To keep it simple, It is a Mystical plant that is said to not be able to regrow, dispite someone who is able to grow them, that being Avrusa Sarethi in Skyrim. The plant in Skyrim isn't as "rare" as the lore states, but can't be grown & appear much less frequent in Oblivion & are truly limited in that game as well. You use it to make potions which are useful considering you know how to make them. If not, you can always just sell them or the resulting potion for currency.
