"Plant with Potential" is a new outreach program created at the Hammond Research Station to annually introduce and distribute ornamental plants.
A hosta trial was conducted at the LSU AgCenter Hammond Research Station from 2009 to 2013 with the objective of selecting hostas for southern Louisiana and similar climate. Top 10 varieties were selected based on four years of evaluation. Varieties that do not return from winter dormancy and those exhibiting stresses are noted as well.
A total of 38 caladium varieties were evaluated at the LSU AgCenter Hammond Research Station during the summer of 2009 for their landscape performance, including foliage color, fullness and plant uniformity. The top 10 performers are presented here. (Caladium tubers were donated by Classic Caladiums and Happiness Farms.)
Forty-six ornamental pepper varieties commercially available to growers and gardeners were evaluated during 2007 and 2008 for their garden performance in the Gulf States at three locations: Hammond (La.), Crystal Spring (Miss.) and Verona (Miss.). Variety performance from the Hammond Research Station trials are presented in the attached PDF file. Top ten cultivars were highlighted. Please see related article for their photos.
The LSU AgCenter has a landscape trial of Knock Out rose varieties at Burden Center in Baton Rouge and also at the Hammond Research Station in Hammond. Blackspot ratings for 2008 are included here.
Sweet peas are an excellent cool-season annual for Louisiana. The flowers are popular for cutting and bundling because they come in an array of colors and have an intoxicating scent. Seeds should be sown directly in the garden in October or transplanted from containers in November. Sweet peas are vines so the plants need support (fence, netting, etc.) or a trellis to grow on. Sweet peas start blooming in late March and last up to two months, longer if deadheaded regularly.
A properly designed and operated irrigation system will ensure that the critical factor of soil moisture will be there to sustain healthy plant growth.
Interest in daylilies is still strong despite rust problems over the past several years. New daylily selections and All-American daylily winners need to be evaluated in the Gulf South for landscape performance.
Violas, a close relative to the pansy but with smaller flowers, can provide a mass of color on the darkest winter day. Several viola series perform well in Louisiana, but sometimes it's difficult to choose the viola you want with so many series and colors available. The pictures included on this page are all from the annual bedding plant trials performed at the Burden Center in Baton Rouge.
Studies of water distribution uniformity and fertigation uniformity with sprinkler irrigation were conducted in a commercial container nursery. The first phase of the study consisted of determining water uniformity for two sprinkler heights. The second phase consisted of determining fertilizer application uniformity.
A two-acre camellia garden at the LSU AgCenter’s Hammond Research Station is now open again, thanks to the efforts of the Tangipahoa Parish Master Gardeners.
This bibliography was compiled at a time of increasing concerns about the health status of baldcypress forests in Louisiana and beyond. This bibliography intends to provide researchers, decision makers and forestry professionals with a comprehensive reference in this subject. (PDF Format Only)
The green industry is the production, sale and maintenance of ornamental plants and related products. The purpose of this study was to estimate the impact of the green industry on Louisiana’s economy. (PDF format only)
