The LSU AgCenter provides annual outlooks for different agriculture commodities in Louisiana. 2008 was a tough year for nursery growers with the national economic slowdown, along with damage to the industry from Hurricane Gustav, Hurricane Ike and snowfall in December. Here is an overview of the current national and state situation.

Landscape evaluation observations were taken on new plants from Ball Seed, Pan American Seed and Ball Flora Plant in 2007. Here is the completed report from LSU AgCenter work at Burden Center and the Hammond Research Station.

Snowfall across the southern and central portions of the state on December 11, 2008, caused considerable damage to Louisiana's nursery industry via damage to greenhouse structures and plant material. Here is a report on the estimate of economic damage.

(Distributed 01/16/09) Three new roses representing three classes of roses are the 2009 All-America Rose Selections winners. The three are Pink Promise, a hybrid tea; Cinco de Mayo, a floribunda; and Carefree Spirit, a landscape shrub.

Landscape evaluation observations were taken on new plants from Ball Seed, Pan American Seed and Ball Flora Plant (now collectively referred to as Ball Horticulture) in 2008. Here is the completed report from LSU AgCenter work at the Hammond Research Station.

The Zahara series of zinnias are new from Ball Horticulture Company for 2009. There are four cultivars and a mix available. This is a Zinnia marylandica species.

The 2009 All-America Rose Selection (AARS) winners are Pink Promise, Cinco de Mayo and Carefree Spirit. A landscape study on these three cultivars was initiated in spring 2008 at the LSU AgCenter’s Burden Center in Baton Rouge, LA. The purpose of this study was to determine the overall landscape performance of these new AARS winners as measured by visual quality ratings and blackspot susceptibility.

(Distributed 12/15/08) Although the exact costs aren’t in yet, the unexpected snowfall on Dec. 11 caused more damage to Louisiana’s commercial ornamental horticulture industry than hurricanes Gustav and Ike. “Wholesale growers in the Forest Hill area and the Florida parishes saw the most damage, and these areas represent the two major nursery production areas in the state,” said Allen Owings, LSU AgCenter horticulture specialist at the Hammond Research Station.

The report includes enterprise production cost budgets for the following container-grown ornamental crops in plant hardiness zones 8 and 9: indica azalea, crape myrtle, liriope, southern live oak, lantana and fig.
