This document provides an overview of the Weeping Japanese Red Pine (Pinus densiflora ‘Pendula’), detailing its characteristics, growth habits, and care requirements. The tree is noted for its picturesque silhouette, with a crooked trunk and reddish-orange peeling bark. It thrives in full sun and well-drained, slightly acidic soil, and is suitable for USDA hardiness zones 3B through 7A2. The document also highlights its moderate drought tolerance, pest resistance, and potential issues such as needle blight and rusts. Additionally, it mentions several cultivars and their unique features. Original publication date October 1999.

This publication provides an overview of Abies firma (Japanese Fir), a slow-growing, evergreen tree native to Japan and suitable for USDA hardiness zones 5B–8B. Characterized by its dense, pyramidal crown and stiff, dark green needles, Japanese Fir reaches 20–30 feet in height and 10–15 feet in spread. It is valued for ornamental use, as a Christmas tree, and for screening purposes. The species thrives in acidic, well-drained soils under full sun and demonstrates high drought tolerance, making it an excellent candidate for southeastern landscapes. Japanese Fir requires minimal maintenance, exhibits resistance to pests and diseases, and has little invasive potential. Propagation is primarily by seed.

A handsome evergreen for specimen planting where it will not be crowded since the tree looks its best when branches are left on the tree to the ground. This shows off the wonderful weeping form with lower branches spreading about half the height. Spread, height and tree form is somewhat dependant on how the tree was trained. It can probably reach 30 to 40 feet tall if it was staked. Allow plenty of room for branches to spread.

A handsome evergreen with blue, bluish-green or light green foliage, 'Glauca' atlas cedar is perfect for specimen planting where it can grow without being crowded since the tree looks its best when branches are left on the tree to the ground. This shows off the wonderful irregular, open pyramidal form with lower branches spreading about half the height. It grows rapidly when young, then slowly, reaching 40 to 60 feet tall by 30 to 40 feet wide. The trunk stays fairly straight with lateral branches nearly horizontal.

With its pyramidal shape, soft grayish-green (or blue) needles and drooping branches, this cedar makes a graceful specimen or accent tree. Growing rapidly to 40 to 50 feet tall and 20 to 30 feet wide, it also works well as a soft screen. The trunk stays fairly straight with lateral branches nearly horizontal and drooping. Lower branches should be left on the tree so the true form of the tree can show. Allow plenty of room for these to spread. They are best located as a lawn specimen away from walks, streets, and sidewalks so branches will not have to be pruned. Large specimens have trunks almost three feet in diameter and spread to 50 feet across.

This is a large stately evergreen, with a massive trunk when mature, and wide-sweeping, sometimes upright branches (more often horizontal) which originate on the lower trunk. Allow plenty of space for proper development. Dark green needles and cones, which are held upright above the foliage, add to the impressive appearance. Young specimens retain a pyramidal shape but the tree takes on a more open form with age. Like most true cedars, it does not like to be transplanted, and prefers a pollution-free, sunny environment.

This native North American pine is usually seen as a scrubby tree, capable of reaching 100 feet in height but more often seen 15 to 40 feet tall, with a slow growth rate. The supple, evergreen leaves and the plant's ability to thrive in almost any soil make Sand Pine a good choice for use as a Christmas tree, with proper shearing. The 2 to 3.5-inch-long, spiny cones persist for quite a while on the tree, often becoming embedded in the wood of the twigs.
