Paeonia suffruticosa ‘Kaoukamon’ is known for producing beautiful, dark maroon flowers with golden yellow stamens that emerge in mid-to-late spring, usually around mid-April, and last until mid-to-late June. The lightly scented blooms are smaller than other Tree Peony varieties but are a wonderful option as the focal point for the pollinator garden, where they’re sure to be visited by butterflies. This long-lived perennial will bloom best in full sun, but can handle part shade and moist - but not overly saturated - soils. Finely lobed foliage takes on a lovely color in the fall, ranging from golden yellows, to brilliant oranges and reds, making this Tree Peony a multi-seasonal favorite. The dark maroon buds and open blooms make excellent, dramatic additions to both the garden as well as to fresh cut flower arrangements.
Ruby Vase® Persian Ironwood is an excellent choice as a street tree or a showy specimen for small spaces. The habit is a narrow vase shape with tight upright branching. New leaves emerge in spring with an attractive red margin. The green Hamamelis-like foliage is clean and disease resistant all summer, turning lovely shades of yellow, orange and red in fall. The small reddish purple spidery flowers are borne in winter on the twigs, providing food for winter pollinators, and the bark of older plants is attractive patches of green, tan and gray.
'Vanessa' Persian Ironwood was chosen for its upright, columnar form. Parrotia 'Vanessa' has multi-season appeal, starting in winter and spring when attractive mottled bark is offset by small red spidery flowers. The oval shaped foliage emerges in spring with burgundy edges to the scalloped leaves. By summer the foliage is a bright green, taking on stunning shades of red, purple, orange and gold in fall.
Chinese Parrotia or Ironwood is a very rare large shrub or small tree which is highly endangered in its original Chinese habitats. Brought to England by Roy Lancaster, who received this clone from Mikinori Ogisu, the Japanese Botanist. Tim Brotzman, the Ohio nurseryman who is a leading expert on Hamamelis, provided this rarity to us. The green leaves in summer often have a striking purple margin. The fall color is really spectacular, in shades of red, pink and burgundy. Parrotia subaequalis is more compact than P. persica, but has more showy exfoliating bark as it matures. The infrequently appearing red filamentous flowers in winter are similar to Parrotia persica.
Coppertina® ('Mindia') Ninebark has light pink flowers in June, copper-colored foliage and good red fall color. It comes from Minier Nursery in France. Physocarpus is also wet site tolerant. Its peeling winter bark increases in showiness as Ninebarks age revealing layers of reddish to light brown inner bark, hence the common name of Ninebark.
Ginger Wine® Ninebark ('SMNPOBLR') is a showy native shrub, offering attractive flowers and foliage from spring through fall. The leaves start as shades of orange and red in spring, and mature to burgundy in summer. The fall color is a mix of red and burgundy. The delicate pinkish white flower clusters appear in late spring and are followed by attractive red seedheads. Physocarpus Ginger Wine® also offers winter interest with tan peeling bark on the older wood.
Summer Wine® ('Seward') Ninebark has pinkish white button-like flowers in June over a compact habit, and bright bronze-purple foliage. Physocarpus opulifolius Summer Wine® has a reddish-purple fall color and is also wet site tolerant.
Summer Wine® Black is the darkest Physocarpus on the market to date. The foliage is such a dark purple that it approaches black, and the delicate pink flower clumps really stand out in contrast when they appear in June. As the leaves mature throughout the summer, they take on some more bronzy tones, followed by showy reddish purple fall color. If desired, pruning is most appropriate right after blooming.
Sweet Cherry Tea™ (‘ZLEBiC5’) Ninebark has fine delicate leaves which emerge reddish orange and rapidly mature to deep purple. The flowers have dark pink buds which open to profuse pink clusters in June. The first heavy flowering period leads to the production of rather showy red fruit which feeds small birds. Fall color is shades of red and burgundy, and older plants have an interesting exfoliating bark. A Plants Nouveau introduction from Breeder David Zlasak.
Tiny Wine® ('SMPOTW') Dwarf Ninebark is a dwarf form of our native Physocarpus, with burgundy to bronze foliage. The flowers start opening in late spring, forming bunches of pink and white button-like flowers by June. The showy purple bronze summer foliage is followed by reddish purple fall shades. Does not need pruning, is deer resistant and wet site tolerant; Tiny Wine® is a big step forward for Physocarpus.
The red buds of 'Dorothy Wycoff' Japanese Pieris open to pale pink, highly fragrant flowers in March and April, serving as an important food source for early spring insects. Pieris japonica 'Dorothy Wycoff' is a compact form with dark green evergreen leaves.
