Notes
An attractive semi evergreen shrub with summer flowers. Leaves are shiny and become purple in cold weather. Tubular white flowers are ½" long and form in loose clusters. Occasional tip pruning encourages blooming until fall frost. Height 4-­‐6', spread 4-­‐
6' feet.
Shrub, growing to 5-­‐6' tall with fragrant pink flowers from late May to early June. Glossy foliage turns orange-­‐red in autumn.
Wide-­‐spreading, suckering multi-­‐stemmed shrub with many upright slender branches. Flowers white, anthers red, produced in July on cylindrical 8-­‐12" long, 2-­‐4" wide panicles; outstanding in flower. Fall color can be an excellent yellow, but seems to be strongly dependent on ideal environmental conditions.
Stunning and rare form of the European Black Alder with dark green leaves exhibiting a bold, irregular and intrusive light green almost yellow margin. This brilliant color combination is maintained well into summer before turning a golden yellow in fall. Reddish-­‐brown catkins are followed by attractive small, persistent winged nutlets. Neat cherry-­‐like bark extends seasonal interest. A broad, pyramidal tree especially useful for moist, sunny locations.
Large deciduous shrub or small tree, the very large bipinnate leaves with white-­‐margined leaflets. Flowers small, white in large panicles.

Notes
One of the best red-­‐flowering forms, better than 'Ruby Glow', but still more copper-­‐red than red. Fall colora rich orange-­‐red.
Large shrub or small tree reaching 15-­‐20' in height with a spread up to 10'; bark grey to brown; flowers open in August although buds are ornamental much earlier, by mid-­‐
summer, the individual flowers are creamy-­‐
white, fragrant, held in 6" long terminal panicles; fruit showy, a capsule with persistent sepals that mature from green to rose-­‐purple and remain showy well into the Autumn.
Hydrangea Pinky Winky™ is a unique Hydrangea with two-­‐toned flower heads in mid-­‐summer. The large, 12-­‐16 inches long flower heads emerge white, turn pink and continue to push new white flowers from the tip of the panicle. The flowers are held upright on strong stems and contrast nicely against dark green foliage. It blooms regardless of climate, soil, pH or pruning. A truly remarkable plant for the summer and autumn landscape.
Corymbs extremely large (to 1' across); blooms 10-­‐14 days later than 'Grandiflora'; flower heads are more erect on the stem and with a more nearly symmetrical radius, and are usually larger in total diameter than those of 'Grandiflora' grown under the same conditions (DS 9). According to Warren F. Broderick in NYFA Newsletter 12(3) this was originally found in the wild near Anna, Illinois and was named 'Annabelle' but since it corresponds to a described wild form it should be called H. arborescens f. sterilis (Torrey & Gray) St. John, when found in the wild (DS 664).
Large lime green flower clusters are produced in late summer and into early fall. Tough and cold hardy, Panicle Hydrangea flowers on new wood, so flower buds are never killed.

Notes
A Dutch selection that blooms several weeks earlier than most related types. Densely packed, terminal pyramidal heads of creamy-­‐
white flowers in early summer gradually turn a vivid dark pink as summer progresses. Young stems are rosy-­‐red. An easily grown, semi-­‐arching, extremely hardy shrub that requires moisture retentive, well drained soil.
Plants reach 3' in height and 6' in width; flowers and foliage are the size of the type.
Selected for attractive fall color of fiery orange with bright flashes of yellow; fruits red. This needs I. 'Raritan Chief' as a pollinator, which is I. verticillata X (I. serrata X I. verticillata); see Am. Nurs. September 15, 1997 (DS 474).
Selected to be a pollinator for 'Autumn Glow' a result of the same breeding program at Rutgers. Bob Simpson indicates it also pollinates Orton's hybrid 'Harvest Red' (DS 36).
Considered by many to be an improved form of 'Blue Girl' with more abundant, darker red fruit, and darker blue-­‐green lustrous foliage. Plants reach 15' in height, 10' in width; The best of the blue hollies for fruit production.
Broad-­‐spreading shrub reaching 15' in height with very silvery-­‐white branches and undulating growth. Leaves glossy, broad, dark green; fruits bright red, glossy and large. A distinctive plant.
Male clone suggested as a pollinator for female cultivars. Plant 25' tall, 20' wide, globe-­‐shaped, considered one of the best males for habit and foliage.
A vigorous and upright shrub when young that becomes arching and broad with age; can attain 18' in height. Foliage dark green, unusually glossy, remaining on the plant well into the fall. Fruit abundant, medium-­‐sized, glossy, bright red.

