A very cool hibiscus that adds an exotic touch to any garden, Japanese Lantern hibiscus has an unusual flowering habit — the red flowers dangle straight down on the ends on branches, resembling a lantern, constantly flowering if given bright light.
This plant performs best if the branches are allowed to ramble a bit, even planted behind other lower landscaping. The branches will protrude out and over other plants, and then dangle out beautiful red fringed flowers where they are easily seen. It can also be trained into a tree form for maximum “hanging lantern” effect.
