Common Name: Iseli Fastigiate Colorado Blue Spruce
Description: The Iseli Fastigiate Colorado Blue Spruce (Picea pungens 'Iseli Fastigiate') is a striking, narrow-growing evergreen conifer prized for its vibrant blue foliage and strong vertical form. This cultivar has a naturally columnar habit, making it an excellent choice for small gardens, avenue planting, or as a structural feature in landscapes. Its dense, silvery-blue needles provide year-round colour and contrast beautifully with other plants. Thriving in well-drained soil and full sun, this spruce is drought and frost-tolerant once established. It requires minimal maintenance, making it a perfect option for formal gardens, narrow spaces, or adding vertical interest to mixed plantings.
