Monrovia Announces New Plants for 2010

2010 new plant introductions

Monrovia, the leading grower of premium plants, is introducing 40 varieties for 2010 that are new to the market, including 16 exclusive and six semi-exclusive introductions. Under the guidance of Nicholas Staddon, director of new plants, Monrovia has become a leader in the acquisition, trialing and promotion of new plant varieties. “We partner with breeders and plant hunters like Dan Hinkley to uncover improved varieties. Our emphasis is on plants that are healthier, hardier and easier to care for,” he explained.

Monrovia’s latest offerings include two new varieties of the Itoh Peony Collection, five selections added to the Dan Hinkley Collection, three colorful Barberries from Ohio plantsman Jim Zampini and the world’s first prostrate Camellia. Below are details on 23 of the stars for 2010, alphabetical by botanical name.

Beesia deltophylla

USDA Zone 6 – 8
Excellent evergreen ground cover from the Dan Hinkley Collection. When Dan collected the seeds in China years ago, he was immediately intrigued by the species, but frustrated by the virtual absence in any reference book. Sure to be hugely popular when gardeners see its exceptional shiny, green to gunmetal blue, heart-shaped leaves and pretty white star-shaped flowers in mid to late spring. A fuss-free filler for shady understory spaces or a woodland garden. This slow-growing perennial will reach 18 to 24 inches tall and wide. Prefers dappled shade and moist, rich soil.

Golden Ruby™ Barberry
Berberis thunbergii ‘Goruzam’ P.P. #16203

USDA Zone 4 – 8
A beautiful, slow-growing compact plant with striking coral-orange foliage accented with a golden margin. Makes a great landscape plant for mass plantings or an eye-catching color contrast. Its compact growth habit, only two feet tall and wide, makes this a low maintenance selection. Prefers full sun. Deciduous. Another fantastic dwarf Barberry from Ohio plantsman Jim Zampini.

Green Hornet™ Barberry
Berberis thunbergii ‘Grhozam’

USDA Zone 4 – 8
A very compact, low-growing Barberry, sporting emerald green foliage with teal blue undersides. Its striking orange-gold fall color works well when defining a walkway or as a mass planting in a larger area of the garden. One and one-half feet tall and three feet wide. Full sun. A marvelous selection from Ohio plantsman Jim Zampini.

Pygmy Ruby™ Barberry
Berberis thunbergii ‘Pygruzam’

USDA Zone 4 – 8
Shiny, deep red leaves cover the naturally dense, globe-shaped shrub. With no trimming required to maintain its neat, dwarf habit, this makes a fine low-maintenance mass-planting, low border or accent. Deciduous; one and one-half feet tall and two feet wide. From the renowned plantsman Jim Zampini, another easy-care dwarf Barberry.

Golden Triumph™ Boxwood
Buxus microphylla ‘Golden Triumph’ P.P.A.F.

USDA Zone 4 – 9
A low-growing, compact Japanese Boxwood, rarely reaching above three feet tall in 10 years. Shiny green foliage with showy golden-yellow margins adorn this very hardy Boxwood variety, creating a great contrast plant in the garden. This slow grower works well in foundation plantings, or to create a unique pattern or framework in a formal garden. Full sun or dappled shade. Performs well in the heat.

Marge Miller™ Camellia
Camellia sasanqua ‘Marge Miller’

USDA Zone 7 – 10
Although presented in the form of a patio tree or staked to three feet tall, this Australian introduction is the first prostrate Camellia in the world. It makes a superb ground cover, spilling over walls or even from a hanging basket. When trained on a stake or wall, it will cascade down for a lovely weeping shape. Full, soft pink flowers appear in fall along the stems against the deep-green, glossy foliage. Prefers filtered sun.

Clematis Vancouver™ Starry Nights
Clematis x ‘Starry Nights’

USDA Zone 4 – 9
Clematis continue to captivate us and Vancouver Starry Nights is no exception. Sporting large, eight-inch fuchsia rosy-pink flowers that grow darker towards the center, with age the flowers become paler. However, the mid-rib of the bloom continues to be very colorful. This mid-rib is “dusted with gold,” which shimmers in direct sunlight. Will reach 10 feet. Full sun.

