We had a number of great selections in the trials this year. The top performers in the trials are entered in the ASCFG Cut Flower of the Year contest.

Bromeliads: long-lasting tropical color   Greenhouse Product News February 2003   Rick Schoellhorn
The boom in orchids as flowering potted plants (now listed as the number-two flowering potted plant, just behind poinsettias) and the growing diversity of bromeliad hybrids on the market make it much easier to find reliable sources for some really exotic color. I will look more at orchids sometime in the near future, but for this month I wanted to talk about bromeliads and some of the spectacular, long-lasting hybrids coming on the market.
Dianthus 'Bouquet Purple'   Greenhouse Product News January 2003   Paul Pilon
Dianthus 'Bouquet Purple' has been produced as a bedding plant or cut flower for a few years, and it is still underutilized as a perennial crop. Bouquet Purple has many desirable perennial characteristics such as: quick finishing time from plugs, easy flowering that can be scheduled, hardiness in USDA Zones 4-10 and few known cultural problems. Bouquet Purple is a seed-propagated, interspecific F1 hybrid that produces lavender flowers on strong, well-branched stems. Throughout the country, it has been a terrific performer and has been named winner of the 2000 Minnesota Select Perennial award and the 2001 Mississippi Medallion award.

Producing Ravishing Ranunculus   Greenhouse Product News January 2003   Meriam Karlsson
In the 1960s and 1970s, efforts were intensified to develop seed-propagated ranunculus.

Anthuriums Reinvented   Greenhouse Product News December 2002   Rick Schoellhorn
Anthuriums are one of the crops where a lot of changes have taken place in the last 10 years. Breeding has really changed the face of this crop, but also, there are a lot of misconceptions floating around out there that have limited the adoption and use of this wonderful flower. Anthuriums remain one of the crops that most Northern nurseries bring in as pre-finished or finished, but the sparsely flowered forms of years ago are long since replaced by earlier and heavier-flowering varieties.

Employing Communication in Employment   Greenhouse Product News November 2002   Brandi D. McNally
Two years ago, Tagawa Greenhouses in Brighton, Colo. saw that their production efficiency and product uniformity could be improved through some changes in employee training. By developing a system that integrated training, research and development, and implementation management, they've seen increasing productivity since the beginning of the program. Hiring professional teachers, developing standardized procedures and spending time with individual employees to gain an understanding of their communication levels are just a few of the things they've done to make their training program successful.

University of Florida Field Trials   Greenhouse Product News October 2002   Rick Schoellhorn
The spring field trials at the University of Florida this year contained 180 cultivars of vegetative annuals, both those more common to southern production and also several focus areas. The goal of these trials is to promote plants that are tolerant of extreme high heat and humidity, conditions common across the southeast sunbelt from Florida to West Texas. Obviously, the season here begins very early in the year and, for some plants, ends a lot earlier as well. The results of these trials can be used to help growers refine their late-season selections where heat and humidity have the biggest impact on crop quality.

Heuchera 'Fireworks' Coral Bells   Greenhouse Product News September 2002   Paul Pilon
The Native American perennial heuchera has become one of the hottest, most must-have perennial plants for today's gardens. Fireworks is best recognized by its "explosive" display of light, coral-bell-shaped flowers on wiry stems held over the lightly ruffled bronze foliage. It is a prolific and a long-lasting bloomer that continues flowering from May-August and attracts both butterflies and hummingbirds. It has good re-blooming characteristics and can be used as a cut flower.

Diseases of Perennials   Greenhouse Product News August 2002   Steve Nameth
Disease control of perennials is very similar to that of herbaceous annuals. Number one is knowing what diseases are important and how to identify them. Before you plant anything, be sure that the material you are planting (seed, corm, rhizome, cutting, etc.) is free from diseases and insect pests. Purchasing propagation material from a reputable producer will help ensure high-quality starting material.
Taming the Wild Calibrachoa   Greenhouse Product News July 2002   Erika Berghauer, Jim Barrett and Rick Schoellhorn
As with many vegetatively propagated items, producing Calibrachoa hanging baskets does not come without challenges. Taming vigorous growth to produce a more attractive basket, facilitate shipping and keep plants untangled in a high-density growing situation are concerns. At the University of Florida, we have evaluated the use of growth regulator drench applications to slow the growth of Calibrachoa, which should make this high-value crop more appealing to growers.

Forget-me-not as a Potted Plant   Greenhouse Product News May 2002   Meriam Karlsson
Initial studies on the opportunity to produce forget-me-not as a flowering potted plant are promising. For best plant development and flowering, day length, temperature and light condition following the cold treatment still need to be evaluated. Consumer acceptance of locally produced flowering potted forget-me-not has been overwhelming. The demand for special occasions and the scarce availability suggest consumers are willing to pay a premium price for flowering potted forget-me-not.

Advanced Height Control of Perennials   Greenhouse Product News April 2002   Paul Pilon
Unlike most greenhouse crops, perennials consist of a diverse array of plant species (literally thousands of them). Until recently, relatively little research has been conducted with perennials; therefore, the availability of high-quality cultural information is almost nonexistent. Consumer popularity, increased competition and stricter quality specifications have helped make controlling the height of perennials a real challenge for today’s growers.