Notes
Plants reach 3'-­‐6' in height; northern type with small, smooth, and rather thin leaves borne on sturdy twigs on a rather upright plant. Fruits red, profuse, clumped and somewhat flattened. This has been a very weak grower for us; not a good cultivar for our area (MFH). Discovered in the wild in West Virgina and selected in 1955 for large fruits and upright form (American Nurseryman Feb. 2009)
Slightly hardier than the species with fragrant white flowers borne in late June that are twice as long asthose of the species. Fall color is a wonderful red-­‐purple, and often holds in southern Pennsylvaniawell into the winter. A vigorous grower reaching 6' in height, 12' in width; no serious pests or diseases.
LITTLE HENRY® is a dwarf version of the old favorite ‘Henry’s Garnet.’ It will grow in full sun to full shade, and requires little pruning or other maintenance. Less than three feet tall at maturity, Little Henry has fragrant white summer flowers that attract butterflies and hummingbirds. The green summer foliage changes to brilliant orange in the fall, giving Little Henry multi-­‐season appeal.
Shrub to 5' which has pink flowers from mid to early autumn. Plant it where is can drape over a wall or walk.
Plant a small tree, to 30'. Flowers dark yellow, much darker than those of M. 'Elizabeth', 3"-­‐4" across, opening before the foliage expands.
An upright tree with thick, leathery leaves and white flowers. The six tepals are tinged with magenta on the lower third and have a magenta stripe down the midrib.
A fast growing purple leaved shrub, with small white flowers appearing in early summer.

Notes
Emerging glowing golden yellow-­‐green spring foliage gradually changes to burgundy, which contrasts nicely throughout the growing season. Rounded clusters of creamy white flowers during late spring into early summer. Tolerant of a wide range of soil types and conditions, this easily grown native performs best in an open sunny location where its unique foliage is displayed to perfection.
Plants reach 2' in height; leaves smaller and less deeply lobed than the type, dark green.
Plants compact and fast growing, to 8-­‐10' tall and 3.5' wide. Leaves flush an attractive copper in spring and turn rich red in summer. A hybrid of P. opulifolius 'Dart's Gold' and 'Monlo'.
A new and improved Ninebark with neat, compact branching and fine deeply cut, dark crimson-­‐red leaves. A hybrid which combines the fine textrue and compact branching of Physocarpus 'Nana' and the dark foliage of DIABLO. This native has pinkish-­‐white, button like flowers in mid-­‐summer. It is very showy and extremely hardy.
Upright evergreen shrub of neat habit with stiff, spreading branches and dense rosette-­‐
like foliage; newgrowth bronze, changing to lustrous dark green at maturity. Flowers weakly fragrant, white, urn-­‐shaped,1/5" long, borne in 3" to 6" long slightly pendulous panicles, effective for 2 weeks in March and April.
This narrow form was chosen specifically for its strong upright branching and deep dark green needles.
A wide-­‐spreading tree with glaucous blue-­‐
green foliage; can reach 45' or more in height; cones heavily inyouth.
A cultivar of Scots pine selected at the Trompenburg Arboretum, Rotterdam, Netherlands for its silvery blue color. 'Bonna' is a rapid grower and will grow into a large, specimen-­‐sized tree with age. The soft blue needles contrast elegantly with the cinnamon-­‐
colored peeling bark.

Notes
This new variety was developed at Briggs Nursery. 'Western Lights' is a polyploid of 'R. 'Orchid Lights' (introduced 1986) and is sterile, so no seed heads are produced. 'Western Lights' boasts thicker, more lush foliage than 'Orchid Lights' and also has a slightly glaucous coloring. The larger flowers are orchid pink. Plants grow to 4' tall x 5' across.
Double, frilled pink flowers with sparkling silver centers effective in late April. Vigorous, wide-­‐upright; Dark green foliage in summer, becoming red-­‐mahogany in fall; some foliage retention all winter. University of Minnesota bud hardiness tested to -­‐18 degrees F.
Hardy to -­‐30 degrees F. Flowers are white and fragrant. Deciduous (DS 137). Developed by Albert Johnson and Harold Pellet of the University of Minnesota. 'White Lights' reaches 6' in height with a similar spread. Blooms are delicate pink in bud opening to show a faint pink tinge, which fades at maturity to white (DS 112).
Plants over 6' tall; hardy to -­‐25 degrees F.; very late blooming. Selected for especially lovely pink flowers.
To 5'; hardy to -­‐15 degrees F.; very early blooming; A.R.S. rating 3/3. Deciduous, open, upright shrub.

