Also of a nondescript height nearing 1.5m and also producing flowers of an average size, ‘Ruby Sunset’ is also very much a special cultivar. Helianthus annuus (common sunflower) belong to the dicotyledonous category, distinguishing them from monocots. As dicots, sunflowers possess embryos with two veins, known as cotyledons, a characteristic feature that sets them apart. The veins in their leaves exhibit a net-like pattern, in contrast to monocots, which typically display parallel leaf veins. A relatively new cultivar appearing around 2018, ‘Sunbelievable Brown Eyed Girl’ took the bronze medal at that year’s Chelsea Flower Show and it is easy to see why. 1 Rice, G. (2018b, September 28).

Retrieved March 24, 2023, from https://www.rhs.org.uk/plants/plants-blogs/plants/august-2018/helianthus-annuus-sunbelievable This 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] It has light, bright, lemony-yellow rays of a crinkly texture and a disc that is a chocolate brown shade.

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. Reaching a height of around 1.5m and producing flowers of average size and which has a corresponding average blooming season, ‘Velvet Queen’ is actually a very special cultivar.Also, consider netting and supply alternative food sources.

Other than where noted, they flower through most of the summer and are annuals. 1) Helianthus annuus The plant flowers in summer. What is often called the " flower" of the sunflower is actually a "flower head" ( pseudanthium), 7.5–12.5 centimetres (3–5in) wide, [4] of numerous small individual five-petaled flowers (" florets"). The outer flowers, which resemble petals, are called ray flowers. Each "petal" consists of a ligule composed of fused petals of an asymmetrical ray flower. They are sexually sterile and may be yellow, red, orange, or other colors. The spirally arranged flowers in the center of the head are called disk flowers. These mature into fruit (sunflower "seeds"). As they are perennials, theydie down into the ground over winter and re-sprout from the base in spring.Sunflowers produce their floral reward very promptly after planting and in profusion, but they also have other pleasing characteristics.
