Sunflowers

first you have to find out what germination IS

im a professional sunflower grower and my sunflowers have roots 23ft deep.

In a warm temperate climate sunflowers grow from seed to flowering stage in about three months and another six weeks until the seeds mature in the flower head.This relates to the giant flowering types-some of the smaller varieties are quicker to mature.

Yes

Helianthus was native to the Americas growing in Mexico at least as far back as 2600BC.

Taken from Mexico to Spain the sunflower was popular in Europe around the 18th Century and is cultivated worldwide.

it has 6 sepals....!!

Each sunflower head can contain as many as 800 to 2000 seeds. These seeds can vary in appearance, but the most common type used for snacking is black with a white stripe pattern on the hull. These seeds are the means of sunflower reproduction, and can be planted to grow into a new sunflower the following growing season.

Sunflowers has three syllables. Sun-flow-ers.

No. Annual sunflowers die off completely once winter comes. Perennial sunflowers die down to the tap root soon after producing seeds. In other words, you can't keep a sunflower alive year round, even in a house.

The sunflower sea star (Pycnopodia helianthoides) is a large predatory starfish with 15-26 limbs called rays. They can grow up to an arm span of 1 m (3 ft.) in diameter. The colour of the sunflower starfish ranges from bright orange, yellow and red to brown and sometimes to purple, with soft, velvet-textured bodies and 16-24 arms with powerful suckers

There are many animals that eat sunflowers and their seeds. Caterpillars do feed on the actual sunflower, while deer enjoy the leaves from the plant. Humans, squirrels, many types of birds, and rabbits eat the sunflower seeds.

There are many varieties of sunflower. The largest ones (like Mammoth or Skyscraper) are usually 8 to 12 feet high if grown in the right conditions. Many colored varieties are only 6 to 8 feet tall. Some dwarf varieties will be only 6 inches tall!

I do not think Sunflowers in general have a known maximum number of flowers. Most have one main flower and several smaller ones. ---- It depends on what kind of sunflower you have. I grow ones that have many smaller blooms. Other kinds just have one GIGANTIC bloom. There are also different colors and stuff. (e.i burgundy.) Hope it helps... RangerZ

sunlight everyday and water 2 or 3 times in a day

good luck:)

Nyjer seed does not have a shell like sunflowers. Wild birds eat all of the nyjer seed.

The suffix -ivore means eater. While herbi- means herbs or plants. -Omni means all. A herbivore eats only plants and an omnivore eats anything. Humans are omnivores since we can and do eating anything. Plants like sunflowers don't eat anything. They make their own food using sunlight.
You really should learn the meaning of words like these since you come across them over and over again. They actually tell you what they mean.

you grow them when its reall hot. sunflowers love sun. if you notice when there full grown, there faces are turned to the sun.

In most instances, sunflowers will germinate within 7 to 10 days.

If the sunflowers are not a hybrid variety, then you can save the seed by cutting the flowers when the seeds are fully formed and loose in the head, drying the whole head for two or so weeks, rubbing them from the head, drying for a further couple of weeks, and replanting in the spring. you can use hybrid varieties as long as long as they are not sterile in which case you wont get any seeds anyway. you just wont get the same flower vigor and or good looks. zaf.

Yes you do. They will sprout with it on the leaves and it will get loose and fall of.

Most varieties are self-pollinating. Otherwise, you should probably just let bees do the work; they love sunflowers.

Unless you grow a dwarf type of sunflower, such as "Teddy bear" you would not grow them in pots. Most sunflowers grow tall, and become rather top-heavy. Sunflowers need lots of room to grow--including the roots, which need to spread out beneath the soil in order to anchor the plant. Even muli-stemmed sunflowers, whose individual flowers are fairly small (for a sunflower), get top-heavy because of the number of flowers on the stem. So, if you absolutely MUST grow one in a pot, select the shortest cultivar you can, and still put that in an over-sized pot. So, sunflowers grow better in the ground, but it is possible and challenging to grow them in pots.

I am not sure about heat but I do know that they grow better when they are planted in direct sunlight.