Shrubs with golden foliage grow to 3' high and wide and have white flowers in spring.
Small to medium-­‐size pyramidal-­‐oval tree. The mature landscape size is probably 30-­‐40', but in the wild it can attain 60'. Flowers 2 -­‐ 2 1/2" across, white with white filaments and orange anthers, borne in July. Leaves dark green, 1 1/2 -­‐ 3 1/2" long, assuming yellow, or red to dark purplish-­‐red tints in autumn. Bark flaky, ranging from soft grays and browns to orangish brown, that will often all intermingle on the same tree.
Similar to S. sinensis, distinguished by its shallowly furrowed bark and subglobose capsule, downy at base and abruptly beaked, with 4, not 2, seeds in each chamber.
Small, slender-­‐stemmed shrub reaching 6' to 8' in height. Bell-­‐shaped white flowers with highly reflexedlobes hang from the leaf axils in June and July; fruit is an obovoid, 1/3" long, grayish pubescent drupe which ripens in August and September.
The northern race of the American Snowbell, descended from a collection made in 1993 in a disjunct population near the Kankakee River in Kankakee County, Illinois. The parent plants are described as densely twiggy and only 4.5ft tall. The delicate, snow-­‐white flowers, like little bells with reflexed petals, festoon the branches in mid-­‐summer. A lovely shrub.

Notes
Somewhat similar to S. reticulata, but smaller (15-­‐20') with a more informal (multi-­‐
stemmed) habit, and finer texture throughout. The leaves and stems are smaller and finer. The flowers are creamy white and appear before those of S. reticulata in 3-­‐6" long panicles. Habit bushy, spreading and rounded. Bark often quite handsome, being sometimes similar to that of S. reticulata, or on some trees, may exfoliate in rich brown flakes or sheets.
Abundant flowers in May, followed by sporadic flowers throughout the summer. Because of the two or three sporadic flowerings, abundant glossy red fruit is produced that ripens in August, and persists on the plant until mid-­‐winter. Foliage thin-­‐
textured and pale turning pale yellow and orange-­‐red in fall. Growth habit upright with thin, wide-­‐spreading branches. The original plant is 10' tall, and 9 1/2' wide.
Full rounded habit with mature height apporaching 6' to 8' in height. Inflorescence ranges from 2 1/2" to 3 1/4" wide, and when not open is highly fragrant. Superior to V. carlesii and eventually may replace itin northern areas; more resistant to bacterial leaf spot, and roots much more readily from softwoodcuttings.
Plants have very dark, coriaceous leaves which are resistant to bacterial leaf spot, abundant inflorescences, hardiness, and a densely globose growth habit. The rugose, coriaceous leaves are are highly ornamental. The abundant, yellowish-­‐white inflorescences in May are effectively displayed above the dark green foliage. For several weeks in September and October the fruit becomes brilliant red as ripening advances to black at maturity.
A dwarf of the species, growing to 5' by 5'. Green foliage has pink tones when it first emerges. Flowers are white and fruits are blue-­‐black. Will grow in a wide range of soil types and under harsh growing conditions such as drought, salt and pollutants.

