Description: This perennial herbaceous plant is 1½–3½' tall, branching frequently in the upper half to create a bushy appearance. The slender stems are light green, glabrous, and terete (circular in cross-section). Along the entire length of these stems, there are abundant alternate leaves that become gradually smaller in size as they ascend. These leaves are 1½–4" long and 1.5–4 mm. (less than ¼") across; they are linear in shape, entire (toothless) along their margins, medium green, glabrous (hairless), and either sessile or short-petiolate. The leaves have prominent central veins, and some of the wider leaves have pairs of lateral veins that are also visible. The upper stems terminate in clusters of flowerheads that together form a collective inflorescence that is somewhat flat-headed or dome-shaped and irregular. Within this inflorescence, clusters of 3-7 flowerheads often occur that are sessile during the bud stage, although some of them develop short pedicels while they are in bloom. The branches of these floral clusters are similar to the stems, except they are more angular and occasionally short-hairy. Small leafy bracts up to 1" long occur where these branches divide; these bracts are linear in shape. A mature flowerhead is about 3 mm. (1/8") across while in bloom, consisting of 10-12 ray florets and 4-7 disk florets. The petaloid rays of the flowerheads are short-oblong in shape, bright yellow, and ascending to widely spreading. The corollas of the disk florets are cylindrical in shape, 5-lobed, and bright yellow. At the base of each mature flowerhead, small phyllaries (floral bracts) occur in several overlapping series that are appressed together to form an involucre (a cup-shaped structure at the base of the flowerhead). For a mature flowerhead, this involucre is 4-6 mm. long and cylindrical in shape, tapering at its base. Individual phyllaries are elliptic-oblong in shape, light green to pale yellow, glabrous, and oily in appearance. The blooming period occurs from late summer to autumn, lasting about 1-2 months for a colony of plants. In the collective inflorescence of each plant, the flowerheads bloom gradually over a period of time, rather than all at once. Afterwards, the florets are replaced by achenes with small tufts of white hair; they are dispersed by the wind. These achenes are about 1 mm. long, bullet-shaped, and finely pubescent. The root system is fibrous and long-rhizomatous, often forming clonal colonies of plants. [图片]Cultivation: The preference is full sun, moist to dry conditions, and sandy soil, although this plant readily adapts to other kinds of soil containing loam, clay, silt, or gravel. Cool rainy weather or excessive overhead watering can make the lower leaves vulnerable to rust. During an extended drought, some of the lower leaves may wither away, which is normal. Overall, this little-known plant is easy to cultivate in gardens – perhaps too easy, as it is able to spread aggressively by means of its long rhizomes in the average garden situation. Range & Habitat: Plains Grass-leaved Goldenrod occurs occasionally throughout Illinois, but it is more common in the northern and western areas of the state (see Distribution Map). This plant is native to the state. The distribution map is from Jones & Fuller (1955), rather than the ILPIN database, because of some inaccuracies in the latter. Habitats include black soil prairies, sand prairies, gravel prairies, railroad prairies, meadows along rivers, rocky glades, roadsides, areas along railroads, and sandy fields. Plains Grass-leaved Goldenrod is more typical of areas to the west in the Great Plains, but it is still locally common in some parts of the state. [图片]Faunal Associations: The nectar and pollen of the flowerheads attract an abundance of bees, wasps, flies, small butterflies, skippers, moths, beetles, plant bugs, and stink bugs. A plasterer bee, Colletes simulans armata, and such Andrenid bees as Andrena hirticincta, Andrena nubecula, and Andrena simplex, are specialist pollinators (oligoleges) of goldenrods, including Euthamia spp. The Goldenrod Soldier Beetle (Chauliognathus pennsylvanicus), in particular, is a common visitor of the flowerheads. Other insects feed on the foliage and other parts of Plains Grass-leaved Goldenrod. These species include a leaf beetle, Exema byersi, and such grasshoppers as the Western Grass-green Grasshopper (Hesperotettix speciosus), Meadow Purple-striped Grasshopper (Hesperotettix viridis), Keeler's Grasshopper (Melanoplus keeleri luridus), and Scudder's Short-winged Grasshopper (Melanoplus scudderi latus); see Clark et al. (2004) and Campbell et al. (1974). It is not uncommon to find various insects hiding within the dense leafy stems and clustered flowerheads during the day, including moths, caterpillars, and predatory insects; Ambush Bugs (Phymata spp.) are particularly common. The foliage of goldenrods is eaten occasionally by mammalian herbivores, particularly when it is young and more tender. Photographic Location: The photographs were taken of plants growing in the webmaster's garden in Urbana, Illinois. [图片]Comments: Different authorities don't agree on the distribution of Plains Grass-leaved Goldenrod (Euthamia gymnospermoides) within Illinois. For example, Mohenbrock (2002) and the ILPIN database restrict the distribution of this species to the northern and western areas of the state, while Jones & Fuller (1955) and A.G. Jones (1973) state that this species occurs in other areas of the state. In my experience, these latter authorities are correct, as I have encountered Plains Grass-leaved Goldenrod in some railroad prairies of east-central Illinois. It is easy to confuse this species with the more common Grass-leaved Goldenrod (Euthamia graminifolia). Plains Grass-leaved Goldenrod differs by having less than 20 florets per flowerhead (including both disk & ray florets), hairless stems, slightly more narrow leaves, and a more bushy appearance from densely branched stems. Grass-leaved Goldenrod, in contrast, has more than 20 florets per flowerhead, stems with lines of hair, slightly wider leaves, and a less branched appearance. Another species, Lake Grass-leaved Goldenrod (Euthamia remota), differs from Plains Grass-leaved Goldenrod by having slightly more slender leaves and shorter involucres (3-4 mm. long) on its mature flowerheads. Lake Grass-leaved Goldenrod probably should be reclassified as a disjunct population of Coastal Grass-leaved Goldenrod (Euthamia caroliniana); see efloras for more information.

