    HOME & GARDEN INFORMATION http://www.clemson.edu/extension/hgic HGIC 1727 1-888-656-9988 CENTER Pollinator Gardening In 2007, the U.S. Senate designated a week in June as National Pollinator Week to increase the general public’s awareness of the importance of pollinators to food production. What is pollination? Pollination is the movement of pollen from the male flower part (anther) to the female flower part (stigma) on the same plant or between two plants of the same species. Proper pollination is critical for the development of many fruits and crops. These are the parts of a flower. Walker Massey, Clemson University A Monarch butterfly, bumble bee & honey bee on a Sunflower Approximately one third of the food that ends up on (Helianthus annuus). Millie Davenport, ©2015 HGIC, Clemson Extension a plate is there because of pollinators. When pollination is mentioned, most people think of Planting a pollinator garden will encourage the honey bees but there are so many other insects that presence of native pollinators. Like all living things, help get the job done such as native bees, beetles, pollinators need food, shelter, and water. Start by flies, wasps and butterflies. selecting a sunny area in the landscape and evaluating the area for existing nest sites, nectar Of these, bees are a very important group for sources and habitat. Then add plant species to the pollination because they deliberately harvest pollen area that will increase nectar and pollen sources for to feed their offspring; they visit similar flower pollinator insects through the spring, summer and species per foraging trip and accidentally transfer fall months.

Blüte von Tradescantia ohiensis Es sind mehrjährige krautige Pflanzen, einige Arten sind sukkulent. Wie bei Einkeimblättrigen Pflanzen üblich sind die Blüten dreizählig. Die Blüten sind radiär. Die beiden Blütenhüllblattkreise sind deutlich verschiedengestaltig, sie haben also Kelch- und Kronblätter. Die Blütenhüllblätter sind meist frei oder nur an der Basis ein wenig verwachsen. Sie bilden dreikammerige Kapselfrüchte mit ein bis zwei Samen pro Kammer. Bei Pflanzung in Ziergärten sollte man beachten, dass sich einige Arten unkrautartig vermehren und es sehr schwierig ist, diese Gewächse zu kontrollieren.

    Native Plants for Your Backyard

    U.S. Fish & Wildlife Service Native Plants for Your Backyard Native plants of the Southeastern United States are more diverse in number and kind than in most other countries, prized for their beauty worldwide. Our native plants are an integral part of a healthy ecosystem, providing the energy that sustains our forests and wildlife, including important pollinators and migratory birds. By “growing native” you can help support native wildlife. This helps sustain the natural connections that have developed between plants and animals over thousands of years. Consider turning your lawn into a native garden. You’ll help the local environment and often use less water and spend less time and money maintaining your yard if the plants are properly planted. The plants listed are appealing to many species of wildlife and will look attractive in your yard. To maximize your success with these plants, match the right plants with the right site conditions (soil, pH, sun, and moisture). Check out the resources on the back of this factsheet for assistance or contact your local extension office for soil testing and more information about these plants.

Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

    Chapter Four: Landscaping with Native Plants A Gardener’s Guide for Missouri Landscaping with Native Plants A Gardener’s Guide for Missouri Introduction Gardening with native plants is becoming the norm rather than the exception in Missouri. The benefits of native landscaping are fueling a gardening movement that says “no” to pesticides and fertilizers and “yes” to biodiversity and creating more sustainable landscapes. Novice and professional gardeners are turning to native landscaping to reduce mainte- nance and promote plant and wildlife conservation. This manual will show you how to use native plants to cre- ate and maintain diverse and beauti- ful spaces. It describes new ways to garden lightly on the earth. Chapter Four: Landscaping with Native Plants provides tools garden- ers need to create and maintain suc- cessful native plant gardens. The information included here provides practical tips and details to ensure successful low-maintenance land- scapes. The previous three chap- ters include Reconstructing Tallgrass Prairies, Rain Gardening, and Native landscapes in the Whitmire Wildflower Garden, Shaw Nature Reserve.
