PREMIER SEEDS DIRECT - Cornflower - Centaurea CYANUS - Pink - 1200 Finest Seeds

Product Information

The blue color of blue cornflowers is due to the presence of protocyanin. Cornflowers are used for producing blue dye when mixed with alum. Powdery mildew is a fungal disease that can affect Centaurea cyanus, causing a white or grey powdery growth on the leaves and flowers. It can be prevented and treated by providing good air circulation around the plant, watering the plant at the base, (avoiding getting water on the leaves) and applying the fungicidal spray to the plant.

Girls, too, wore cornflowers. In England, girls wore cornflowers to show they were eligible to marry. There was a popular belief that if a girl hid a cornflower under her apron, she would marry a good bachelor. While Centaurea cyanus, commonly known as cornflower or bachelor’s button, is primarily valued for its attractive flowers, its leaves can also be used for other purposes. The leaves are edible and can be used in salads or as a cooked green vegetable. They have a slightly bitter taste and are high in vitamins A and C, as well as minerals such as potassium and calcium. Cornflowers are tough and do not dry that easily. Thus, they last longer than other delicate flowers. Their toughness and aesthetics make them a great gift for flowers. Add to a wildflower meadow: Echinacea is a great addition to a wildflower meadow or prairie-style garden, where it can be combined with other native wildflowers for a low-maintenance and beautiful landscape. Centaurea cyanus is an annual plant growing to 40–90cm tall, with grey-green branched stems. The leaves are lanceolate and 1–4cm long. The flowers are most commonly an intense blue colour and arranged in flowerheads (capitula) of 1.5–3cm diameter, with a ring of a few large, spreading ray florets surrounding a central cluster of disc florets. The blue pigment is protocyanin, which in roses is red. [4] Fruits are approx. 3.5mm long with 2–3mm long pappus bristles. [5] It flowers all summer. [6] Distribution [ edit ]

The Genus of Centaurea

In the County Clare ( VC H9) in Ireland, Centaurea cyanus is recorded in arable fields as very rare and almost extinct, [10] while in the North-East of Ireland, it was abundant before the 1930s. [11] Genetics and breeding [ edit ] Genetics [ edit ] Regular deadheading of spent flowers can encourage the plant to produce more blooms and extend the blooming period. The Kerria japonica plant produces the golden yellow cornflower. It is considered one of the most beautiful flowers native to East Asia. Yellow cornflowers also symbolize friendship and joy. Violet color Use 2- or 3-gallon (or larger) pots, with drainage holes. Spread crushed gravel in the bottom of the pots fordrainage. This plant is an annual or biennial plant, which means that it completes its life cycle in one or two years. The plant can be started from seed in the spring or fall, and will usually begin to bloom in mid-summer and continue until the first frost.

As for all ornamental plants, important goals of Centaurea cyanus breeding include the induction of phenotypic variation (e.g. in flower coloration, size and shape, foliage characteristics or plant height), higher flower yield, resistance to pests and diseases as well as tolerance to abiotic stress (e.g., extreme temperatures, drought or salinity). [15] Ecology [ edit ] Weed in arable crops [ edit ] Helmut Horn, Cord Lüllmann: Das große Honigbuch, Kosmos, Stuttgart, 3. Auflage, 2006, ISBN 3-440-10838-4, S. 31 Fertilize sparingly: Echinacea does not require heavy fertilization and can actually perform better in soil that is not too rich. A light application of balanced fertilizer in the spring can help promote healthy growth. Echinacea, commonly known as coneflower, is a genus of flowering plants in the daisy family (Asteraceae), along with daisies, sunflowers, and asters. The genus includes nine species of herbaceous perennials. Belz, Elodie; Kölliker, Mathias; Balmer, Oliver (2013).

BioControl. 58 (2): 163–173. doi: 10.1007/s10526-012-9472-0. S2CID 17117503.The cornflower ( Centaurea cyanus) belongs to the botanical family Asteraceae and the genus Centaurea. The flower owes its name to the fact that, in the past, it often drew as a weed in the fields of arable crops, particularly cereal grains. In the book “ Sylva Sylvarum” written in the seventeenth century by Francis Bacon, the cornflower is described as a flower that is seldom or never seen in other places except amongst corn. We tend to grow coneflowers in the ground as perennial plants, but you can certainly grow them in pots if the containers are deep enough for theplant’s taproot. It was also the favourite flower of Louise's son Kaiser Wilhelm I. [47] Because of its ties to royalty, authors such as Theodor Fontane have used it symbolically, often sarcastically, to comment on the social and political climate of the time. [ citation needed] There is an interesting mention of the cornflower in the Roman epic poem “Pharsalia,” written by the first-century poet Lucan. According to the poem, burning cornflowers was a way of driving away serpents. Greening of petals? Aster Yellows is transmitted by leafhoppers feed on the plant. In severe cases, the entire flower head is green. The plant will wilt and die. Remove and destroy infectedplants.

As mentioned before, the cornflower is an umbrella term that encompasses many plant species. The interesting thing, however, is that this name was derived from a very popular cultural practice. Use a sharp knife or garden shears to divide the plant into several sections, making sure that each section has at least one healthy root system and some stems. Replant each section in a well-prepared bed of soil, spacing them about 15 cm apart. Make sure to water the plants well and keep the soil moist until new growth appears. Daylilies (Hemerocallis): These plants have a similar clumping growth habit to Echinacea, and their bright orange, yellow, and red flowers provide a striking contrast to Echinacea’s purples and pinks. Blue is the most common and most popular color of cornflowers (bachelor button). The blue variant of this flower inherits almost every traditional symbolism generally ascribed to cornflowers. Mostly, the blue cornflower is seen as a symbol of freedom, vastness, courage, and hope.

White is a color of purity, innocence, and honor. White cornflowers (bachelor button) are rare and mainly found as cultivars. A white cornflower (especially when used as a gift) can be an expression of respect and a way of saying to someone how special they are.

Dig over the planting area, incorporating lots of organic matter – such as compost or planting compost, especially if the soil is heavy clay or light, well-drained sandy soil. Dig a good sized hole big enough to easily accommodate the rootball.Anti-inflammatory properties: Echinacea has been found to have anti-inflammatory effects and may help reduce inflammation in the body.

New plants may be grown each year by planting seed indoors 6-8 weeks before the last spring frost date or outdoors at the last spring frost date. In mild winter areas, seed may be planted outdoors in the fall. Skin health: Echinacea may help promote healthy skin and has been used topically to treat acne, eczema, and other skin conditions.