Description: This herbaceous perennial plant is 2-3½' tall. Sometimes it is slender and little branched, while at other times it branches frequently, creating a bushy appearance. The slender stems usually have lines of fine white hairs. The alternate leaves are linear and have smooth margins. The larger leaves have 3 conspicuous veins, although the smaller ones usually have only a single conspicuous vein. They are up to 4" long and 3/8" across, or slightly wider. Sometimes there are a few white hairs near the base of the leaves and along the central vein on the underside. There are clusters of small composite flowers at the apex of the plant and many of the upper side stems. These flower clusters are usually rather flat-headed, but they sometimes assume a round-headed appearance. Each composite flower is yellow, consisting of about 21-35 disk florets and ray florets (when considered together). It is only about 1/8" across – smaller than the composite flowers of other goldenrods. These compound flowers often bloom gradually, rather than simultaneously, with older flowers turning brown while younger flowers are still in the bud stage. The blooming period is late summer to early fall, and lasts about 1 month. Sometimes there is a mild floral scent. The root system is fibrous, and new plants develop vegetatively from rhizomes. Overall, Grass-Leaved Goldenrod is rather variable across different localities. Cultivation: The preference is full sun and moist conditions. However, this plant tolerates drier conditions, and can be surprisingly drought tolerant. The soil should contain high amounts of organic matter; some varieties of this plant also grow in moist sandy soil. Powdery mildew seems to bother this goldenrod less often than many others. It is easy to grow, but can spread aggressively in moist sunny places. [图片]Range & Habitat: Grass-Leaved Goldenrod occurs occasionally in most counties of Illinois (see Distribution Map), where this plant is native. However, it can be locally common in some wetlands areas. Habitats include moist black soil prairies, edges of marshes, sandy pannes between dunes, calcareous seeps, borders of lakes, abandoned fields, and ditches along railroads. Grass-Leaved Goldenrod occasionally occurs in drier habitats, but it has greater trouble competing with other forbs, such as Solidago canadensis (Canada Goldenrod), in such places. Faunal Associations: The small flowers attract many kinds of insects, including long-tongued bees, short-tongued bees, wasps, flies, butterflies, moths, and beetles. Various wasps and a few beetle species, such as Chauliognathus pennsylvanicus (Goldenrod Soldier Beetle) and Epicauta pensylvanica (Black Blister Beetle), seem to be especially attracted to the flowers. The caterpillars of several species of moths eat various parts of this and other goldenrods (see Moth Table). The seeds are eaten by the Eastern Goldfinch and Swamp Sparrow to a limited extent, while the foliage is occasionally consumed in limited amounts by the Greater Prairie Chicken, Cottontail Rabbit, and White-Tailed Deer. [图片]Photographic Location: The photographs were taken at Meadowbrook Park in Urbana, Illinois. Comments: Grass-Leaved Goldenrod has more slender leaves than other goldenrods in Illinois, except for Euthamia gymnospermoides (Plains Grass-Leaved Goldenrod). However, there is only a single conspicuous vein in the largest leaves of this latter species, its stems are hairless, it has only 12-20 disk and ray florets in a compound flower (when considered together), and it is usually more branched and bushy in appearance. Grass-Leaved Goldenrod also differs from the latter species by preferring more soggy habitats.

