MOE Pines in the Arboretum Pines are probably the best known of the conifers native to The genus Pinus is divided into hard and soft pines based on the northern hemisphere. They occur naturally from the up the hardness of wood, fundamental leaf anatomy, and other lands in the tropics to the limits of tree growth near the Arctic characteristics. The soft or white pines usually have needles in Circle and are widely grown throughout the world for timber clusters of five with one vascular bundle visible in cross sec and as ornamentals. In Minnesota we are limited by our cli tions. Most hard pines have needles in clusters of two or three mate to the more cold hardy species.

Pinus Parviflora Japanese White Pine1 Edward F
Fact Sheet ST-470 October 1994 Pinus parviflora Japanese White Pine1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION Japanese White Pine creates a striking landscape element wherever it is used (Fig. 1). Often seen as a dense, conical form when young, Japanese White Pine develops into a 25 to 50-foot-tall, graceful, irregularly- shaped tree, with an equal or greater spread, and a broad, flattened canopy. The 1 to 2.5-inch-long needles are stiff and twisted, forming blue/green tufts of foliage at branch tips, and creating an overall fine texture to the tree’s silhouette. The brownish-red cones are one to four inches long and persist on the tree for six to seven years. GENERAL INFORMATION Scientific name: Pinus parviflora Figure 1. Young Japanese White Pine. Pronunciation: PIE-nus par-vih-FLOR-uh Common name(s): Japanese White Pine Texture: fine Family: Pinaceae USDA hardiness zones: 4B through 7A (Fig. 2) Foliage Origin: not native to North America Uses: Bonsai; screen; specimen; no proven urban Leaf arrangement: alternate; spiral (Fig. 3) tolerance Leaf type: simple Availability: somewhat available, may have to go out Leaf margin: entire of the region to find the tree Leaf shape: needle-like (filiform) Leaf venation: parallel DESCRIPTION Leaf type and persistence: evergreen; fragrant; needle leaf evergreen Height: 25 to 50 feet Leaf blade length: 2 to 4 inches; less than 2 inches Spread: 25 to 50 feet Leaf color: blue or blue-green; green Crown uniformity: irregular outline or silhouette Fall color: no fall color change Crown shape: spreading; pyramidal Fall characteristic: not showy Crown density: dense Growth rate: slow 1. -
Rutgers Home Gardeners School: Dwarf Conifer Presentation
Dwarf Conifers and Other Dwarf Ornamentals: Their Use in the Landscape Why Dwarf Conifers and Dwarf Ornamentals? Long lifespan in the garden Take up little space Management/Maintenance is done with both feet on the ground Many species live in pots 1 Attributes of dwarf conifers in containers They are easily transported from one part of the garden to another Evergreen forms provide much needed color/texture and form in the winter landscape. Some of the larger dwarfs end up bonsaiing themselves naturally in pots due to root restriction Once established, they require the moisture requirements of the rest of the garden Growing requirements: Light Full sun to half a day is required If only half a day you can choose between morning and afternoon. Note: With dwarf flowering ornamentals, they prefer more than half a day of sun. 2 Growing requirements: Water With permanent plantings in the garden, water twice a week for the first 4 to 6 weeks, after the initial time period, drop back to once a week. With pots and container gardening, water twice a week for the first 4 to 6 weeks and once a week thereafter through November 15 through the 30th. Note: containers will need to be checked for water needs throughout the winter. Growing requirements: Fertilization With dwarf conifers, they can go without fertilizer every other year. Application is early April: soil has to warm up so the fertilizer is used. Use an organic fertilizer like Hollytone. With all other dwarf ornamentals, feed in early April, Hollytone or Plant tone for example. -

Thirty-four Styphnolobium japonicum varieties were analyzed using sequence-related amplified polymorphism (SRAP) markers, to investigate genetic variation and test the effectiveness of SRAP markers in DNA fingerprint establishment. Twelve primer pairs were selected from 120 primer combinations for their reproducibility and high polymorphism. We found a total of 430 amplified fragments, of which 415 fragments were considered polymorphic with an average of 34.58 polymorphic fragments for each primer combination. The percentage of polymorphic fragments was 96.60%, and four primer pairs showed 100% polymorphism. Moreover, simple matched coefficients ranged between 0.68 and 0.89, with an average of 0.785, indicating that the genetic variation among varieties was relatively low. This could be because of the narrow genetic basis of the selected breeding material. Based on the similarity coefficient value of 0.76, the varieties were divided into four major groups. In addition, abundant and clear SRAP fingerprints were obtained and could be used to Genetics and Molecular Research 15 (2): gmr.15027837 ©FUNPEC-RP www.funpecrp.com.br R.X. -

Invasive Plant List
NON-NATIVE INVASIVE PLANTS OF ARLINGTON COUNTY, VIRGINIA While up to 40% of the plants found in a typical urban environment are non-native species, a relatively small number of these “alien” plants are known to represent an ecological threat to the natural environment (parks, woodlands, and backyards). Known as “invasive species”, these non-natives will spread from urban plantings into natural areas, eliminate native species, alter natural plant communities, and degrade the environment. The following plants have been documented as invasive species in Arlington. Known invasive plant species should not be planted as part of any Arlington County sponsored project. This list will be periodically reviewed by the Invasive Plant Coordinator (DPR) and updated by Version (date).