Chinese Fairy Bells
Disporum cantoniense ‘Green Giant’

USDA Zone 6 – 9
A new addition to Monrovia’s Dan Hinkley Collection, this magnificent evergreen perennial was found and named by noted plant explorer Dan Hinkley in Sichuan Province, China. Its bamboo-like shoots emerge in shades of pink, white and green, maturing to deep green. Fragrant, creamy-white flowers unfurl like nodding bells with new growth each spring; flowers are followed by glistening black fruit in fall. Four to six feet tall, three feet wide. Partial to full shade; needs moderately moist soil. A perfect container plant.

Surprise Bouquet™ Yucca
Hesperaloe parviflora ‘Surprise Bouquet’

USDA Zone 5 – 11
The combination of Red Yucca and Yellow Yucca in the same container creates tall spikes of deep rose-pink, yellow and yellow-orange flowers almost year-round, and the nectar-filled blooms are irresistible to hummingbirds. An evergreen perennial often used with other desert-like plants. Full sun. Moderate grower to three to four feet tall and wide; flower stalks to four to six feet. It is also great as a container plant.

James Fleming Hibiscus
Hibiscus moscheutos ‘James Fleming’ P.P.A.F.

USDA Zone 4 – 10
This groundbreaking improvement, from the breeding program started by the late Fleming Brothers, produces maroon-tinted foliage.

Works well as a single specimen, multiple planting, or free-form hedge. This evergreen has a nice compact form. Eight to 10 feet tall and wide. Full sun.

Antonow’s Blue Honey Bush
Melianthus major ‘Antonow’s Blue’

USDA Zone 7 – 12
From Monrovia’s Dan Hinkley Collection is this selected form of the Giant Honey Bush with evergreen, powdery blue, highly textural foliage along stems to eight feet. In late spring, spikes of deep burgundy, nectar rich flowers will attract numerous bird species to the garden. This represents one of the hardiest clones of this species, appropriate in Zones 7 and higher. Prune hard after flowering to rejuvenate from the base. Full sun and sharp-draining soils. Plant the crown three inches below grade to increase general hardiness in colder climates.

Fairy Magnolia™ Blush
Michelia x ‘MicJUR01’ P.P.A.F.

USDA Zone 8 – 11
Bred by renowned New Zealand breeder Mark Jury, Fairy Magnolia Blush is an upright, bushy shrub, reaching 10 to 13 feet high and 8 to 10 feet wide. With masses of blushed lilac-pink flowers blooming late winter to mid-spring, it is excellent as a specimen plant or hedge plant, to take advantage of its naturally compact habit. Position near doorways or under windows to enjoy the fragrant blooms. Partial sun to dappled shade.

Windcliff Pachysandra
Pachysandra axillaris ‘Windcliff’

USDA Zone 8 – 10
Collected by Dan Hinkley on LongShou Shan in Sichuan Province in the summer of 2006, this rarely encountered species of Pachysandra offers distinctive evergreen foliage and noticeably fragrant white flowers in early spring, repeating again in autumn. An ideal and unique groundcover, just four to six inches high, for shade or sun in Zones 8 – 10. A fantastic addition to Monrovia’s Dan Hinkley Collection.

Itoh Peony Collection

Those who admire the colorful and exotic flowers of tree peonies, but prefer the perennial growing cycle of herbaceous Peonies, will love the Itoh Peonies, also known as intersectional hybrids. Until recently, these great plants were slow to propagate and far too expensive for most gardeners — some divisions were selling for $1,000 each. But, thanks to modern tissue culture, the plants are much easier to propagate in greater numbers, thus significantly reducing the cost to consumers. Last year Monrovia introduced four Itohs and for 2010 is offering two exclusive varieties.

