Here's another profile of one of our favorite trees:
Sciadopitys verticillata (Japanese Umbrella Pine)
Why we love it: Long glossy needles and slow to grow, this tree is like no other evergreen.
Hardiness Zones: 4 to 8
Height: 20 ft to 30 ft Spread: 15 ft to 20 ft
Type: evergreen tree
Annual Growth Rate: 6 inches
Prefers full sun to partial shade. Likes moist, acidic, well-drained soil. Slow growing tree, but worth the wait.
Long glossy needles give this tree a distinct look, different than any other evergreen.
The Japanese Umbrella Pines are slow-growing enough that they don't need pruning. But this exchange on Gardenweb should reassure anyone whose tree got clipped.
