A Type of Tree With Sharp, Pointy Leaves

If you've ever wondered why some trees have rounded leaves while others have sharp, pointy foliage, the answer may lie how they have adapted to their climate. Research indicates that trees with jagged, pointy foliage tend to lose more water, which prompts trees to draw more sap from their roots earlier in spring, says ABC Science. More sap means more nutrients, helping to jump-start the photosynthesis process. When you're choosing trees with sharp, pointy leaves for your landscape, consider the tree's U.S. Department of Agriculture plant hardiness zone rating and select trees that thrive in your climate.

  1. Hardy in USDA Zone 3

    • Several members of the fir genus (Abies spp.) have pointy, needle-like foliage. The white fir (Abies concolor) is grown in USDA zones 3 to 7 and is native to the Western U.S. This evergreen reaches heights to 130 feet in its natural habitat, but usually grows to 50 feet when cultivated. It has blue-green or dark-green foliage and is often used as a Christmas tree. The European larch (Larix decidua) is one of only a few deciduous conifers grown in cultivation. This European native grows to 65 feet and has green, needle-like foliage that grows in a spiral and turns copper, gold and orange in autumn. It's hardy in zones 3 to 6.

    Hardy In USDA Zone 5

    • Many holly trees have sharp, pointed foliage.

      Several members of the spruce genus (Picea spp.) have pointy, sharp foliage. The Oriental spruce (Picea orientalis) has dense, dark-green needles and a narrow canopy. Hardy in USDA zones 5 to 8, this evergreen grows slowly to 60 feet. Another spruce, the Colorado (Picea pungens), has fine, blue-green needles that emerge with a soft texture then harden over time. This North American native grows to 50 feet and is hardy in zones 4 to 7. The American holly (Ilex opaca) has glossy leaves with pointy tips. This broad-leaved evergreen grows to 50 feet and is hardy in zones 5 to 9. From fall through winter, this tree produces bright red berries that offer a colorful contrast to its dark, lustrous foliage.

    Hardy in USDA Zone 7

    • The Atlas cedar (Cedrus atlantica) has sharp, pointy foliage that adds an incense-like fragrance to the landscape. This evergreen is native to the Atlas Mountains, a range in northern Africa. It's hardy in USDA zones 6 to 9 and has silvery-blue needles. When cultivated, the Atlas cedar can grow to 65 feet. The Japanese red pine (Pinus densiflora) is hardy in zones 4 to 7 and grows quickly to 65 feet. Its rounded canopy is dense with aromatic, green needles. A cultivar, the tanyosho pine (Pinus densiflora "Umbraculifera") also has sharp, pointed foliage. This multi-trunked pine grows to 20 feet and makes an attractive accent plant.

    Hardy in Zone 9

    • The Canary Island pine (Pinus canariensis) has long, blue-green or dark-green needles. Native to the Canary Islands off the Spanish coast, this evergreen has an oval shape and grows to 80 feet. It's hardy in USDA zones 9 to 10. Fortunes osmanthus (Osmanthus × fortunei), a broad-leaved evergreen, has glossy, pointy foliage. Hardy in zones 7 to 9, this Chinese native grows to 20 feet. In spring, the Fortunes osmanthus produces inconspicuous but extremely aromatic white flowers.
