  • SALT TOLERANT PLANTS Recommended for Pender County Landscapes
    North Carolina Cooperative Extension NC STATE UNIVERSITY SALT TOLERANT PLANTS Recommended for Pender County Landscapes Pender County Cooperative Extension Urban Horticulture Leaflet 14 Coastal Challenges Plants growing at the beach are subjected to environmental conditions much different than those planted further inland. Factors such as blowing sand, poor soils, high temperatures, and excessive drainage all influence how well plants perform in coastal landscapes, though the most significant effect on growth is salt spray. Most plants will not tolerate salt accumulating on their foliage, making plant selection for beachfront land- scapes particularly challenging. Salt Spray Salt spray is created when waves break on the beach, throwing tiny droplets of salty water into the air. On-shore breezes blow this salt laden air landward where it comes in contact with plant foliage. The amount of salt spray plants receive varies depending on their proximity to the beachfront, creating different vegetation zones as one gets further away from the beachfront. The most salt-tolerant species surviving in the frontal dune area. As distance away from the ocean increases, the level of salt spray decreases, allowing plants with less salt tolerance to survive. Natural Protection The impact of salt spray on plants can be lessened by physically blocking salt laden winds. This occurs naturally in the maritime forest, where beachfront plants protect landward species by creating a layer of foliage that blocks salt spray. It is easy to see this effect on the ocean side of maritime forest plants, which are “sheared” by salt spray, causing them to grow at a slant away from the oceanfront.

  • Flower Power
    FLOWER POWER IDAHO BOTANICAL GARDEN WHAT IS A FLOWER? INSTRUCTIONAL OBJECTIVE: When students finish this project, they will have gained respect for the beauty of flowers and appreciate their ecological and practical importance. INTRODUCTION Dear Teacher, The Idaho Botanical Garden is an outdoor learning environment. We want to make your visit comfortable and enjoyable, and ask that your students are dressed appropriately for the weather and have water, especially in the warm weather months. TERMS Angiosperms: Flowering plants that produce seeds enclosed in a fruit. Anthers: The boxlike structures at the top of stamens, where pollen is produced. Botanical garden: A place where plants are collected and displayed for scientific, educational and artistic purposes. Fertilization: The union of male sperm cells and female egg cells. Filament: The stalk of the stamen. Flower: The reproductive structure of an angiosperm. Fruit: A ripened ovary conaining seeds. Nectar: The sweet liquid produced by flowers to attract pollinators. Ovary: The hollow compartment at the base of the pistil which contains ovules. It develops into a fruit containing seeds. Ovules: The structures in a flower ovary that can develop into seeds. Pistil: The female part of a flower; stigma, style, and ovary. Pollen: A yellow, powder-like material containing sperm cells. Pollen tubes: Tubes that carry sperm cells from the stigma into the ovary. Pollination: The process of pollen coming together with the stigma of a flower. Pollinators: Animals which carry pollen from one flower to another. Seed: A structure containing a baby plant and its food supply, which is surrounded by a protective seed coat.

AREA ­ Non-native trees are some of the most beloved plants in the landscape due to their beauty. In addition, these trees are grown for the shade, screening, structure, and landscape benefits they provide. Deciduous trees, whose leaves die and fall off in the autumn, are valuable additions to landscapes because of their changing interest throughout the year. Evergreen trees are valued for their year-round beauty and shelter for wildlife. Evergreens are often grouped into two categories, broadleaf evergreens and conifers. Broadleaf evergreens have broad, flat leaves. They also may have showy flowers, such as Camellia oleifera (a large shrub), or colorful fruits, such as Nellie R. Stevens holly. Coniferous evergreens either have needle-like foliage, such as the lacebark pine, or scale-like foliage, such as the green giant arborvitae. Conifers do not have true flowers or fruits but bear cones. Though most conifers are evergreen, exceptions exist. Dawn redwood, for example, loses its needles each fall. The following are useful definitions: Cultivar (cv.) - a cultivated variety designated by single quotes, such as ‘Autumn Gold’. A variety (var.) or subspecies (subsp.), in contrast, is found in nature and is a subdivision of a species (a variety of Cedar of Lebanon is listed). Full Shade - the amount of light under a dense deciduous tree canopy or beneath evergreens. Full Sun - at least 6 hours of sun daily.

  • Native Or Suitable Plants City of Mccall
    Native or Suitable Plants City of McCall The following list of plants is presented to assist the developer, business owner, or homeowner in selecting plants for landscaping. The list is by no means complete, but is a recommended selection of plants which are either native or have been successfully introduced to our area. Successful landscaping, however, requires much more than just the selection of plants. Unless you have some experience, it is suggested than you employ the services of a trained or otherwise experienced landscaper, arborist, or forester. For best results it is recommended that careful consideration be made in purchasing the plants from the local nurseries (i.e. Cascade, McCall, and New Meadows). Plants brought in from the Treasure Valley may not survive our local weather conditions, microsites, and higher elevations. Timing can also be a serious consideration as the plants may have already broken dormancy and can be damaged by our late frosts. Appendix B SELECTED IDAHO NATIVE PLANTS SUITABLE FOR VALLEY COUNTY GROWING CONDITIONS Trees & Shrubs Acer circinatum (Vine Maple). Shrub or small tree 15-20' tall, Pacific Northwest native. Bright scarlet-orange fall foliage. Excellent ornamental. Alnus incana (Mountain Alder). A large shrub, useful for mid to high elevation riparian plantings. Good plant for stream bank shelter and stabilization. Nitrogen fixing root system. Alnus sinuata (Sitka Alder). A shrub, 6-1 5' tall. Grows well on moist slopes or stream banks. Excellent shrub for erosion control and riparian restoration. Nitrogen fixing root system. Amelanchier alnifolia (Serviceberry). One of the earlier shrubs to blossom out in the spring.
