This crystal-domed conservatory contains a second, galaxy-capable warp pad and Steven's own Diamond control panel similar to the one in Pink Diamond's Moon Base. The conservatory also functions as a sunroom and greenhouse, containing multiple potted rose and hibiscus bushes, gardening tools, a bench, a bean bag chair, and a bed for Lion.
After refusing the Diamonds' offer to stay on Homeworld to take his mother's place for her legacy, Steven warps back to the conservatory, where Connie is waiting for him. Steven can be seen using the control panel before the two exit the room. Later on, he follows Spinel to the conservatory only to see her crying over the fact that Steven have abandoned her. After Spinel's memories are recovered, they come back through the conservatory from Pink Diamond's Garden before going outside to fix everything happened.
Noticing Pink Diamond's zoo floating outside, Steven goes to the conservatory where he greets Jay-Ten and Wy-Six through the communication panel. The conservatory makes another appearance at the end of the episode, when Steven catches up to the Rose Quartzes right before they leave, and meets Amethyst after her trip to the zoo.
Steven's conservatory now has become home for many plants, including Cactus Steven, after he leaves Little Homeschool. Cactus Steven spend most of his time growing up here, however, the room is destroyed in an attempt of Cactus Steven to get outside to find Steven.
Steven walks in it once he exits the bathroom as he put a pink hexagonal wall on his friends so he ordered them not to him before he warped to Gem Homeworld.
Steven warps back from Homeworld to the conservatory.
It is seen as it it is unknown that Greg took the conservatory.
