Outline of Angiosperm Phylogeny
Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese -

Smith, Jr. Professor Emeritus of Botany Department of Biological Sciences Humboldt State Univerity Arcata, California 14 September 2018 The Redwood National and State Parks are located in Del Norte and Humboldt counties in coastal northwestern California. The national park was F E R N S established in 1968. In 1994, a cooperative agreement with the California Department of Parks and Recreation added Del Norte Coast, Prairie Creek, Athyriaceae – Lady Fern Family and Jedediah Smith Redwoods state parks to form a single administrative Athyrium filix-femina var. cyclosporum • northwestern lady fern unit. Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line.

The Green Patch
Northeast Nebraska Master Gardeners The Green Patch Cottage Gardens By Robin Jones , Madison County Master Gardener Old-fashioned plants and flowers have been making a big comeback recently. For someone like me who loves historic homes and Victorian style, this is right up my alley. With a little creativity and planning, you can design a cottage garden of your own. Cottage gardening started in England and was originally meant to oppose the very ornate, formal grandeur of English January 1, 2014 estate gardens. Cottage gardens are informal and densely planted. Their charm is that they look unplanned and rustic. Imagine flowers and vines weaving together as though they sprung up on their own. You will need to choose flowers, greenery, and traditional ma- terials when you plan your design. Flower-lined paths, shrub- bery and borders that go right up to the house, vine-covered fences and arbors all contribute to your look. The most common flowers in a cottage garden are roses. After that, diversity is key to creating the cozy, inviting charm of Volume 6, Issue 1 this style. Lavender, daisies, hollyhocks, foxglove, peonies, phlox, and snapdragons are good choices. You’ll want to choose flowers that grow tall and look a little wild. By selecting two or three hues and working with the various shades along their spectrums, you will have a harmonious color scheme that doesn’t look too deliberate. Purples, pinks, and blues with occasion- al pops of bright yellows and oranges make a good mix. Next you will want to work in your greenery. -
Heart of Uwchlan Pollinator Garden Plant Suggestions – Perennials 2020 Page 1
Pollinator Garden Plant Suggestions - Perennials Heart of Uwchlan Project Tips for Planting a Pollinator Garden • Assess your location. Is it dry? Often wet? Is soil clay or loamy? How much sun or shade? Select plants appropriate to the conditions: “Right plant in the right place.” • Plant so you have blooms in every season. Don’t forget late summer/autumn bloomers; migrating butterflies need that late season pollen and nectar. • Plant for a variety of flower color and shape. That’s prettier for you, but it also appeals to a variety of pollinators. Some bees and butterflies prefer specific plants. • Plant in groups of at least three . easier for pollinators to find and browse. • Don’t forget the birds. Plant tubular flowers for hummingbirds, bushes with berries for birds (see related Plant List for Shrubs). • Finally, do minimal cleanup in the fall. Leave the leaves, dead stems and flower heads. Beneficial insects like miner bees lay eggs in hollow stems, finches will eat the echinacea seeds. Many butterflies and moths overwinter as pupae in dead leaves. Spring Blooming Golden-ragwort (Packera aurea) – mid to late Spring – Damp location, shade Grows freely and naturalizes into large colonies. Yellow flower heads, blooms for over 3 weeks in mide- to late spring. Dense ground cover. Prefers partial sun, medium shade. Prefers moist, swampy conditions. Cut back bloom stalks after flowering. Golden Alexander (Zizia aurea) – blooms May-June – prefers wet habitats but will tolerate dry Attractive bright yellow flower which occurs from May – June, looks like dill in shape. An excellent addition to a wildflower garden because it provides accessible nectar to many beneficial insects with short mouthparts during the spring and early summer when such flowers are relatively uncommon. -
