        Location
        East Asia originally. Now widely distributed around the world; introduced into north America
        before 1600.

        Culture
        A particularly vigorous and durable shrub, the rose-of-sharon will grow in many soil types, but
        prefers deep, fertile, well drained situations. Depending on soil quality, may benefit from fertilizing.
        Cut back hard in spring if desired to control size and produce larger blooms. Usually grows with no
        attention at all, and probably does better that way!
        Light: Sun or high, shifting shade. In hot climates, benefits from afternoon shade.
        Moisture: Average.
        Hardiness: USDA Zones 5-8.

        Propagation: Cuttings, layering, grafting. Does not grow true from seed.
        Description
        A long blooming, upright, deciduous shrub, 6'-10' by 3'-5'. Distinctive
        leaves, arranged alternately, have three deep lobes and are toothed.
        They are usually bright or dark green. Flowers may be single or
        double and come in white, blues, purples, and pinks. Some have a
        pronounced crimson base. They are usually about 3" in diameter and
        flared, like most mallow flowers. Overall texture of shrub is coarse.

        Usage
        Most commonly used in a mixed shrub border or in a bed or planting group for its tall, upright shape
        and summer color. Can also stand alone as a specimen.

Features
Large, showy summer flowers.

Ilex x altaclarensis
Dahoon holly : Ilex cassine
Georgia holly : Ilex longipes

California privet : Ligustrum ovalifolium

Sweetgum : Liquidambar styraciflua

Tuliptree : Liriodendron tulipifera

Mountain laurel : Kalmia latifolia

Magnolia : Magnolia soulangiana

Japanese flowering crab : Malus floribunda
Without a doubt the crab or malus floribunda is unrivalled in its springtime bloom. Because
the clusters of five-petaled 1- to 1 1/2-inch flowers open almost simultaneously, the show of the different
colored buds and blossoms create a remarkable sight before the leaves unfold. In the garden these small
deciduous trees are best displayed singly or in small groupings.

Growing up to 25 feet with a spread of 15 feet or more,the Japanese crab apple is a dependable bloomer and
fruits heavily every year. It is rounded in form and densely branched making it somewhat more distinctive than
other flowering crabs because of its fuller form. The flower buds of the japanese flowering crab are a deep red
but when fully open the fragrant flowers are rose-colored fading to pale pink. The yellow-and-red fruit, 3/8 inch
across of the malus floribunda ripens from late summer through fall. The pointed oval leaves are 2 to 3 inches
long and have sharply toothed edges. Young branches of this flowering crab are somewhat fuzzy and quite
reddish. Easily grown from seed and blooming while fairly young, the Japanese flowering crab grows
vigorously in container plantings as well as in the landscape.

The Japanese crab apple grows successfully in Zones 4-9. A location with full sun is best. Plant in moist but
well-drained slightly acid soil enriched with organic matter such as peat moss, compost or leaf mold. Plant in
spring or fall. Feed in the spring with a balanced fertilizer such as 10-10-10. Mulch young plants with compost,
or other organic material to keep soil cool, moist and weed free. You may prune young trees to develop more
open branching. Older japanese flowering crabs that have become dense should have some of the branches
removed for better appearance and to improve light penetration. Prune after flowering. Malus floribunda can be
propagated from cuttings with a little practice. Seeds from malus floribunda germinate easily and in high
percentages.

Common apple : Malus pumila
Domestic apple : Malus sylvestris

Metasequoia glyptostroboides

White mulberry : Morus alba
Red mulberry : Morus rubra

Nothofagus procera

Eastern hophornbeam : Ostrya virginiana

Sourwood : Oxydendrum arboreum

Eastern sycamore : Platanus occidentalis

Carolina Poplar : Populus x canadensis-http://www.msue.msu.edu/msue/imp/modop/00002015.html
rdiness Zones: 2 to 6
Height: 50 ft Spread: 35 ft Form: rounded
Type: deciduous tree
Annual Growth Rate: more than 18 inches

Comments: This hybrid poplar grows quickly but has
significant bad habits. It should not be grown near sewer
lines and it is susceptible to canker diseases. Poplars
are problem-prone plants that require more care than other
trees.

Cultivars:
   'Imperial' - A male clone, attains a roughly pyramidal
     shape with a height of 60 feet and a spread of 35
     feet.
   'N.E. 308' - A narrow, columnar form reaching a height
     of 55 feet but spreading only 22 feet.
   'Nor'easter' - This clone is a sterile female so will
     be seedless. It is listed as being more disease
     resistant than other poplar cultivars. It is a
     rounded tree reaching a height of 75 feet and a width
     of 40 feet.
   'Robusta' - This cultivar is also seedless and forms an
     oval crown on a tree about 50 feet tall and 35 feet
     wide.

Bigtooth aspen : Populus grandidentata
Lombardy poplar : Populus nigra
Black Cottonwood : Populus trichocarpa-http://www.msue.msu.edu/msue/imp/modop/00002065.html
        Hardiness Zones: 5
        Height: 75 ft   Spread: 35 ft Form: oval
        Type: deciduous tree
        Annual Growth Rate: more than 18 inches

         Comments: Poplars are problem-prone trees that require
         more care than other trees. This one is no different.
         Profuse production of cottony seed from female plants can
         be a nuisance. The tree also has brittle wood so storm
         damage should be expected. Black Cottonwood is native to
         wet areas and so will tolerate wet soils. The fall color
         is yellow. The opening buds have a pleasing fragrance.

Douglas-fir : Pseudotsuga menziesii http://www.forestry.auburn.edu/coops/sfnmc/class/dfir.html
                                                       http://www.orst.edu/instruct/for241/con/dfgen.html
       ouglas-fir is the name of an entire genus of trees that contains six species--two native to North America and
       four native to eastern Asia. Because of its similarity to other genera, Douglas-fir has given botanists fits. It
       has, at various times, been called a pine, a spruce, a hemlock, and a true fir. In 1867, because of its
       distinctive cones, it was given its own genus--Pseudotsuga--which means false hemlock. The hyphen in the
       common name lets us know that Douglas-fir is not a "true" fir--that it's not a member of the Abies genus.
       Only one Douglas-fir is native to the Pacific Northwest, and it's by far the most important member of the
       entire genus. Its common name is identical to that of the genus, reflecting its importance. Douglas-fir
       (Pseudotsuga menziesii) is Oregon's state tree.
