  • Black-Eyed Susan - Rudbeckia Fulgida Var
    Black-eyed Susan - Rudbeckia fulgida var. sullivantii ‘Goldsturm’ A favorite summertime flower, the Black-eyed Susan, with its bright, golden-yellow flowers, produces a ‘gold storm’ of blooms in gardens everywhere. Selected by the Perennial Plant Association as the 1999 Perennial of the Year, this rudbeckia has been acclaimed internationally as one of the most popular perennials for the past fifty years. produces masses of golden color all summer long. It can be one of the most important flowers in the perennial garden. A member of the huge aster or composite family, they typically stay in a basil rosette their first year. Then during the second year produce upright, branching stems with orange-gold flowers. The rough- textured leaves are diamond shaped, and the plant produces erect, bristly stems about thirty-six inches tall. It’s significant compact habit produces long-blooming flowers, and is low maintenance. This spectacular perennial tolerates poor clay soils and mild droughts, but grows best in well- drained and moist soil with regular watering. However, it will not tolerate soggy soils. It is a rhizomatous perennial (spreads by rhizomes, making large clumps) with crowded, branching stems. ‘Goldsturm’ performs as well in the high heat and humidity of Houston, as well as tolerate the arid, cold winters of Amarillo. This Black-eyed Susan is at home in the naturalized, semi-wild garden, used as a border, or even a non-invasive ground cover with full sun to light shade. Plants have minimal blooms the first season unless they undergo cold treatment (vernalization). The long, strong stems make this orange coneflower ideal for cutting.

Black-eyed Susan Habitat and Range: Meadows, fields, roadsides, Rudbeckia hirta L. clearings; most of U.S., southern Canada and into Aster or Daisy Family (Asteraceae) Mexico. Herbal Lore: According to Steven Foster and James Duke (Peterson Field Guides' Field Guide to Medicinal Plants: Eastern and Central North America), American Indians used the root tea to treat colds and expel worms and externally as a wash for swelling, body sores and snakebite. They report that the root juice was used for earaches. They also warn that some people's skin is sensitive to the touch of the plant. Similar Species: Three-lobed (or thin-leaved) coneflower (R. triloba) has a branched growth habit and its lowest leaves are usually three-lobed. (Note: Black-eyed Susan may be branching after it has been mowed.) Orange coneflower (R. fulgida) blooms in the Piedmont and mountains from late summer through fall. It has slightly smaller flower heads than black- eyed Susan. According to Maryland Native Plant Society President Cris Fleming, both species are on the watch list in Maryland and are unlikely to be seen. Blooming Time: June - October. Locations: Abundant in fields, meadows, clearings and roadsides throughout the state.

    Rudbeckia fulgida (Orange Coneflower) Botanical Bytes by Bruner By Gregory Bruner Foliage Height: 18-36” Foliage Width: 18-36” Flower Height: 24-36” Foliage Color: Green Flower Color: Yellow USDA Hardiness: 3-8 Moisture: Average Light: Full Sun – Part Sun Rudbeckia fulgida is native to most of the Eastern United States. Cold hardiness is not an issue with this leafy family member, allowing it to be happy down to zone 3. The small rosette of leaves is evergreen but not showy enough to make much of a display during the winter. This species of Rudbeckia is named for Olof Rudbeck the Elder, a Swedish botanist from the 17th century. If we translate fulgida from Latin, it means shining, gleaming, or glittering. These are wonderful adjectives to describe the glowing show of the flowers, which starts mid summer and lasts through fall. Because the Rudbeckia family has many visually similar members, common names can get a bit confusing. Rudbeckia fulgida is often called Black-eyed Susan like its cousin Rudbeckia hirta, but Orange Coneflower is a better description because its yellow flower petals have a bit more orange in them than hirta’s. This member of the Rudbeckia family is very adaptable, allowing it to tolerate a wide range of soil types. The masses of glowing Rudbeckia seen around town and in yards are usually the cultivar “Goldsturm”. Goldsturm was named perennial of the year in 1999 and since then has proven itself to be a garden mainstay. It thrives in well-drained average garden situations that possess partial to full sun conditions.

