Stasis-field horticapsule

A stasis-field horticapsule was a type of container used to preserve plants, prolonging their blooming with a stasis field. One such device was used onboard Senator Padmé Amidala's J-type diplomatic barge, to keep a bhansgrek bush in bloom.

Behind the scenes
The stasis-field horticapsule was first mentioned in the 2018 reference book Star Wars: Complete Vehicles, a canon, updated re-release of the 2013 Star Wars Legends book of the same name.
