'Iseli Fastigiate' Blue Spruce
FamilyPinaceae
Picea pungens 'Iseli Fastigiata' is a Colorado blue spruce with a narrow columnar habit, known for its extremely bright, dense, and uniform silvery-blue foliage on short, upward-curving branches. Its very vertical and rigid habit, combined with a naturally structured form, makes it a strong architectural element, ideal for specimen planting, formal hedging, or as a vertical accent in a contemporary garden. Very hardy, wind and drought-resistant once well-established, it prefers full sun exposure and well-drained soil. Its moderate and regular growth allows for a neat shape without pruning, maintaining perfect form in all seasons. 'Iseli Fastigiata' combines verticality, intense color, and minimal maintenance, perfect for adding permanent structure to the landscape.
