Sunflowers

There's no specific shelf life for whole sunflower seeds. People have germinated sunflower seeds that are more than seven years old. Generally speaking, seeds that are less than two years old will have the greatest chance of viability.

I'm sorry i can't give you an answer but I have the same question too. :(

Lots of sun, But beware of wind in the fall. Also they will shadeout every thing north of them. So- the northern fence of the garden is ideal. The birds will eat half the nuts before their ready to dry. Plant them close to one another for support and tie a few together near the the top in the fall, for stabillitty. Tripods are most stable. Best of luck. They are magestick.

True sunflowers only occur in red, orange, and yellow varieties, with varying shades of these colors. Other plants which are sometimes called "sunflowers,"such as oxeyes, may be pure white, blue, or even purple.

sunflower seeds may cause an allergy if eaten but they are not an airborne allergy however sunflower pollen may cause an airbourne allergy

Sunflowers (Helianthus annuus) likes to live in well-drained soil, so that it has access to water, but not too much. The water will have dissolved nutrients, including minerals, that are important for the tissue growth of the sunflower plant. The absorption of water and dissolved particles is controlled by the roots, and transported by the vascular system to all parts of the plant.

Depending on where you live, it is quite possible they will still produce heads and bloom. Sunflowers can bloom at different times, with mid to late August being most common, but early to mid September still being quite possible if they were planted late and the weather stays nice.

No. They can germinate, but will soon die if there is no light.

In Afghanistan, opium poppy cultivation is prevalent, and while the seeds of the opium poppy are technically edible, they are not commonly chewed like sunflower seeds. Instead, the cultivation primarily focuses on the production of opium latex for the drug trade. The seeds themselves are often used in cooking or as animal feed, but the practice of chewing them as a snack is not a cultural norm.

Sunflowers are primary producers and occupy the first trophic level in an ecosystem. They convert sunlight into energy through photosynthesis, serving as a food source for herbivores, such as insects and birds. As plants, they play a crucial role in the energy flow of food chains.

Short answer: the sunflower lives during the warmth of late spring, summer and early fall. It dies when the seed head starts to drop seeds, or when the cold of late fall starts to bite.

The sunflower (Helianthus annuus) is a flowering annual dicot. It starts life as a seed. Germination will not begin until the soil temperature is between 55F & 60F, as the plant is sensitive to cold. The young plant will grow vegetatively for 6-8 weeks before a flower appears. Actually, the flowers are where the seed head will form, each floret representing a possible seed. It takes about a month for the seed head to mature and begin to drop its seeds. About the time of seed drop, the plant will start to wither and die. This might be mid summer, or it might not be until the cooling days of autumn.

cabbage because roses and sunflowers are flowers and cabbage is a vegtable i think i am only 10 ok so dont judge me!

The reason that sunflower seeds are usually sold by weight and not by count is because sunflower seeds do not have a uniform individual weight. One can only give a rough approximation. For example, assuming a 1 gram packet of American Giant sunflower seeds contains between 12 and 13 seeds on average, then a 10 kilogram packet would have between 120000 and 130000 seeds. Switching to a variety of sunflower seeds with smaller seeds, such as Velvet queen, you might get 30 to 35 seeds in a packet, thus averaging 300000 to 350000 seeds.

Some sunflowers take longer than others to mature---plant most when all danger of frost is past or start seed indoors and put plants outdoors in spring. The smaller varieties can be planted as late as July.

If you have a water distiller it is way much better for your sunflowers than tap water with all those chemicals used in it's treatment.

most are but some aren't.

12, I think. It did so for mine :D.

erm no ofcourse not! sunflower seeds arent from sunflowers!

yes it will help.am currently on it

According to this website - http://davesgarden.com/guides/pf/go/223/ they can grow in Seattle & Spokane.. I have seen them growing in people's yards in Port Angeles. This leads me to believe that they can be grown all over Washington state.

Sunflower is in Phylum: Magnoliophyta

There are many differences between daisy and rose seeds. Rose seeds are much smaller than a dime, varying from light to dark brown, and they grow roses. Daisy seeds are oblong thin brown seeds that grow daisy flowers.

Up to 1,000 seeds can be produced from one sunflower head. Some may produce more or less depending on the exact sunflower.
