1. Appearance: Frohburg Spruce is a compact, dwarf evergreen tree with a pyramidal form. It typically grows slowly and maintains a neat, symmetrical shape. The needles are dark green and glossy, measuring about 1 inch (2.5 cm) long, and are arranged densely along the branches.

2. Size: This cultivar typically reaches a mature height of 8 to 12 feet (1.8 to 3 meters) and a spread of 6 to 8 feet (1.2 to 1.8 meters), making it a compact and manageable option for smaller landscapes or container plantings.

4. Sun and Soil Requirements: This tree prefers full sun to partial shade and thrives in well-drained soil with good moisture retention. It can tolerate a range of soil types, including loamy, sandy, or clay soils, as long as they are not overly wet or waterlogged.

5. Hardiness: Frohburg Spruce is cold-hardy and can tolerate freezing temperatures typical of its native range in northern Europe. It is suitable for USDA hardiness zones 3 to 7.

6. Landscape Use: Due to its compact size and attractive foliage, Frohburg Spruce is often used as a specimen plant in smaller gardens, rock gardens, or container plantings. It can also be used to provide evergreen interest in mixed borders or as a low hedge or screen.

Overall, Frohburg Spruce is a charming and versatile evergreen tree with a neat, compact habit and glossy dark green foliage. Its slow growth rate and cold-hardiness make it an excellent choice for gardeners seeking a low-maintenance tree for smaller landscapes or container gardens.
