Premna makes an excellent indoor bonsai. They do well indoors and can be kept outdoors in warm weather. They like a lot of direct sun but will do well with limited direct sun. More information below the photos.
In nature, they flower and produce fruit from spring to fall. They are valued for their smooth bark, and in nature with age they develop twisted deadwood. Leaf reduction is possible at a rate well beyond most species used for bonsai cultivation making this a favorite among serious bonsai hobbyists. Premna leaves and bark are widely used for medicinal purposes in many parts of the world. This is by no means an endorsement of its use for medicinal purposes, it is just part of the fascinating information I found about this fascinating tree Try a search to learn more about this amazingly interesting tree and its uses as a bonsai and beyond.