'Flaming Silver' Japanese Pieris has dark green lustrous leaves with bright white margins. The new growth emerges in shades of red with pink margins, followed by fragrant white bells in pendant clumps in March and April. According to Michael Dirr, 'Flaming Silver' is a more vigorous grower than Pieris 'Variegata' and it is certainly more showy with wider white margins on the evergreen leaves.
‘Katsura’ Japanese Andromeda produces strings of white fragrant bells on pendent panicles in early spring. The new growth emerging in spring in vivid shades of bronze and red. The new leaves mature in summer to a lustrous green. The flower buds for the next year start developing in the summer and add to the winter interest by taking on shades of purple and red. Pieris japonica ‘Katsura’ is evergreen and should be protected from afternoon winter sun.
The fragrant white flowers of 'Mountain Fire' Japanese Pieris appear in March and April, with bright red new growth appearing on top of the shiny green, evergreen foliage almost all summer. The color of Pieris japonica 'Mountain Fire' make it look like a very refined Photinia.
Exclamation!™ ('Morton Circle') London Planetree is a hybrid selection by Dr George Ware at the Morton Arboretum. The controlled cross is between our native Sycamore and the Asian species. Platanus x acerifolia Exclamation!™ gets its name for its very upright pyramidal in the winter landscape. In addition to its very upright regular straight habit, Exclamation!™ is also resistant to both Anthracnose and frost cracking, so it makes a very versatile fast growing shade tree which tolerates a broad spectrum of site conditions. Introduced by Chicagolad Grows®.
'Flying Dragon' Hardy Orange (syn. 'Monstrosa') is a citrus that can actually be grown in the Northeast. The fruits are golf ball sized yellow-gold oranges in the fall that can be made into a very tart marmalade (lots of sugar needed). The deliciously fragrant white flowers are bourne on the deep green contorted, thorny stems in April and May. The twigs are ornamental for both structure and color in the winter. Just make sure Poncirus 'Flying Dragon' is not planted near play areas, as the thorns are significant.
Bush Cherry blooms in early spring, when its shrubby branches become covered with bright pink blossoms. The flower display is often followed by small red fruit which is attractive to wildlife. The fall color is a good yellow. Since Prunus jacqunemontii is a very early spring bloomer, it makes a great cut branch for early forcing. Another common name is 'Afghan Cherry'.
‘Chestnut Hill’ Cherry Hill is an introduction by the Morris Arboretum of Philadelphia. A more compact form of Prunus ‘Otto Luykens,’ Prunus laurocerasus ‘Chestnut Hill’ is named after the beautiful community in which it was found. Evergreen and rounded in habit, ‘Chestnut Hill’ thrives in shade as well as sun, and tolerates salty conditions better than most broadleaf evergreens. This dark green compact Cherry Laurel can be used as a foundation shrub or as a short dense hedge plant.
The dark green evergreen foliage of 'Otto Luykens' Common Cherry Laurel is compact, topped with highly fragrant white flowers in April and May. Prunus laurocerasus 'Otto Luykens' is an excellent broadleaf evergreen for shady locations with deer problems. It tolerates salt spray well. Introduced by Hesse Nurseries of Germany.
The first Cherry to bloom in the spring, 'Okame' has bright pink semi-double flowers which appear in late March to early April. Prunus x 'Okame' is a fine-textured cold hardy small tree that lights up the landscape at a time when we all need it. We first heard of this from Paul Meyer of the Morris Arboretum when it was introduced to the US, and it's still our favorite.
Prunus x yedoensis has soft pink flowers that open before the foliage emerges in early April. 'Yoshino' Cherry makes up the famous Cherry Blossom display in Washington DC along with 'Kwanzan' Cherry. Fall foliage is yellow to orange.
Prunus x yedoensis ‘Akebono’, meaning ‘daybreak’ in Japanese, is a lovely, small deciduous tree that provides multiple seasons of interest and attracts birds to the specimen or cottage garden. Delicate, light pink double blooms appear in early spring around late March to early April, filling the canopy with a soft mist of blooms that is akin to the pastel palette of an early spring morning sky. Small black fruits follow in the summer, that are a favorite of native and migrating bird species alike. Its glossy, dark green foliage achieves a rainbow of beautiful reds, oranges and yellows in autumn before dropping. Prunus x yedoensis ‘Akebono’ was introduced to the trade in 1925 by W.B. Clarke Nursery in San Jose, California. Seedlings of the cultivar were provided to the Washington D.C.’s Tidal Basin in the National Mall, where they intermingle amongst some 2,000+ other Yoshino Flowering Cherry trees in order to signify the cordial relationship between Japan and America. In fact, in Japan, the ‘Akebono’ cultivar is called ‘Amerika’.
