Texas Trillium Arlington, Texas Ecological Services Field Office
U.S. FishU.S &. FishWildlife & Wildlife Service Service Texas Trillium Arlington, Texas Ecological Services Field Office Texas Trillium Trillium texanum Description Texas trillium belongs to the Liliaceae (lily) family and are rhizomatous herbs with unbranched stems. Trillium plants produce no true leaves or stems aboveground. Texas trillium has solitary white to pale pink flowers on a short stalk, situated above three bracteal leaves. It is the only trillium species in Texas with numerous stomata (specialized cells which open and close to regulate gas and water movement into/out of the plant) on Trillium pusillum var. texanum - (Photo Credit- Jason Singhurst) upper and lower surfaces of its bracts. Longevity is unknown, but one study fern (Woodwardia areolata), and showed that white trillium (Trillium green rein orchid (Platanthera grandiflorum) lives at least 30 years clavellata). based on estimates calculated from the number of constrictions on rhizomes. Conservation Although not listed as endangered or Habitat threatened by the State of Texas, Texas trillium habitat is characterized Texas trillium is ranked as a G2 by a shaded, forest understory. It (imperiled) by NatureServe and is flowers before full leaf-out of over ranked as a Sensitive Species by the story species and before being United States Forest Service. The Distribution overtopped by other herbaceous species is also listed on Texas Parks Texas trillium occurs across thirteen species. Texas trillium is found in the and Wildlife Department’s 2010 List counties in East Texas and into ecotone between riparian baygall and of the Rare Plants of Texas and as a northwestern Louisiana (Caddo sandy pine or oak uplands in the Species of Greatest Conservation Parish). -
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. -
Woodland/Shade Gardening by Jimi Blake
V OLUME 24, I SSUE 4 O CTOBER— DECEMBER 2015 Piedmont Chapter North American Rock Garden Society The Trillium Chapel Hill, Durham, Raleigh, NC Woodland/Shade Gardening By Jimi Blake Woodland plants are the brave plants that burst into flower in the spring lifting my spirit and encouraging me to start back to gardening in Hunting Brook, Co. Wicklow, Ireland. These plants are so important in the garden to extend the season of interest and brighten up a shady area. An expanse of deciduous woodland is not necessary to create a woodland garden, though it is a dream situation for this purpose but that shaded area in the corner of the garden where you dump the grass mowings can take on a whole new life, or by simply pruning a shrub to let more light under it will allow for your mini woodland garden. The other type of shade in lots of gardens is the shade creat- ed by walls, which is also suitable for growing woodland plants. In the wild, these plants flower under the dappled shade of the deciduous trees before the leaves shade out the woodland floor during the summer months. Generally the woodland plants finish flowering by early to mid sum- mer and form a ground cover of various shades of green. These plants are called spring ephemerals. Remember the secret of a good woodland garden is the preparation of the soil, as these areas can be quite dry in the summer with the roots of the trees or shrubs taking up the moisture. When I started the woodland gardens in Hunting Brook I cleared the weeds by hand and then dug over the soil and incorporated a mixture of leaf mould or garden compost, and very well rotted farmyard manure creating a delicious mixture for these woodland gems to grow well in. -

Large-Flowered Trilliums Coming up in Spring in Our Childhoo
Large-flowered Trillium or Common Trillium (Trillium grandiflorum) Large-flowered Trilliums Coming Up in Spring In our childhood the woods in late May were full of hundreds of large, waxy white flowers that covered the forest floor. Grandma in her German diary called these trilliums “wild lilies” and also commented that on May14th and 22nd in 1927 and again on May 22nd in 1940 these flowers were numerous and in full bloom. (Freckman, 1994) gave the earliest blooming dates as April 24th. Large-flowered Trillium Bud Opening Today, with more houses and lawns in the country, and fewer undisturbed woodlots those visions of white are less frequently seen. In addition, the White-tailed Deer population has steadily increased and their appetite for tasty trilliums has served to eliminate many stands of this beautiful plant. This is especially troublesome because once the leaves and flowers are plucked, the plant is likely to die. It can no longer produce food to send down to the roots so that it can come back another year. It still grows quite abundantly on the sloping bank along Billings Avenue in the Town of Medford, Wisconsin. Some sources say that deer do not like to graze on steep banks or inclines so that may be why those plants have escaped. We have a patch of trilliums that has grown larger each year in our lawn. Recently we have had to protect these trilliums from the deer that could wipe out the entire patch in a single night. Sometimes seeds from those plants, possibly transported by ants, have grown into new plants in the front lawn. -
Trillium, As an Indicator of Deer Density Hanover Biodiversity Committee October, 2017
[DRAFT v. 10] Trillium, as an indicator of deer density Hanover Biodiversity Committee October, 2017 Rationale for this Report Members of the lily family, such as Trillium and Clintonia, are among the favored foods of deer; 30 species of Trillium are found East of the Mississippi. The decline of these plants is mentioned in multiple publications1 as one key indicator of deer over-abundance. Red Trillium (Trillium erectum), also called ‘wake Robin’, found in the north-east and is (or was) fairly common in many Hanover forested neighborhoods. We suggest that monitoring this plant where it is (or once was) common demonstrates that deer density remains unsustainably high and future monitoring of the plant can help determine both the neighborhood density of deer and also serve as an indicator of change in deer density. Monitoring for this plant is easy, with just a small bit of training about the process. This report suggests a serious decline in biodiversity in Hanover over the past 15 years, as indicated by impact on red Trillium at three sites. We believe that with a focused increase in hunting pressure, this and other declining native plants might recover. Red Trillium is a frequent member of typical ‘rich mesic forests2’ plant communities found in Hanover; other plants often found nearby are Virginia waterleaf, blood root, wild ginger, foam flower, blue cohosh, and certain other members of the lily family. Besides aggressive deer browse, these communities are also threatened in varying degrees by invasive plants: garlic mustard, Dame’s rocket, wild parsnip, wild chervil and forget-me-not as well as the usual woody invaders. -

It can tolerate partial include commonly associated shade but also needs sunlight. 5 species It and other indicator species tend to be strongly limited to partial canopy conditions. In more heavily-wooded sites, these species are usually in a state of decline due to the increasing canopy closure above. They are therefore dependent on canopy gaps, edges, roadsides etc. in densely-wooded areas. 9 In Missouri it cam be found on the crevices and ledges of north-facing dolomite bluffs. -

Executive Summary This survey was a continuation of several years of rare plant survey on San Juan Public Lands. Funding for the project was provided by San Juan National Forest and the San Juan Resource Area of the Bureau of Land Management. Previous rare plant surveys on San Juan Public Lands by CNHP were conducted in conjunction with county wide surveys of La Plata, Archuleta, San Juan and San Miguel counties, with partial funding from Great Outdoors Colorado (GOCO); and in 2004, public lands only in Dolores and Montezuma counties, funded entirely by the San Juan Public Lands. Funding for 2005 was again provided by San Juan Public Lands. The primary emphases for field work in 2005 were: 1. revisit and update information on rare plant occurrences of agency sensitive species in the Colorado Natural Heritage Program (CNHP) database that were last observed prior to 2000, in order to have the most current information available for informing the revision of the Resource Management Plan for the San Juan Public Lands (BLM and San Juan National Forest); 2.
