Family: Clusiaceae
Native Habitat: western Europe, northern Africa

The genus Hypericum is both varied and widely distributed. The 400 or so species in the genus occur nearly world-wide, absent only in tropical lowlands, deserts, and polar regions. They vary from herbaceous annuals and perennials, to woody shrubs and small trees, and feature golden-yellow flowers, often quite showy. Commonly known as St. John's Worts, they usually come into flower in late spring or early summer. And why, you may ask, are they know as St. John's Worts? St. John's Day is a Roman Catholic feast day on June 24th that celebrates the birth of St. John the Baptist. Since Hypericums are usually in full bloom at that date, in medieval times the flowers were often gathered on St. John's Day and were thought to help ward off evil by being hung over windows and doors. ‘Wort' is an Old English word for ‘plant' that became commonly used in the names of herbs that had medicinal properties, which brings us to St. John's Wort most well-known use. Common St. John's Wort ( H. perforatum ) was known to have medicinal properties as early as by the ancient Greeks. It was used as a component in universal panaceas through the centuries. Today it is widely known as an herbal treatment for major depression although its efficacy is controversial and unproved.

'Albury Purple' is a selection distinguished by it's wonderful purple-tinged foliage. The bright golden-yellow flowers with prominent stamens begin in early summer and last for several months and contrast wonderfully with the purple foliage. An impressive fruit display soon follows. The small berries begin yellowish then gradually change to red, purple, and finally black. Different colored berries are often present in the same cluster.

This is an adaptable, easy-to-grow shrub. Fairly drought tolerant, its only dislike is with excessively poorly drained soils. Here in northern Indiana it is a “die-back” shrub. With a broad spreading form, it will grow to about 2 ft. tall in summer. It is semi-evergreen in warmer climates and does hold its foliage quite late here. There is no fall color to speak of. In winter the stems are killed back to the central crown so you will need to prune down to live wood in the spring, after which it will quickly regrow.
