You might be able to get a few to emerge from the ground and reach a few feet of height in garden spots with some shade.
In addition to getting leggy, they will have smaller flowers than those grown in full sun. Less than six hours of full sun per day could result in no flowers at all.
If you can’t get them to flower, you may have to wait until the next spring to plant them in your garden.

How much sunlight does a sunflower need?
Sunflowers need full sun; see 6-8 hours of direct sunlight per day – the more the better if you are trying to grow them to their maximum potential. Prepare your soil by digging an area of about 3 feet in diameter to a depth of 3-4 inches, if you choose a well-drained location. The flowers should be spaced at least 2 feet apart, but not more than 4 feet.
If you have a lot of flowers, you may want to plant them in a larger pot. You can also use a pot with a drainage hole in it to allow the water to drain away from the plants. Make sure that the pot is large enough to hold all of your flowers and that it has drainage holes on all sides.
It is also important that your plants are not over-watered, as too much water can damage the roots and cause the plant to wilt and die. Watering too often can lead to root rot, which can be fatal to your plant if it is not properly cared for. When watering, make sure to keep your water level as low as possible, so that you don’t have to use more water than you need.
Can sunflowers survive without sun?
Sunflowers need full sun, which means at least six hours of unfiltered sunlight every day. Sunflowers that get enough light produce abundant blooms that turn throughout the day so they are always facing the sun. It’s difficult to grow healthy sunflowers in a bright, sunny environment because they’re sunseekers.
The best way to get the most out of your sunflower seeds is to plant them in the spring, when the weather is warm and the plants are ready to bloom. If you plant your seeds in late spring or early summer, they won’t be able to produce as many flowers as they would if you planted them earlier.

Do not let the soil dry out or the plants will not be able to take the water they need to grow. If your soil is not well drained, you may have to water your plants more often than the recommended amount of time. You can also add a little bit of compost to the potting mix to help keep soil from drying out.
What month do you plant sunflowers?
When to plant the seeds. After the danger of spring frost has passed, it’s best to sow the seeds directly into the garden or outdoor containers. April and early May, this will fall in the northern half of the U.S. and Canada. Sunflower seedlings can be planted as soon as the soil is warm enough to allow the seeds to germinate.
If you plant them too early, they won’t be able to take root and you’ll have to transplant them when the weather warms enough for them to do so. The best time to plant is in late spring or early summer, when temperatures in the mid-30s to low-40s (F) are ideal for seed germination.
This is also the time of year when you can expect to see the first signs of summer blooms, such as red, white, and yellow petals, as well as early-summer leaf color changes.
Do sunflowers come back every year?
If a sunflower variety is a perennial, it will naturally return and blossom again the following year. Every year, the annual varieties must be replanted. If the heads are still attached to the stem, sunflowers will grow back if they are self-germinating. Sunflower seeds can be germinated in a variety of ways.
The most common method is to soak the seeds in warm water for a few hours, then place them in an airtight container and allow them to air-dry. Seeds can also be placed in the refrigerator for several days to allow the germination process to take place. If you are using seeds from a seed bank, you may be able to purchase them directly from the seed company.
