New hydrangea cultivars for landscape gardens

28.04.2010
Two new compact oakleaf hydrangea cultivars ideal for small gardens have been released by Agricultural Research Service (ARS) scientists.

"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.

Im Focus: Lasers are the key to mastering challenges in lightweight construction

Many joining and cutting processes are possible only with lasers. New technologies make it possible to manufacture metal components with hollow structures that are significantly lighter and yet just as stable as solid components. In addition, lasers can be used to combine various lightweight construction materials and steels with each other. The Fraunhofer Institute for Laser Technology ILT in Aachen is presenting a range of such solutions at the LASER World of Photonics trade fair from June 22 to 25, 2015 in Munich, Germany, (Hall A3, Stand 121).

Lightweight construction materials are popular: aluminum is used in the bodywork of cars, for example, and aircraft fuselages already consist in large part of...

Im Focus: Solid-state photonics goes extreme ultraviolet

Using ultrashort laser pulses, scientists in Max Planck Institute of Quantum Optics have demonstrated the emission of extreme ultraviolet radiation from thin dielectric films and have investigated the underlying mechanisms.

In 1961, only shortly after the invention of the first laser, scientists exposed silicon dioxide crystals (also known as quartz) to an intense ruby laser to...

Im Focus: Advance in regenerative medicine

The only professorship in Germany to date, one master's programme, one laboratory with worldwide unique equipment and the corresponding research results: The University of Würzburg is leading in the field of biofabrication.

Paul Dalton is presently the only professor of biofabrication in Germany. About a year ago, the Australian researcher relocated to the Würzburg department for...

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
