What do sunflower seedlings look like

The giant sunflower can grow up and over 6 feet tall and their flower heads are majestically large. I have based this general growth timeline observing the sunflowers I grow in my own garden.

Depending on your growing conditions you might find a slight variation in some of the stages of growth. I usually plant the sunflower seeds I have carefully stored from my previous years harvesting. The seed is the dormant undeveloped stage of the plant. This is where the life cycle is waiting to begin. The sunflower seed, with its shell on, is a single dried out fruit of a plant in its whole form. In botanical terms it is called a cypsela. Within this whole seed is all the nutrients and genetic information needed to grow another sunflower plant.

This is the first stage of the seeds awakened life. Underneath the soil, out of sight, the wispy roots reach out and a developing shoot pushes its way to the surface of the soil, looking for sunlight. Our seedling has become a young sunflower plant. This is its development stage to gain as much growth as it can. If you have started your seeds off indoors then the time will come to harden them off and transfer them to their growing site outside.

This usually happens towards the end of spring when the last of the harsh weather has gone. The newly sprouted sunflower usually has 2 baby leaves on it and quickly grows many more as the stem starts to get taller.

The first few sets of sunflower leaves are usually oval in shape but as more leaves come they look like the heart shaped leaves of a mature sunflower, only smaller. The young plant starts to develop rapidly, getting as strong and tall as it can. You can find out how this amazing process works here.

Our sunflower plant is still growing and our bud is trying to get all the hours of sunlight it can in order to get as much energy for the bud to develop and enlarge. The way our sunflower does this is by following the sun. This is also the stage to keep your sunflower hydrated. Regular watering is so important for the budding and flowering stage of its life, so it can grow strong and big.

With all the care we have given our sunflower the bud has grown as big as it can and starts to flower. Our sunflower has now reached its blooming stage and gently opens its petals. With all its glory it shows off to the world. We can enjoy this wondrous sight for a few weeks. In all its petaled gloriousness our sunflower welcomes pollinators to visit the thousands of nectar filled disc florets that are located within the large brown center circle.

The pollinators, mainly bees, sip on the nectar, while pollon gets stuck on their fluffy bodies. They transfer this pollen to another flower which starts the pollination and fertilization process. Sunflowers pollinate in the usual two ways, but they also have a mysterious fail safe mechanism to ensure pollination and fertilisation does happen. This stage of our sunflower is fascinating in itself. The main object of its whole life cycle has come to this, producing as many healthy seeds as it can.

The back of the sunflowers head starts to turn yellow, this is perfectly natural tells us that the seeds are ripening. This process could last up to days depending on the variety and conditions. The ripening seeds attract birds, animals and bugs to feast on. Watching these critters enjoy my sunflowers is a guilty pleasure of mine. At this stage the sunflowers head starts to droop and turn brown. If you have decided to harvest the seeds for feeding your pets , or yourself, or to store for winter feed for the wildlife , then this will be a good time to do so.

You can do this by cutting the stem about 4 inches below the sunflowers head, store it upside down in a breathable bag in a dry place away from wildlife and pets. Then, come the warmth of the following spring the seeds wake up, they start to germinate and a sunflower seedling will appear, and we can once again marvel in the 8 wonderful stages of our sunflowers growth timeline. The chart below represents a visual representation of the 8 Sunflower Growth Timeline stages as a quick reference guide for you.

I hope it helps. I hope this has been helpful and a fascinating read to you as it has been for me to write. I bimble about my garden enjoying the fruits of my labour and sometimes take for granted the marvels of mother nature.

Most of my sunflowers respond heliotropically as you stated here, and have been blooming sporadically throughout the season.

I love your idea about planting in rounds so they keep blooming through the fall where I'm at they would probably be done by mid September. I did not do that this year, but probably will next year! Hoping to use seeds from this year's flowers to grow next year's : Thanks for the good read and the insight! The reason I am here reading up on how to grow these is because these and hemp are both very good at removing toxins from the land.

