Groundcover Alternatives to Turf Grass
Revision Date: 31 January 2009 Rebecca Pineo, Botanic Gardens Intern Susan Barton, Extension Specialist University of Delaware Bulletin #131 Sustainable Landscapes Series Groundcover Alternatives to Turf Grass Plants that spread over time to cover the ground are referred to as groundcovers. Usually this term denotes low-growing plants, but groundcovers can also refer to taller, spreading shrubs or trees that grow together to create a dense cover of vegetation. Though turf grass is certainly one of the most popular groundcovers and useful for pathways and play surfaces, it is also one that requires relatively high maintenance. The wide range of low-maintenance, highly attractive, wildlife-benefiting groundcovers beckons to home landscapers searching for an alternative to traditional lawn spaces. (For more information about the disadvantages of turf grass lawns, consult the fact sheet “Turf Grass Madness: Reasons to Reduce the Lawn in Your Landscape,” available at http://www.ag.udel.edu/udbg/sl/vegetation.html ). What are the benefits of replacing some of your turf grass lawn with groundcovers? Reduces maintenance requirements and associated pollution. Groundcovers whose requirements fit the existing conditions of the site will require less fertilizer, pesticides and mowing than traditional turf grass. Less fertilizer and pesticides means less potential for pollution of runoff stormwater, and reducing lawn mower use cuts down on a significant source of air pollution. Offers higher wildlife value than a monoculture of turf grass. Diversity of vegetation supports a diversity of insects, the basis of the food web for local and migrating birds, small mammals, amphibians and reptiles as well as a variety of other beneficial wildlife. -

Petition Number 08-315-01P for a Determination of Non-Regulated Status for Rosa X Hybrida Varieties IFD-52401-4 and IFD-52901-9 – ADDENDUM 1
FLORIGENE PTY LTD 1 PARK DRIVE BUNDOORA VICTORIA 3083 AUSTRALIA TEL +61 3 9243 3800 FAX +61 3 9243 3888 John Cordts USDA Unit 147 4700 River Rd Riverdale MD 20737-1236 USA DATE: 23/12/09 Subject: Petition number 08-315-01p for a determination of non-regulated status for Rosa X hybrida varieties IFD-52401-4 and IFD-52901-9 – ADDENDUM 1. Dear John, As requested Florigene is submitting “Addendum 1: pests and disease for roses” to add to petition 08-315-01p. This addendum outlines some of the common pest and diseases found in roses. It also includes information from our growers in California and Colombia stating that the two transgenic lines included in the petition are normal with regard to susceptibility and control. This addendum contains no CBI information. Kind Regards, Katherine Terdich Regulatory Affairs ADDENDUM 1: PEST AND DISEASE ISSUES FOR ROSES Roses like all plants can be affected by a variety of pests and diseases. Commercial production of plants free of pests and disease requires frequent observations and strategic planning. Prevention is essential for good disease control. Since the 1980’s all commercial growers use integrated pest management (IPM) systems to control pests and diseases. IPM forecasts conditions which are favourable for disease epidemics and utilises sprays only when necessary. The most widely distributed fungal disease of roses is Powdery Mildew. Powdery Mildew is caused by the fungus Podosphaera pannosa. It usually begins to develop on young stem tissues, especially at the base of the thorns. The fungus can also attack leaves and flowers leading to poor growth and flowers of poor quality. -
Germplasm Collection, Characterization, and Enhancement of Eastern Phlox Species
GERMPLASM COLLECTION, CHARACTERIZATION, AND ENHANCEMENT OF EASTERN PHLOX SPECIES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Graduate School of The Ohio State University By Peter Jeffrey Zale, M.S. Graduate Program in Horticulture and Crop Science The Ohio State University 2014 Dissertation Committee: Dr. Pablo Jourdan, Advisor Dr. Mark Bennett Dr. David Francis Dr. John Freudenstein Copyrighted by Peter J. Zale 2014 ABSTRACT Plants from the genus Phlox have become a staple of gardens worldwide since their introduction to cultivation about 200 years ago, and are admired as versatile garden and landscape plants, container plants, and cut flowers. Their long-lasting, intensive floral displays in a variety of colors, forms, and seasons rank them among the most widely recognized hardy perennials and annuals. The floral beauty has resulted in extensive breeding and selection in three primary species: the annual Phlox drummondii, and the hardy perennials P. paniculata, and P. subulata. Among these three, hundreds of cultivars have been selected over the last 200 years, but the genus includes other species that may have ornamental potential. Phlox L. (Polemoniaceae) consists of ca. 65 species primarily endemic to North America; 20-23 species occur in the eastern U.S.A. and 40-45 in the west. The western taxa occur primarily in arid, mountainous habitats whereas the eastern taxa occur in a different range of diverse ecosystems and habitats. The eastern species are a polymorphic group arranged into 6 subsections within the genus; this group includes the three main cultivated species and also up to 20 related species that exhibit ornamental characteristics, yet are rarely cultivated. -
Developing Resistance to Powdery Mildew (Podosphaera Pannosa (Wallr.: Fr.) De Bary): a Challenge for Rose Breeders
