that have grown in similar areas elsewhere in the fortress.
Additional InformationI've had this happen in two separate worlds. It wouldn't feel so much like a bug if the farming & at-embark vegetation was not present, since that would just mean that underground oceans are as sterile as above-ground mountains.

completely vanilla install of DF, no utilities of any sort used.

My fortress (with only one modification of no w.g bandits) is settled upon a evil glacier but is officially on the tile of a frozen ocean with animals coming in adjacent. It is a death sphere primordial biome, hence plants die off but this report helps apply more explanation why my caverns are so desolate.

To help substantiate a bit more, from the muddy cavern seen on the fortress save it is actually two oceanic underground regions covering the whole area, which you can see from the world-save's legend mode.

The northmost unnamed cavern is inhabited by Lur the Vice of Fins (FB)while the main largest southern unnamed cavern stretching over many ocean tiles is inhabited by Sindur Standardhobble the Superior Crevice of Dominons (FB) as point of reference. Going through the list until you land upon and over the evil glacier also is useful for pinpointing where they are.
