  • Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE
    Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus.

As I watched these magnolias bloom each spring, I became more intrigued with their beautiful Bowers and began driv- ing around Green Bay to observe and admire some of the established trees. My admiration for the genus contin- ued to grow each year as I began col- lecting more information about these magnificent plants. One summer I was in the Detroit area and I decided to call this magnolia expert, Phil Savage, that I had read so much about. I can vividly remember calling Phil from a telephone booth on Telegraph Road and finding mysell, an unknown amateur, talking to a magnolia expert who from the first made me feel like a lifelong friend.

  • May 15, 2016 Passing Peony and Iris Plants on from Generation to Generation Annette Meyer Heisdorffer Daviess County Extension Agent for Horticulture
    May 15, 2016 Passing Peony and Iris Plants on from Generation to Generation Annette Meyer Heisdorffer Daviess County Extension Agent for Horticulture After lunch on Mother’s Day, my mom and I surveyed her garden, especially the peonies. We both agreed that I needed to propagate her peonies and plant them in my garden. These are special, because I remember them growing in my grandmother’s garden. Peonies are commonly passed down from generation to generation. My goal is to someday share them with my twins. Our discussion included the irises, which are another heritage plant. Both plants are blooming beautifully in May and are spectacular in the garden. Information about these two plants will be provided in this article. Peony (Paeonia officinalis, Paeonia lactiflora, and hybrids) is a herbaceous perennial, which means at the end of the growing season it will die back to the ground. However, the plant returns year after year. Peonies grow best in full sun and well-drained soil. There are tree peonies (Paeonia suffruticosa) which have a woody stem, but those are not as common and require different growing conditions. The tree peony will not be discussed here. According to Dr. Rick Durham, Extension Specialist for Consumer Horticulture, peonies can be found in landscapes across Kentucky. Peonies have a long life span and are commonly grown in the garden. When planting the root, make sure it is not too deep. The eyes or bud should be just below the surface of the soil. If it is planted too deeply, the plants won't bloom.

  • The Iris- Empress of Flowers
    The Iris- Empress of Flowers by Susan Camp If the rose is the queen of flowers, then the regal iris must be the empress. She stands tall, elegantly nodding her head to lesser flowers and mere mortals. The tall bearded iris, in particular, always attracts attention and admiration from gardeners and passersby. One cannot help but pause and appreciate the delicate construction of the blossom and breathe in the sweet fragrance. The colors of the iris range from white through sherbet shades to deeper hues, all the way to purples so deep they are almost black. The colors seem especially vivid this spring. The iris is named for the Greek messenger goddess, symbolized by the rainbow. While it is fun to romanticize the iris and imagine it as a regal representation of the flower world, the iris is a plant with specific cultural needs and several pests and diseases. Iridaceae is a huge genus of 200-300 species. Most species grow from either rhizomes or bulbs. A few grow from fleshy tubers. The species are immensely diverse. The most popular irises grown in the United States are the tall bearded and other bearded varieties. The tall bearded iris, which is rhizomatous, is the focus of this column, but if you enjoy the beauty of the flower, the possibilities for your garden are almost infinite. The tall bearded iris can reach a height of 2 ½ feet. The leaves are vivid green, fleshy, and sword-shaped. The showy flowers consist of three upright inner petals called standards and three outer hanging petal-like sepals, known as falls.

Lindgren, Horticulture Specialist Iris culture emphasizes the best in site selection and preparation, planting, culture, and insect and dis- ease control. Irises are among the most popular and beautiful garden flowers for Midwest landscapes (Figure 1). More than 200 species of irises have been found in the wild and from these species, thousands of varieties have been named and made available for public use. Iris plants range in height from just a few inches to over 3 feet and are adapted to a variety of environmental conditions. The standard iris, Japanese iris, Siberian iris, Spuria and yellowflag types are suitable for Nebraska. Iris flowers can be from 1 or 2 inches across up to 8 to Figure 1. Irises 10 inches across and come in almost every color and often in two-color combinations. Irises can be selected to have continuous flowering from early April through June by using Planting an assortment of iris species and cultivars. Irises can be divided into “bearded” and “beardless” Irises grow from an enlarged underground stem called types. The term “bearded” refers to the presence of bushy a rhizome. These rhizomes grow just below the soil surface. “beards” on each of three drooping, petal-like sepals, called They are the source of growth for fans of leaves, flowers falls.
