Iseli Fastigiate Colorado Spruce
Iseli Fastigiate Colorado Spruce (Picea pungens 'Iseli Fastigiate')
Iseli Fastigiate Colorado Spruce (Picea pungens 'Iseli Fastigiate') is a striking, narrow blue spruce cultivar known for its tight, columnar habit and vivid silver-blue foliage. Selected by Iseli Nursery for its strong vertical form and uniform branching, this cultivar delivers bold structure and color in limited spaces where traditional blue spruces may be too wide.
Distinctive Features

The narrow footprint and formal shape make it an excellent choice for vertical accents or structured plantings where height is needed without lateral spread.