® Floriculture and Ornamental Biotechnology ©2009 Global Science Books Developing Resistance to Powdery Mildew (Podosphaera pannosa (Wallr.: Fr.) de Bary): A Challenge for Rose Breeders Leen Leus* • Johan Van Huylenbroeck Institute for Agricultural and Fisheries Research (ILVO) – Plant Sciences Unit – Applied Genetics and Breeding, Caritasstraat 21, 9090 Melle, Belgium Corresponding author : * [email protected] ABSTRACT Powdery mildew is the major fungal pathogen of roses in greenhouses and also an important disease on field-grown roses. In the past decade different tools have been developed allowing breeders to develop resistant roses in a more efficient way. Different pathotypes of the fungus, important for resistance testing, were detected. Resistance mechanisms in rose leaves were found and characterized. Screening techniques to evaluate powdery mildew resistance are available. These methods allow pathotype specific inoculation on detached leaves or can be used for the selection of resistant genotypes within a population of thousands of seedlings. New information on the genetic background of powdery mildew resistance became available. Genetic maps providing information on resistance markers are currently being developed and integrated. Marker-assisted selection is expected to be ready soon for use in rose breeding programs for powdery mildew resistance among other traits. This review aims to provide an overview on fundamental information and methodology available and necessary to make progress in breeding for powdery mildew -
Recommended Native Pollinator-Friendly Plant List (Updated April 2021)
RECOMMENDED NATIVE POLLINATOR-FRIENDLY PLANT LIST (UPDATED APRIL 2021) Asheville GreenWorks is excited to share this updated native pollinator-friendly plant list for Asheville’s Bee City USA program! As the launchpad of the national Bee City USA program in 2012, we are gratified that throughout our community, individuals, organizations, and businesses are doing their part to reverse staggering global pollinator declines. Please check out our Pollinator Habitat Certification program at https://www.ashevillegreenworks.org/pollinator-garden-certification.html and our annual Pollination Celebration! during National Pollinator Week in June at https://www.ashevillegreenworks.org/pollination-celebration.html. WHY LANDSCAPE WITH POLLINATORS IN MIND? Asheville GreenWorks’ Bee City USA program encourages everyone to incorporate as many native plants into their landscapes and avoid insect-killing pesticides as much as possible. Here’s why. Over the millennia, hundreds of thousands of plant and animal pollinator species have perfected their pollination dances. Pollinating animals rely upon the carbohydrate-rich nectar and/or the protein-rich pollen supplied by flowers, and plants rely on pollinators to carry their pollen to other flowers to produce seeds and sustain their species. Nearly 90% of the world’s flowering plant species depend on pollinators to help them reproduce! Plants and pollinators form the foundation for our planet’s rich biodiversity generally. For example, 96% of terrestrial birds feed their young exclusively moth and butterfly caterpillars. ABOUT THIS NATIVE PLANT LIST An elite task force, listed at the end of this document, verified which plants were native to Western North Carolina and agreed this list should focus on plants’ value to pollinators as food--including nectar, pollen, and larval host plants for moth and butterfly caterpillars, as well as nesting habitat for bumble and other bees. -

BIOCHEMICAL and COLORIMETRIC STUDY of FLOWER COLOR in PHLOX SPECIES THESIS Presented in Partial Fulfillment of the Requirements
BIOCHEMICAL AND COLORIMETRIC STUDY OF FLOWER COLOR IN PHLOX SPECIES THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Andres Bohorquez-Restrepo, B.S Graduate Program in Horticulture and Crop Science The Ohio State University 2015 Thesis Committee: Dr. Pablo Jourdan, Co-Advisor Dr. Joseph Scheerens, Co-Advisor Dr. Michelle Jones Copyrighted by Andres Bohorquez-Restrepo 2015 ABSTRACT Flower color is arguably the most important phenotypic feature of ornamental plants and extensive selection and breeding is done to develop new colors. Variation in flower color can be caused by different factors such as the composition and concentration of pigments, vacuolar pH and the presence of cofactors. The same color in two flowers may be the result of different mechanisms. Yet quantifying color variation can be challenging. Digital imaging coupled with analytic software is a powerful tool that can transform qualitative measurements of phenotypic characters like color and shape into quantitative data. Such a tool permits both a more objective analysis of traits that can be difficult to measure, as well as integration with molecular and biochemical data. In this study, a germplasm collection of Phlox was examined both for flower color variation as well as for anthocyanidin pigment composition. Phlox is a genus native to North America that includes an array of colorful flowers often described as purple, lilac, pink, red, orange and blue. The principal pigments of Phlox flowers are anthocyanins, but little is known about pigment variation in this genus. Tomato Analyzer (TAn) software was used to examine the variation in color from digital images of flowers of 89 Phlox accessions from the Ornamental Plant Germplasm Center.
