"Ruby Slippers" and "Munchkin" are the latest cultivars released by ARS geneticist Sandy Reed with the U.S. National Arboretum's Floral and Nursery Plants Research Unit's worksite in McMinnville, Tenn. The arboretum is operated by ARS, the principal intramural scientific research agency of the U.S. Department of Agriculture (USDA).
The new cultivars are the first compact forms of Hydrangea quercifolia, a species of hydrangea native to the southeastern United States, to be released by ARS. H. quercifolia is commonly known as oakleaf hydrangea because its leaves resemble those from oak trees. According to Reed, currently available oakleaf hydrangea cultivars are taller than desired for small landscape gardens or, if shorter, don't have good flowering qualities.
Ruby Slippers and Munchkin address both of these issues. The new cultivars are small in stature and have large flower heads that stay upright, even after heavy rains. They grow 3-4 feet tall and 4-5 feet wide after nine years of growth, with flower heads held upright above their leaves, making them particularly suited for use in small residential landscapes. Flowers on Ruby Slippers open white but quickly turn pale pink and deepen into rose, while those on Munchkin open white and gradually turn medium pink. Both plants flower in early summer.
Like other oakleaf hydrangeas, Ruby Slippers and Munchkin can be grown in full sun or light shade and are hardy in USDA zones 5 to 8. They can be used in shrub borders or mass-planted in large areas. The plants have been evaluated by cooperators throughout the United States, and cooperators are currently increasing stock. Reed anticipates the plants will be widely available for sale to consumers in the next year or two.
Nursery crops are a multi-billion dollar industry. Wholesalers in 17 states surveyed by the USDA's National Agricultural Statistics Service grossed $4.65 billion in sales in 2006, the last year for which figures are available. That's an increase of 17 percent from 2003 sales. Deciduous shrubs like the oakleaf hydrangea accounted for 14 percent of the industry's total sales in 2006.

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
When an earthquake hits, the faster first responders can get to an impacted area, the more likely infrastructure--and lives--can be saved.
The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.
From April 13 to April 17 at the Hannover Messe (hall 2, exhibit booth C16), engineers from the Fraunhofer Institute for Nondestructive Testing IZFP will be...
