Hummingbird Flowers Hummingbirds Are Attracted to Flower Colors and Nectar, Not Fragrance

Sunrise Birding, LLC, Birding & Wildlife Tours For more information, go to http://www.sunrisebirding.com Hummingbird Flowers Hummingbirds are attracted to flower colors and nectar, not fragrance. Some cultivated hybrids produce less nectar than their wild counterparts, but they still make excellent additions to your hummingbird garden. Highlighted plants are favorites.

Lesson 3 RECOGNISING PLANT FAMILIES and IDENTIFYING PLANTS Aim Distinguish Between Different Plant Families and to Become Profi
Lesson 3 RECOGNISING PLANT FAMILIES AND IDENTIFYING PLANTS Aim Distinguish between different plant families and to become proficient at identifying plants. The best way to build your ability to identify plants is by working with or handling a variety of different plants on a daily basis. The first ten plant names you learn are always much more difficult than the next ninety. Similarly, the first 100 names are always much more difficult than the next 900. If you plan to be a skilled gardener, landscape designer, or horticulturist: you need to learn to identify hundreds of different plants. As you have seen earlier; there is a system in identifying plant names. BECOME FAMILIAR WITH PLANT FAMILIES If you can get to know the way the system works, and the broad categories, the whole thing starts to make a great deal more sense. Each new name you confront is able to be associated with things and remembered more easily. FOR EXAMPLE: “When I see a plant with a daisy flower, I immediately know that it is in the Asteraceae family. Even if the genus is new to me, I will be more likely to remember it because I’m not only thinking: This is the genus of this new plant , but I am also thinking: This new genus is in the Asteraceae family. In essence, my brain is registering two pieces of information instead of one and that doubles the likelihood of me remembering the plant. BECOME FAMILIAR WITH LATIN Plant naming is based on the ancient Roman language of Latin.

Diversity of Carotenoid Composition in Flower Petals
JARQ 45 (2), 163 – 171 (2011) http://www.jircas.affrc.go.jp Diversity of Carotenoid Composition in Flower Petals REVIEW Diversity of Carotenoid Composition in Flower Petals Akemi OHMIYA* National Institute of Floricultural Science, National Agriculture and Food Research Organization (Tsukuba, Ibaraki 305–8519, Japan) Abstract Carotenoids are yellow, orange, and red pigments that are widely distributed in nature. In plants, car- otenoids play important roles in photosynthesis and furnishing flowers and fruits with distinct colors. While most plant leaves show similar carotenoid profiles, containing carotenoids essential for photo- synthesis, the carotenoid composition of flower petals varies from species to species. In this review, I present a list of carotenoid composition in the flower petals of various plants and discuss the possi- ble causes of qualitative diversity.

This genus is consists of four species and indigenous to South America. The plants of this genus are being applied in traditional uses in Brazil. This review of the scientific work about Pyrostegia genus was highlighting and updating their traditional uses, phytochemical compounds, pharmacological activities, genotoxicity tests, and toxicity studies. The information was systematical with the scientific literature database, including Elsevier, Google Scholar, PubMed, Science Direct, and Scopus, and Springer. The literature survey showed various traditional uses of Pyrostegia genus, such as drugs to therapy diarrhea, coughing, vitiligo, jaundice, and respiratory system-related diseases, i.e., colds, coughs, and bronchitis. Phytochemical compounds from the Pyrostegia genus have shown the presence of flavonoids, phenolic compounds, phenylpropanoids, phenylethanoid glycosides, triterpenes, and sterols. The extract of Pyrostegia genus has a variety of pharmacology actions, i.e., antioxidant, antimicrobial, antifungal, anti-inflammatory, wound healing activities, antinociceptive, analgesic, vasorelaxant activities, antitumor, cytotoxic, hepatoprotective, antitussive, anthelmintic, hyperpigmented, treatment of sickness behavior, estrogenic, antihypertensive, and immunomodulatory.