Itoh peonies resemble tree peonies with a domed, vigorous growth habit and large double flowers with disease-resistant lacy, dark green foliage. After the flowering cycle, gardeners will enjoy the handsome bush for the remainder of the season. Once established, Itoh Peonies have an extended blooming period, with as many as 50 blooms in a single season due to their ability to produce primary and secondary buds. They are excellent in cut flower arrangements. They will grow two to three feet tall and wide and continue to improve with age.

Itoh peonies resemble tree peonies with a domed, vigorous growth habit and large double flowers with disease-resistant lacy, dark green foliage. Like herbaceous peonies, the Itoh hybrids are winter dormant providing decades of enjoyment in the garden. Itoh peonies can provide up to 50 blooms in a single season due to their ability to produce primary and secondary buds. They will grow two to three feet tall and wide. They offer an increased color range, greater vigor, and excellent resistance to peony blight (botrytis paeoniae).

Pink Double Dandy Itoh Peony
Paeonia (Itoh) x ‘Pink Double Dandy’

USDA Zone 4 – 8
The large, semi-double to double flower measures up to six inches and is held on strong stems above a compact mound of 24 to 30 inches tall and wide, dark green foliage. As the flower matures, the dark lavender pink petals slowly fade to a soft pink, revealing a cluster of yellow stamens in its center. The flower is lightly fragrant. Prefers full sun to dappled shade. Hybridized by Don Smith, a leading Itoh Peony breeder.

Yellow Doodle Dandy Itoh Peony
Paeonia (Itoh) x ‘Yellow Doodle Dandy’

USDA Zone 4 – 8
The large, double flower, measuring seven to eight inches, is spectacular: masses of clear yellow petals form a perfect flower with a light and very pleasant fragrance. Blooms are held on strong stems just above a compact mound of dark green, trouble-free foliage. Plant is very hardy and prefers full sun to dappled shade. Excellent dark green foliage, it lasts well into autumn. Ideal for cut flowers. Hybridized by Don Smith, a leading Itoh Peony breeder.

Charisma® Nuttall Oak
Quercus nuttallii ‘MonPowe’

USDA Zone 5 – 9
This native tree with outstanding maroon to chocolate-colored foliage and stems was discovered by Monrovia Craftsman Marty Powe. New spring growth remains well into summer before turning a deep green color. Branching habit is somewhat open with the deeply lobed foliage exhibiting striking red fall color. This shade tree grows well in acid or poorly drained soils and requires minimal pruning. Full sun. Deciduous. Moderate growth to 60 feet tall and 50 feet wide.

Southern Moon™ Yedda Hawthorn
Rhaphiolepsis umbellata ‘Rutrhaph1’ P.P.A.F.

USDA Zone 7 – 10
A significantly improved selection from noted plantsman Dr. John Ruter with the University of Georgia. Close to a decade of evaluation has shown this plant to exhibit exceptional disease resistance combined with a compact, self-mounding habit remaining just four to five feet tall, unlike Rhaphiolepsis umbellata ‘Minor’. Dark green, glossy foliage and wavy margins add interest. Abundant white flower display appears in spring prior to emerging new growth. Excellent for foundation plantings. Southern Moon is a great choice for anyone seeking an easy-care flowering hedge that will certainly turn heads.

Heatwave Salvia Series

Monrovia has added four new varieties to its collection of Heatwave™ Salvia from Australia. Available in an array of bright colors, they have longer bloom cycles and will repeat bloom faster than most Salvias. These varieties have been bred for their compact, rounded habit, reaching a little over 24 inches high and wide. They are disease resistant and have shown a good resistance to rust. A must for the drought tolerant garden. Plant in mass to attract every hummingbird in your neighborhood.

Heatwave™ Blast Sage
Salvia greggi ‘Blast’ P.P.A.F.

USDA Zone 6 – 9
A new range of Salvias, aptly dubbed the ‘Heatwave’ series, were recently introduced ‘down under” to address the dry climate faced by Australian gardeners.