  • Clasping Coneflower (Dracopis Amplexicaulis)
    Natural Resources Conservation Service Plant Guide Clasping coneflower Dracopis amplexicaulis (Vahl) Cass Plant Symbol = DRAM Common Names: Clasping-leaf coneflower, coneflower (Diggs et. al, 1999) Scientific Names: (Synonym) Rudbeckia amplexicaulis Vahl. (Diggs et. al, 1999) Description General: Clasping coneflower is a native, warm season, annual forb in the Asteraceae family (Missouri Botanical Garden, 2019). Clasping coneflower grows 12 to 28 inches (30 to 71 cm) tall. It arises from a solitary stem which branches out about half way up the plant (Fig.1). The alternately arranged, oblong, glaucous leaves are 1.75 to 4 inches (4 to 10 cm) long. The leaves, at their base, wrap around the stems (Fig.1). This distinctive leaf characteristic is the origin of the species name derived from two Latin words; amplexus meaning ‘encircling’ and caulis meaning ‘stem’. Clasping coneflower blooms in late spring and early Figure 1. Clasping coneflower in bloom. Photo: East summer. The yellow ray flowers or “petals” are similar in appearance to Texas Plant Materials Center, Nacogdoches, TX black-eyed Susan (Rudbeckia hirta) and droop as the flowers mature. The flowerhead is up to two inches in diameter with a black center cone 0.5 to 1.25 inches (1 to 3 cm) high. (Ajilvsgi, 2003). The seeds are small, approximately 5/64” long (2 mm), elliptical in shape, with a wrinkled appearance (USDA NRCS, 2019) (Fig.2). Distribution: Clasping coneflower is the only member of the Dracopis genus in North America (Diggs et al., 1999). It is found in the southeastern United States from Georgia to Texas and north into Missouri and Kansas (Missouri Botanical Garden, 2019).

  • How to Attract Hummingbirds
    info # 36 _________________________________________________________________________________________________________________________ HOW TO ATTRACT HUMMINGBIRDS Hummingbirds love nectar-rich flowering plants with bright red, orange or red-orange tubular-shaped blossoms, but will visit flowers of any color. Keep in mind that using pesticides eliminates garden insects that hummingbirds rely upon for protein. Plant nectar provides instant energy and insect prey provides protein for muscle growth. As these tiny birds feed on nectar plants they also pollinate the blossoms. Hummingbirds require seven times their body weight in nectar daily, so adding a nectar feeder filled with sugar solution will help lure these energetic little birds into your garden. By planting a succession of nectar flowers, shrubs and trees that will bloom from spring to fall, you can give hummingbirds a continual source of food through the seasons. It is also a good idea to provide convenient places for them to nest and perch, and a water source. Just like other birds, hummers love water, so providing water in a shallow bird bath, and especially through a mister or dripper (available at bird stores) will help to attract hummers and other birds too.

  • Mullins Hankins 2906-1331
    ADDING CUT FLOWERS MAY INCREASE PROFITS Andy Hankins, Extension Specialist-Alternative Agriculture - Virginia State University Reviewed by Chris Mullins, Virginia State University 2018 Vegetable growers who sell produce at farmers' markets, at roadside stands, to restaurants and to local supermarkets may find that they can bring in additional income by adding fresh cut flowers to the inventory of products they sell. A number of benefits can be gained from adding cut flowers to a vegetable marketing operation. Cut flowers add diversity. Customers at roadside stands and at farmers markets like to have many choices. The brilliant colors of a 1/4-acre plot of cut flowers growing beside a roadside stand certainly add visual appeal to potential customers coming down the highway. Restaurant managers need fresh cut flowers for table arrangements. They may be just as interested in buying flowers as they are in buying vegetables. All supermarkets now offer sleeved bunches of fresh cut flowers in glass front coolers in their produce sections. Those store managers need flower growers who can deliver sleeved bunches ready for sale. Many growers who interplant rows of cut flowers among rows of vegetables have noticed a reduction in damage to their vegetable crops by pest insects. The flower crops often harbor populations of beneficial predatory and parasitic insects that control the pest species. Production of cut flowers requires many of the same resources as production of vegetables such as irrigation, transplanting equipment, cultivators, etc. The greatest conflict between these two enterprises occurs in the walk-in cooler. Vegetables like broccoli give off ethylene gas, which can cause severe damage to blooming flowers.