Pyrostegia Venusta1
Fact Sheet FPS-496 October, 1999 Pyrostegia venusta1 Edward F. Gilman2 Introduction Also known as Pyrostegia ignea, Flame Vine grows rapidly climbing by tendrils, this vigorous evergreen vine makes a brilliant fall and winter display of reddish-orange, 3-inch-long tubular flowers borne in clusters of 15 to 20 (Fig. 1). Covering everything which can offer a good support, Flame Vine should be planted with caution as it has been known to cover, then strangle trees with its rampant growth. It has escaped cultivation in much of Central Florida and is often seen in flower during the winter and spring growing in trees. It can be found occasionally in the southern parts of hardiness zone 8b. Heavy or frequent pruning is needed to restrain it to trellises or arbors, but the brilliant flower display makes this extra work worth the effort. It is ideal for covering fences but will often produce most of the flowers and foliage at the top of the fence. Regular heading back several of the stems can help develop some of the flowers and foliage on the lower and middle portions of the fence. General Information Figure 1. Flame Vine.

Environmental Weeds (NR&Mqld)
Extracts from published the paper: ‘Assessment of invasive naturalised plants in south-east Queensland” George N. Batianoff and Don W. Butler, Queensland Herbarium, Environmental Protection Agency, Brisbane Botanic Gardens, Mt Coot-tha Road, Toowong, Queensland, 4066, Australia. Full copy of the Paper can be sourced from the Plant Protection Quarterly Vol 17(1) 2002 Summary A list of 200 invasive naturalised species was prepared as a working document for the compilation of an environmental weed list for southeast Queensland. Species were selected from the 1060 naturalised taxa and were ranked based upon invasiveness and frequency in non-agricultural areas. The list was compiled using records of 1413 vegetation sites, 10163 herbarium specimens and ranking scores of a thirteen member assessment panel. The study area was defined by the Southeast Queensland Environmental Weeds Strategy Working Group and was based on Local Government Areas. It covers in the North from Shires of Monto across to Miriam vale and down to the border. The task of distinguishing weeds of disturbance (ruderal) from weeds of natural areas (environmental) was addressed by categorising species invasiveness and referring to a panel of thirteen weed scientists and field botanists. The expert assessment panel included members of four organisations. Tom Anderson, Trevor Armstrong and Dane Panetta are weed scientists at Alan Fletcher Research Station, Department of Natural Resources and Mining. George Batianoff, Anthony Bean, Paul Forster, Ailsa Holland, Bill McDonald, Sue Phillips and Kathy Stephens are botanists at Queensland Herbarium, Environmental Protection Agency. Michael Olsen and John Swarbrick are environmental consultants representing private enterprise. Paul Grimshaw is a technical officer representing Queensland Parks and Wildlife Service.

Different Methods for Surface Sterilization of Pyrostegia Venusta
Plant Cell Culture & Micropropagation ISSN:1808-9909 Different methods for surface sterilization ofPyrostegia venusta (Ker Gawl.) Miers (Bignoniaceae) leaf explants Diferentes métodos para a esterilização superficial de explantes foliares de Pyrostegia venusta (Ker Gawl.) Miers (Bignoniaceae) Mairon César Coimbra1, Ana Hortência Fonsêca Castro1* ABSTRACT A fast, simple, economical and effective method of sterilization using ethanol and sodium hypochlorite in presented. Eighteen different surface sterilization methods were evaluated using leaf explants ofPyrostegia venusta growing in fragments of the Brazilian Cerrado. All protocols used sought to combine technical routine in order to determine the fastest and cheapest method of asepsis. Our results showed that methods named A13 and A17, which uses two immersion procedures: ethanol 70% for 1 minute + sodium hypochlorite 1% for 5 minutes and ethanol 70% for 1 minute + sodium hypoclorite 3% for 10 minutes, respectively, were the most effectives. The search for a simple, rapid and economical method of sterilizing explants for tissues culture causes us to recommend the A13 protocol for presenting reduced contamination and oxidation values of explants.
