aka Treblitzensis which is an illegal Latinization of the plant's origin and Treblitsch which is a commonly-seen misspelling. Note that the RHS database uses this misspelling.
Picea omorika 'Treblitzsch' is a very compact, uniform silvery Blue-green ball of coarse, tiny needles that are radially arranged around the stem. Typical rate of growth in most areas is 1 to 2 inches (2.5 - 5 cm) a year, resulting in a silvery 2.5 foot (75 cm) ball after 10 years in the landscape.
'Treblitzsch' originated from cuttings taken from a witch's broom on a Serbian Spruce in Treblizsch Park, Belgern, Germany in 1977 and has been a very popular plant with conifer collectors and gardeners world-wide.
Because of its small size and uniform growth, this cultivar is an excellent choice for creating a focal point among plants of darker color and denser texture.