Dahlia (Dahlia spp.) is not above getting infected with fungus. Specifically, dahlia leaves may become mottled with mold for two reasons: Botrytis cinerea or powdery mildew. Knowing the type of fungus the dahlia is infected with is the first step in curing it. After identifying the type of fungus, use a combination of good care and the right remedy to restore your dahlia to full health. [图片]Identifying the Mold Botrytis cinerea, commonly called gray mold, is aptly named for the woolly, gray mold spores that spread atop masses of brown, water-soaked spots. The dahlia's petals are more likely to be covered by gray mold than leaves, but leaves may be infected if they are injured, dead or growing directly from a food base such as a fallen petal. If the leaves are covered in a dry, white mold, chances are they are infected with powdery mildew, not gray mold. Powdery mildew grows on older leaves and stems, and may cause the leaves to become discolored and die. Unlike gray mold, it does not need moisture to germinate, and it does not cause brown, water-soaked spots. Removing Plant Debris Reducing the amount of decaying plant matter the fungus has access to will help prevent and control gray mold and powdery mildew. Tend to the dahlia plants when they're dry because it helps prevent fungal spores from spreading. Destroy any plant debris -- including faded flowers and dead leaves -- infected with any fungus, and discard them in a paper bag to be thrown out with the trash. For plants infected with gray mold, you may have to clip off entire plants at the base. Clipping off entire plants is not necessary for powdery mildew, but infected leaves should be clipped off. [图片]Reducing Moisture Gray mold spores need free moisture to germinate and infect, and while it is not needed for powdery mildew to survive, it still helps promote its rapid growth. Lowering the amount of moisture may help halt or dramatically slow down the growth of the fungi. To reduce moisture, avoid getting the dahlia plant leaves wet when you water, and water the plant early in the day so it will be dry by the evening. Dahlias only need a deep soaking about once a week, or twice a week if they are not mulched. Fungicides If applied when symptoms first arise, fungicides may help prevent gray mold and powdery mildew from spreading. Chlorothalonil is a fungicide that is effective against gray mold and powdery mildew. Mixing and application instructions vary depending on the brand of chlorothalonil. For example, when using 29.6 percent chlorothalonil, mix 2 teaspoons in 1 gallon of water in a garden sprayer, and coat the dahlia with it in a fine mist every seven to 14 days, until the weather is no longer favorable for the fungus. Wear protective eyewear, gloves, pants and a long-sleeved shirt while handling the fungicide, and be careful not to inhale the mist. Keep children and pets out of the area until the spray has dried.

Tiger Lilies (Lilium columbianum Leichtlin), also known as Columbia lilies, are native to North America. The orange flowers, which may or may not have speckles, grow up to 4 feet tall. They add color and variety to the home garden. The flowers have six petals and blossom during the summer months. The best time to transplant tiger lilies depends on whether you are working with bulbs, bulbils, scales or seedlings. [图片]Propagation You can propagate lilies from bulbs, bulbils, scales or seed. During the growing season, the flower bulb will produce several smaller bulbs that remain attached to it. Even the tiniest bulb in the cluster is fertile if it has roots growing from it. If you want to plant seeds, then do not remove the spent flowers from the plants. This will encourage the plant to produce seedpods. Transplanting Bulbs As tiger lily bulbs never become dormant, according to North Dakota State University Extension, you need to choose the best time to transplant them. The best time is during autumn when the weather is chilly, and after the plants have died back. Dig up the bulbs, separate the cluster and then immediately replant them approximately 1 foot apart. This spacing gives the plants enough distance for healthy growth and flowering. Transplanting Bulbils Bulbils produce bulbs one to two years after you plant them. You will find bulbils on the mature leaves of the tiger lily in late summer or early autumn. They look like plump black beads. Carefully remove them from the leaves and immediately plant them in furrows, recommends the North American Lily Society. [图片]Transplanting Scales As soon as your tiger lilies finish flowering, usually in late summer, dig up the bulbs and remove from four to eight scales from each one. Do not touch the inner layers of scales, as they provide nutrition to the bulb. Additionally, you can remove the same number of scales from newly purchased tiger lily bulbs before planting them. The scales will grow bulblets and form roots. Find detailed directions for transplanting scales in Resources. Transplanting Seedlings Harvest only the brown seedpods, as they contain mature seeds. Depending on your weather, the seedlings should be ready to transplant from 6 to 8 weeks after sowing. Harden off the seedlings for approximately two weeks before transplanting into your garden Plant them in the spring when the soil is warm and all danger of frost is past.

Gladiolus plants send up flowers during the summer. Each flower stem contains several buds that bloom along the length of the stem. The flowers are prized as a colorful garden flower and as a cut flower for indoor display. The plants grow from a tender perennial corm that collects and stores the energy necessary for the following year's growth, making it necessary to properly care for the gladiolus after blooming if you want it to flower again the next year. [图片]Step 1 Cut off the flower stem at its base after all the buds have flowered and completed blooming. Use clean, sharp shears to remove the stems. Step 2 Water the plants weekly after blooming. Provide enough water at each irrigation to keep the top 6 inches of soil moist. Water more frequently if hot weather causes the soil to dry out or the plants to wilt. Step 3 Weed between the gladiolus weekly or as necessary to keep weeds from establishing in the bed. Gladiolus plants can't tolerate weed competition, as the weeds rob the soil of the nutrients and water the corms need to store energy. Step 4 Cut back the foliage to within ½ inch of the ground after the first fall frost causes the foliage to yellow and die back. Dig the corms up after cutting back the foliage. [图片]Step 5 Spread the corms out in a dry, warm location indoors. Dry the corms for three weeks. Step 6 Break the bottom off the corm along the seam and discard the bottom portion, saving only the new top corm. Store the corms in a paper bag in a dry location where temperatures are 35 to 45 degree Fahrenheit until spring planting.