If someone wants to grow organic food but their land tests positive for chemicals not allowed in organic food, they can grow sunflowers or hemp and they will pull a vast number of harmful chemicals out of the ground and store them. I would not consume the seeds without having them tested for the chemicals first, but I just thought people might want to know that these are not only beautiful but they can serve a real purpose in healing the land.

I am growing sunflowers and want to harvest and save the seeds for next year. If I cut the heads and put them in water inside, will they continue "growing" and developing seeds, or do I need to leave the heads on the plant until the season is over? It would be nice to have beautiful flowers in the house, but I don't want to sacrifice the seeds. As per above, for indoor bouquets, cut the main stem just before its flower bud has a chance to open to encourage side blooms.

We have an 18 footer that came up in the middle of the tomatoes this summer. I assume it was squirrel-planted. It towers over everything. I call it our personal jack and the beanstalk.

This is my first time growing sunflowers and they are doing well. They are from 5 to 7 feet tall and still growing. They have been fine up to about two weeks ago. They are now getting holes in the leaves, like something is eating them. Now I have found earwigs and small yellow flies on the plants. Do these help or hinder. What can I do? Hi William, It could be sunflower beatles or grasshoppers eating your sunflower leaves.

However, once your sunflowers are that tall, there is no real worry of them harming the growth of the plants. The plants can survive and even thrive despite some foliage being eaten. We hope this helps! We garden in a very windy spot. This article says to avoid winy places for growing sunflowers, which is the one part of which I disagree. Sunflowers love the wind!

Thanks to the wind, our sunflowers grow massive and impressive looking trunks like trees. A very few get knocked over when the soil is wet, and a hard wind comes through, but they just make up for it and grow stronger with a bend at the base. By the end of summer, the thick stems tower overhead like the canopy of a magnificent flower forest.

We took a road trip and after passing the mountains surounding the capital we found ourselves driving through miles and miles of sunflowers. I asked a Turkish friend about them when we got back into town and was told that they harvested the heads for seeds and oil and the white pulp in the stems they used to fabricate Insulation. Some have told me to cut the seed head off my monsters when birds start eating them.

It's cold here and I didn't have alot of room in the house so I put them in paper bags cut in pieces each and put them in the shed. The backs have turned black on some and some of the seeds have mold on them. Can they still be harvested and eaten? Do I need to bring them in where it's warmer or is it too late? We would not advise eating the moldy seeds. Unfortunately, if the others were kept in the same bag, they may have mold spores on them despite looking alright. Planted six seeds this spring.

Five survived and now are from eight to ten feet tall. One of them has a head about ten inches in diameter and drooping over. What, if anything do I do with it?

My first time for Sunflowers. What do I do with them this fall? We have been stationed in Germany for almost a year. I decided to buy some bags of sunflower seeds for the birds and one of the seeds germinated in my flower bed. I left it alone to see if it would grow. It is now approximately 4 feet tall. The interesting thing is that it is one stalk with 3 flower heads on it. Is this a normal thing? One head is now opened, second is half opened and 3rd is just starting to open.

I can send a photo if you need to see it. Yes, this is normal! Many sunflower varieties produce more than one flower, while others typically the giant ones only produce one. Planted year old seeds.

Plants instead of growing leaves on the main stock new arms with leaves and very small flowers grow. First time this has happened to me. Plants are six feet tall now, and very bushy, four feet wide. Unless the main stem was somehow damaged…? Sunflowers will branch out if damaged. We got a small package of sunflowers in July to plant. Will they last until next year or should we go ahead and plant them now and try to retrieve some of the seeds for next year?

Sunflower seeds will last until next spring without issue, as long as they are kept in a cool, dry place. Skip to main content. You are here Gardening » Growing Guides.

How to Plant, Grow, and Care for Sunflowers. By Catherine Boeckmann. Create a drill a shallow depression in the soil for each seed with a 10cm gap between each one; the drills should be about 12mm deep.

Carefully place the seeds into the drill and cover with soil. Once the sunflowers become taller, use a cane to support the stems by loosely tying the stem to the cane with some string.
