Noteworthy Characteristics

Hypericum × inodorum is a fertile, hybrid, semi-evergreen shrub in which H. androsaemum was hybridized with H. hircinum. Hybrid plants generally grow to 3-5’ tall. They are noted for their beautiful foliage, showy flowers and decorative berries. Stalkless, ovate, opposite leaves (to 2” long) are aromatic when crushed. One-inch buttercup-yellow flowers in branched clusters bloom mid to late summer (July-September). Flowers differ from H. androsaemum in having petals conspicuously longer than the sepals and styles and from H. hircinum by having sepals that are persistent into the fruiting stage. Flowers are followed by showy coral pink fruits. The hybrid × inodorum as well as parent H. androsaemum differs from most other species in the genus by having fleshy, berry-like fruits rather than dry, dehiscent capsules. A number of × inodorum cultivars have been produced which primarily differ from each other in plant habit and fruit color.

Genus name comes from the Greek words hyper meaning "above" and eikon meaning "picture" in reference to the practice of hanging flowers from this genus above images, pictures or windows.

Hybrid name comes from the Latin word inodorus meaning "unscented" or "lacking fragrance".
