Bachelor's Button, Cornflower - Garden Basics - Flower – Annual (Centaurea cyanus) These cheerful, ragged blossoms are at home in temperate gardens around the world. They bloom so prolifically with so little care that they often are the first plants that children grow on their own. The nickname "cornflower" comes from the fact that the plant grows wild in the grain fields of southern Europe. When Napoleon forced Queen Louise of Prussia from Berlin, she hid her children in a cornfield and kept them entertained and quiet by weaving wreaths of cornflowers. One of her children, Wilheim, later became the emperor of Germany. Remembering his mother's bravery, he made the cornflower a national emblem of unity. Depending upon the variety, plants will grow to between 1 and 3 feet tall and are most effective when massed in beds and borders for color. Bachelor buttons are a cutting garden favorite, and they are one of the easiest flowers to dry for everlasting arrangements. Sowing Bachelor Button Seeds Bachelor buttons are easy to grow from seeds outdoors. Sow in spring, 1 to 2 weeks before the last expected frost, for early summer blooms. They can also be sown in fall in mild climates for early spring blooms. Sow seeds 1/4 inch deep and 1 inch apart. The seeds need complete darkness to germinate, so make sure they are well covered. When seedlings are 1 to 2 inches tall, thin them to 6 to 8 inches apart. The first blooms appear 10 to 12 weeks after planting, and last for about a month. Successive plantings can extend the bloom period. Will they come back next year? Bachelor buttons are annuals, which means they complete their entire life cycle in a single year, and then die. But don't despair; they may be back next year! Bachelor buttons ensure their own survival by dropping seeds that will germinate and grow the following year in most climates. As with most annuals, keeping the spent flowers picked off will encourage the production of more flowers, but to allow them a chance to reseed, leave some of the last flowers to die naturally on the plant. This will give them a chance to drop seeds. Recommended Varieties: Black Magic These 'black' bachelor buttons are actually dark maroon. They combine well with 'Blue Boy' or tall cosmos. Blue Boy These dazzling sky-blue flowers grow about 2 feet tall. Sweet Sultan Imperialis This fragrant variety has 2" flower heads that are perfect for cutting. The blooms have an interesting 'thistle' look. Dwarf Blend This pastel blend is perfect when you need a shorter summer bloomer. o Type annual o Propagation seeds o Light full sun o Flower Color various o Bloom Time early summer to early autumn o Height 24-36 inches o Width 6-12 inches o Soil Requirements alkaline pH, moisture=average or dry o Zones all o Uses cutting bed .

Wildflower Growing Guide Rewilding Project
Wildflower Growing Guide Rewilding Project The flowers that are included in the Pharmabees seed mix are below: Common Knapweed Corn Marigold Oxeye Daisy White Campion Dandelion Corn Poppy Corn Chamomile Cornflower White Clover Bluebell These flowers were chosen by the Pharmabees team. These flowers have been identified as part of a University research project to develop a wild flower seed mix which can be used to support pollinators and to promote biodiversity. These flowers have been identified through our research on honey. Honey with high antibacterial activity was analysed. The pollens found in the honey were identified through DNA analysis. We were able to identify the flowers in your seed mix. We are conducting additional research on these plants and need your help. Please monitor your growing area and watch your flowers grow. We will be asking you to monitor your growing area for pollinators, and to collect some additional data for us. Thank you for being an important part of our research! Instructions: Choose a growing area around 1 meter squared. Firstly, remove all weeds, grass, and other plants. It is very important to remove weeds such as nettles, thistles, and Japanese knotweed. These weeds and grasses grow quickly, and will overtake your wildflower seeds if not removed. Cultivate the growing site to a depth of around 10cm. This can be done with a rake, or on large areas a plough. Sowing can take place throughout most of the year. The months of March/April/August and September are generally most suited. Mix the seeds before spreading. Ensure all the seed is mixed to ensure an even spread.

Plant Polyphenols As Antioxidants Influencing the Human Health
9 Plant Polyphenols as Antioxidants Influencing the Human Health Sanda Vladimir-Knežević, Biljana Blažeković, Maja Bival Štefan and Marija Babac University of Zagreb, Faculty of Pharmacy and Biochemistry, Croatia 1. Introduction Widely distributed in plant kingdom and abundant in our diet plant polyphenols are today among the most talked about concerning the classes of phytochemicals. There are several thousand plant-derived compounds of biogical interest that have more than one phenolic hydroxyl group attached to one or more benzene rings, thus qualifying as polyphenols. In recent years, polyphenols have gained a lot of importance because of their potential use as prophylactic and therapeutic agents in many diseases, and much work has been presented by the scientific community which focuses on their antioxidant effects. Traditionally, herbal medicines with antioxidant properties have been used for various purposes and epidemiological data also point at widespread acceptance and use of these agents. Plant polyphenols have been studied with intention to find compounds protecting against a number of diseases related to oxidative stress and free radical-induced damage, such as cardiovascular and neurodegenerative diseases, cancer, diabetes, autoimmune disorders and some inflammatory diseases. In order to evaluate the efficacy of polyphenols as antioxidants as well as to elucidate the mode of their action, researchers today are using a wide range of experimental models, from the simplest chemical antioxidant assays through the biologically more relevant cellular-based assays to the most accurate animal models, and ultimately clinical studies in humans. The latest scientific knowledge offers a more detailed understanding of the biological effects of polyphenols and their role in human health promotion and disease prevention.