Notes
Selected for exceptional winter hardiness and prolific shiny red fruit. Plants reach 5-­‐6' in height developing a nicely rounded habit; creamy white flowers are effective in May and are followed by a profuse display of bright red fruit which is strong even without another pollinator in the area. Discovered in a batch of seedlings as the only survivor of a -­‐
30 F cold snap; plants are substantially hardier than 'Erie'.
Compact growth habit, dark green leaves that are resistant to leaf spot. Creamy white flowers and expanding pale green leaves appear together for a week in early May. The orange-­‐red fruit begins to ripen in early July and remains effective for 4 or more weeks, unlike the fruit of the species, which usually turns rapidly from red to black. Leaves variegated with yellow.
A seedling of 'Shasta' sharing all its attributes on a smaller scale, reaching only 5' in height, 8' in width in 17 years. Flower heads 3"-­‐5" across; fall color a dull reddish-­‐purple; drupes red maturing to black. Hardiness uncertain.
Abundant, 4-­‐6" wide inflorescences have sterile, marginal florets about 1 1/4 to 2" wide, and 5 to 15,1/2 to 1 1/2" wide inner florets dispersed among the fertile flowers; the flowers are followed in July bybright red fruits, which mature to black. Plants broad, horizontally branched, 6' high and 10-­‐12' wide.
Unusually compact, reaching only 2-­‐3 feet, with bright yellow leaves with green centers and dark red spring flowers.
Shrub with profuse display of soft pink flowers in late spring to summer. To 4' tall.
Taller and not as broad as 'Village Green' when mature. It grows twice as fast as 'Village Green' as a young tree, and 2-­‐yr. old trees are 2-­‐3 times taller. It has bright green foliage which turns bronzy-­‐red in the fall. Tolerant of atmospheric pollution and heat reflected from pavement, and grows well on city streets.

Notes
Plant 100cm tall, 135cm spread. Dense, erect to very slightly arching, much branched. Flowering stem thin, stiff, hairy (scabrous), 105cm long, Yellow-­‐Green Group 144B. Flower spike 16.5cm long, composed of very densely packed clusters. Individual bloom 1cm, stigma 1.5cm, stamens, 1.2cm, Violet-­‐
Blue Group 91A/B. Bright green mounds of delicately dissected foliage are topped in midsummer by 2' plumes of the purest white.
Plants reach 3-­‐4' in height producing long slender branches that arch and touch the ground at their tips; produces exceptionally heavy and showy crops of small lilac berries in fall.
Lou Emmons found a sport of 'Mary Stoker' growing in her garden, isolated it, ascertained that it was stable, and generously shared it with Seneca Hill Perennials. It is in full glory in late September to early October, producing masses of glistening gold-­‐centered white flowers that fade to charming shades of old rose. An old garden chrysanthemum, with a relaxed habit and spreading ways.
Clematis 'Ember' ™ is the first red herbaceous Clematis. Developed over a ten year period Ember is an inter-­‐specific cultivar. It neither favors the species integrifolia or heracleifolia but gathers on the best attributes of both. Flowers are a rich red in color, lasting a very long time. Blooms May until first frost possibly October. Seedheads are also a feature. Mature height: 12"-­‐15".
Pearly white 3-­‐4-­‐inch flowers smother the vine in June, and it blooms until late summer. It can scramble over a spring-­‐blooming shrub to extend its season of interest, or as Christopher Lloyd recommended, you can grow it up a pole or over a high wall so that you can experience a marvelous see-­‐through effect when viewed from below.
Flowers are large, vanilla-­‐scented, light-­‐pink, sometimes white if grown in shade.

Notes
Climbing to 24'; flowers rosy-­‐red to pinkish 2 -­‐ 2 1/2" in diamater, borne in May. Plumy seed heads areeffective in summer. New foliage is a pleasing bronze crimson color. Since it blooms so early it should be noted that the flower buds occur on the previous year's wood.
Climbing to 15'; flowers campanulate, butter yellow inside and out, 1 1/2" long; conspicuous seed headswith feathery styles.
Plants reach 3'-­‐6' in height; fall color yellow. Flowers are large, pink, fragrant.
Selected for its lustrous dark green foliage, compact habit and later flowering time, the flowers opening 10-­‐14 days later than those of the type.
Discovered in 1992 as a branch sport of 'Pink Spires' by Andy Brand of Broken Arrow Nursery, Hamden, CT. Flowers are significantly deeper and richer pink than any other selection to date, also fragrant. Foliage dark green; plants expected to be vigorous growers reaching 6'-­‐8' in height.
A low growing, dense plant with arching branches and small red fruit. The foliage turns bronze in the fall.
Showy, lavender flowers over thin, dark evergreen foliage that spreads.
Plants have wide leaf blades with a gold edge and lavender flower spikes. Mature height is
