I was wondering if there has been any discussion about how long the growing seasons are for the various commecially grown plants in Morrowind and in Vvardenfell itself.

IIRC, the game mechanism respawns plants you pick every 30 days, but is that consistent with info that Bethesda may have published or with in-game dialog?

Are there harvestable plants in the MW universe that have respawning cycles different from that of the game's 30 day cycle?
