Description

The plant has an erect rough-hairy stem, reaching typical heights of 3 metres (10 feet). The tallest sunflower on record achieved 9.17m (30ft 1in). [3] Sunflower leaves are broad, coarsely toothed, rough and mostly alternate; those near the bottom are largest and commonly heart-shaped. [4] Flower [ edit ] Sunflowers make long-lasting cut flowerstoo.The smaller-flowered types, with their abundant blooms over many months,are particularly popular with flower arrangers. The more unusual colours, including chocolate brown, cream and dark red, are particularly sought-after. How to choose sunflowers Perennial sunflowers are best planted in spring or autumn, when the soil is warm and damp. They can also be planted in summer if bought in flower, although they will need regular watering to help them get established successfully. This cultivar seems to be especially attractive to bees, butterflies and birds. 10) H. annuus‘Kong’

When growth of the flower stalk stops and the flower is mature, the heliotropism also stops and the flower faces east from that moment onward. This eastward orientation allows rapid warming in the morning and, as a result, an increase in pollinator visits. [9] Sunflowers do not have a pulvinus below their inflorescence. A pulvinus is a flexible segment in the leaf stalks (petiole) of some plant species and functions as a 'joint'. It effectuates leaf motion due to reversible changes in turgor pressure, which occurs without growth. The sensitive plant's closing leaves are a good example of reversible leaf movement via pulvinuli. This tough annual self-seeds readily and has become naturalised in many geographic regions outside North America. When they have withered, they form sunflower seeds which can be used for all your culinary needs and as a source of food for the wildlife in your garden. Giant sunflowers that will reachover 2.4m (8ft) tall are best planted next to the house, so they can be attached to the wall for support. Bamboo canes won’t usually be long or strong enough to support themWhen you’re growing a sunflower strictly for ornamental purposes, it’s okay if it gets a little dehydrated – as long as it blooms. Most of us are familiar with the traditional tall sunflower withits large yellow daisy-like bloom, but there’s far more to sunflowers than that. They come in various forms, both short-lived annuals and longer-lived clump-forming perennials. The plant was first domesticated in the Americas. Sunflower seeds were brought to Europe from the Americas in the 16th century, where, along with sunflower oil, they became a widespread cooking ingredient. With time, the bulk of industrial-scale production has shifted to Eastern Europe, and (as of 2020 [update]) Russia and Ukraine together produce over half of worldwide seed production. Technically qualifying as a dwarf variety at 75cm tall, ‘Sunsation Yellow’ boasts the plus point of a relatively long blooming season that goes well into autumn. It has very bright sunny yellow rays centred by an amber disc so that the entire flower is rather lighter in shade than those of most varieties. 6) H. annuus‘Little Leo’

When growingfor cut flowers, you may prefer to plant them in a separate cut-flower bed or on a veg plotFor example, as the flowers are a source of nectar, they will draw butterflies and bees to your garden in abundance. The flowers vary in size too, from huge dinner plates to small teacups, and not just traditional yellow, butvariousshades of cream, red, orange and brown too. When they’re newly germinated, they’ll need a good soak every day that it doesn’t rain for at least a week or two. Reaching a staggering height of about 4.5m, which is taller than some trees, the aptly-named ‘Giraffe’ is a giant sunflower.

It produces a gorgeous flower, is prolific and floriferous, and it blooms all summer and autumn long! About 90cm tall, ‘Garden Statement’ is a relatively new cultivar that is rapidly gaining popularity. The reason is that it produces fantastic flowers that are of a riveting coppery red hue with a distinctly velvety sheen. 14) H. annuus‘Ruby Sunset’ Annual sunflowers are usually grown from seed, sown indoors in spring (see Propagating, below). Keep them on a sunny windowsill or in a greenhouseuntil late spring or early summer, then plant outside once the soil is warming up and there is no risk of frost. Harden themoff thoroughly first, to acclimatise them to outdoor conditions. As their name suggests, sunflowers love a sunny spot.To fuel their vigorous growth, they also like rich soil with plenty of added organic matter, such as garden compost. Dig this into the whole planting area, rather than just into the planting hole, especially when planting long-lived perennial types, to encourage their roots to spread out. Annual sunflowersThis alignment results from heliotropism in an earlier development stage, the young flower stage, before full maturity of flower heads ( anthesis). [8] Young sunflowers orient themselves in the direction of the sun. At dawn the head of the flower faces east and moves west throughout the day. When sunflowers reach full maturity they no longer follow the sun, and continuously face east. Young flowers reorient overnight to face east in anticipation of the morning. Their heliotropic motion is a circadian rhythm, synchronized by the sun, which continues if the sun disappears on cloudy days or if plants are moved to constant light. [9] They are able to regulate their circadian rhythm in response to the blue-light emitted by a light source. [9] If a sunflower plant in the bud stage is rotated 180°, the bud will be turning away from the sun for a few days, as resynchronization with the sun takes time. [10] But if you’re planning to harvest the seeds, protect the blooms throughout the growing season. The best idea is to establish any scare tactics ahead of the birds discovering this tasty crop.