In Northeast India by Centaurea Cyanus L
ISSN. 0972 - 8406 The NEHU Journal, Vol. XVIII, No.1, January-June 2020, pp. 100-111 First record of new ‘invasion’ in northeast India by Centaurea cyanus L. (Asteraceae) Uma Shankar Department of Botany, North-Eastern Hill University, Shillong 793022, India (Email: [email protected]) Abstract The region of northeast India boasts sizeable flora of non-native species which has ar- rived during last few centuries. Whilst several of these species have escaped in wild and naturalized, others have mingled in the flora and remain oblivious. Some species have gained dominance and replaced native flora and these are considered “invasive”. This article reports the first record of an herbaceous plant, Centaurea cyanus L. of Asteraceae family from northeast India. The plant was found in the summer of 2020 in the cam- pus of North-Eastern Hill University, Shillong while it was competing with several other non-native species on poor substratum. An extensive search in the floras of the region revealed that the plant has not been reported previously. It is probable that the plant has arrived here either as a companion with the supplies of packaged seeds of garden flow- ers procured by the residents from various sources or through some other carrier from nearby villages where it has made presence. Only time will answer if the plant remains oblivious or turns invasive. Keywords: Centaurea cyanus, cornflower, invasive species, medicinal plants. Introduction The flora of northeastern region of India has been invaded by a number of plants during the nineteenth and twentieth centuries. The invading species predominantly belong to Asteraceae and are detected only after they have gained dominance in the landscape (Shankar et al., 2011).

There have been books on the battle to transform the wilderness into an agriculturally ordered land, on the convicts, on the goldrush, on the discovery of the wealth of the continent, on most aspects of settlement, but this is the first to link the story of the discovery of the continent with the slow awareness of its unique trees, shrubs and flowers of Australia. The Flower Chain Chapter 1 The Flower Chain Begins Convict chains are associated with early British settlement of Australia, but there were also lighter chains in those grim days. Chains of flowers and seeds to be grown and classified stretched across the oceans from Botany Bay to Europe, looping back again with plants and seeds of the old world that were to Europeanise the landscape and transform it forever.

Southern Garden History Plant Lists
Southern Plant Lists Southern Garden History Society A Joint Project With The Colonial Williamsburg Foundation September 2000 1 INTRODUCTION Plants are the major component of any garden, and it is paramount to understanding the history of gardens and gardening to know the history of plants. For those interested in the garden history of the American south, the provenance of plants in our gardens is a continuing challenge. A number of years ago the Southern Garden History Society set out to create a ‘southern plant list’ featuring the dates of introduction of plants into horticulture in the South. This proved to be a daunting task, as the date of introduction of a plant into gardens along the eastern seaboard of the Middle Atlantic States was different than the date of introduction along the Gulf Coast, or the Southern Highlands. To complicate maters, a plant native to the Mississippi River valley might be brought in to a New Orleans gardens many years before it found its way into a Virginia garden. A more logical project seemed to be to assemble a broad array plant lists, with lists from each geographic region and across the spectrum of time. The project’s purpose is to bring together in one place a base of information, a data base, if you will, that will allow those interested in old gardens to determine the plants available and popular in the different regions at certain times. This manual is the fruition of a joint undertaking between the Southern Garden History Society and the Colonial Williamsburg Foundation. In choosing lists to be included, I have been rather ruthless in expecting that the lists be specific to a place and a time.

Okay* and K. Demir 1Department of Horticulture, Faculty of Agriculture, Ankara University, 06110 Ankara-Turkey. Accepted 9 August, 2010 Centaurea tchihatcheffii Fisch. and Mey., is a critically endangered endemic species, which grows on limited area around Golbasi district of Ankara province. It has attractive pink, red, purple flowers, the colours of which change with maturation. It has a high potential as out door ornamental plant and as cut flower. Its natural habitat is continuously on decrease because of uncontrolled plucking, intense construction activities and urbanization. The most important reason why the generation of the species is endangered is strong anthropogenic pressure. Therefore, the protection of this plant is of great importance. Study of propagation possibilities for the protection of this species, is of primary importance. This paper reviews C. tchihatcheffii, propagation studies. Key words: Critically endangered endemic (CR), propagation, Centaurea tchihatcheffii Fisch. and Mey. INTRODUCTION The floristic richness and diversity of a country gains extinction. Turkish laws ban trade in critically endangered importance with its number of rare and endemic „critically species, however, due to loopholes in the law, the flowers endangered (CR)‟ plant species (Ekim et al., 2000; IUCN, of C. tchihatcheffi are collected for illegal use in cut flower 2001; Vural, 2006).
