Alberta spruce (or Picea glauca, also known as White spruce or Canadian spruce) is native to North America. It is a coniferous, evergreen tree that grows in a pyramidal form. With deep green, needle-like leaves and brown cylindrical cones, the Alberta spruce is sometimes used as a Christmas tree. A dwarf cultivar, 'Conica', is popular as a garden plant. Fast Growing Trees Nursery also carries elegant dwarf Alberta spruce spiral topiaries. Dwarf varieties are designed to be smaller than the parent tree, and are often used as vertical accent specimens within the landscape. Dwarf varieties are also suitable for growing in containers. Dwarf Alberta spruce makes an excellent foundation planting. Remember to leave three to four feet from the center of your planting hole to allow for its growth. The Dwarf Alberta spruce typically grows to a height of 10 to 12 feet, but this slow-growing tree takes more than 25 years to completely mature, making it great decor when potted, because it will not outgrow your porch, or sunroom, or landscape any time soon. Alberta spruce thrives in zones 3 through 8. This hardy tree can withstand high winds, cold temperatures, as well as periods of heat and / or drought. Alberta spruce prefers full sun and appreciates well-drained soil, but it can tolerate some shade. Since it is evergreen, the spruce will keep its beauty and form year-round. When other deciduous trees have lost their leaves, the Alberta spruce will still be attractive in your landscape.
