Botanical Cruisers are ships with bio domes that serve as civilian transports, possible vacation spots, or are used as greenhouses for specialty food or plant-matter production.
Newly-inaugurated President Laura Roslin visited the sublight-capable Botanical Cruiser while gathering a caravan from surviving civilian ships surrounding the colony of Caprica. There she meets with the ship's captain and crew to determine their needs, and also meets a young girl named Cami and her grandmother who are traveling on the ship with many others, bound for Caprica City. However, the ship that Roslin visits lacks an FTL drive, and the FTL capable part of President Roslin's caravan of refugee ships are forced to leave Botanical Cruiser and many other sublight ships behind when Cylon Raiders discover and attack the caravan. It is destroyed along with the other left behind sublight ships (Miniseries).
Several months following the escape from New Caprica, it is successfully escorted to the algae planet through a dangerous star cluster on the fifth and final jump, although it appears the biota did not fare so well in the presence of so much ionizing radiation (The Passage).
It would survive the Battle of the Ionian Nebula and later jumped away when the Rebel baseship jumped in ahead of the sewage recycling freighter Demetrius (He That Believeth In Me, Guess What's Coming to Dinner).
The vessel would still remain with the fleet until the finding of Earth, where it, along with the other remaining vessels in the fleet would be sent into the sun. It is the last vessel seen by Adama as his Viper exits the launch tube (Daybreak, Part II).
