Sunflowers may not grow in a greenhouse because it requires constant sunlight and hence it may not grow
15 feetCertain varieties of sunflowers grow 15 feet tall, but there are varieties that grow much shorter.
Takes approx 14 - 21 days for sunflower seeds to germinate, depending on the type of S. flower, and weather & water conditions. 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.
Sunflowers love full sun, so, this will depend on what other light source it has. It may grow, but will be long and spindly. It will also grow towards the light, and if it blooms at all, the bud/flower will be quite unspectacular.
In a warm temperate climate the giant - type sunflowers take about three months from seed to flower. The miniature varieties are a bit less.
Sunflowers typically take about 80 to 120 days to mature from the time they are planted.
Sunflowers like full sun and warmth so be sure to plant them in a well lit place and they are easy to grow in the sense that you don't have to do a lot of maintenance with them and only have to water them about every three days.

first you have to find out what germination IS
Yes. Although sunflowers prefer soil that provides plenty of nutrients, they have been known to grown in sand. Ideally, however, they need richer soil, and sand is far from a healthy environment. Also, the conditions of the sand make a difference. Sunflowers cannot grow in a sandy desert, exposed to too much sun and wind, but they will grow - tentatively - in sheltered sandy positions.
The Canadian climate is not hospitable to the avocado tree, however, you can still grow an avocado tree in Canada, as long as it is in a greenhouse or other warmed enclosure. You could have a small, potted tree in your living room.
the best place to grow a sunflower is inside your house on a windowsill. make sure it receives sunlight and water Answer. The best final planting position for sunflowers,as the name suggests, is in a sunny position.
I'm a landscaper who grows sunflowers for clientel and happen to know a lot about them. sunflowers are originally thought to have come from either russia or north America. the mammoth sunflowers grow fast and become tall not because they want to be noticed but because they need to have height in order to collect sun. Furthermore as the sunflowers grow the bottom leaves naturally begin to die off as new ones emerge from the stalk. Also sunflowers prefer to be fed, while it is not necessary, they seem to flourish better in areas with a well propagated ground. given these factors a lot of scientists and biologists believe that sunflowers get they're height because they are used to growing in crowded spaces among other plants. the sunflower itself does not seem to have a long evolutionary history because they have little to no protection against wild animals (except for a thick nasty tasting stalk and plenty of height) and the only protection they have against insects is tiny hairs that grow along the stalk. most of my clients would complain of diseases on the stalk, leaves, and seed. This suggests that they're immune system is fairly weak. Most sunflowers are annuals not because they're seeds can't last the winter, but because animals such as birds and mammals constantly eat them. the smaller dwarf sunflowers usually have more volunteers than my mammoths but that could be the small seeds being hard to find by birds, people, and wild animals. another bi-product of the sunflower is sunflower seed oil. this was discovered by people when they would cut the stalks down and shave the leafs off. today it has many uses but because it drips slowly and they're is very little per plant it can't be bought easily as a wholesale item. the seeds themselves get coated in sunflower seed oil which is why they often turn a dark shady brownish color after sprouting stripes.
Most hens have small, or almost nonexistent spurs. Only occasionally will a hen grow long spurs. There are some breeds that may be more likely to grow long spurs, such as Lakenvelders. Male Lakenvelders grow very long spurs quickly, so the chances of a hen growing long spurs as well may be increased.
