Not only will sunflowers add an instant pop of color to your flower garden, but they also have several physical benefits for the soil and plants around them. First, they attract bees to your garden, which pollinate your other plants and help them thrive.

And don’t forget about the edible seeds for their healthy fats, sunflower oil, and beautiful flowers you can collect as your sunflowers grow!

Sunflowers are truly remarkable plants—and not just due to their towering height. They are heliotropic, meaning they turn themselves throughout the day to constantly face the sun. Hence, it’s no surprise that such an intriguing plant successfully attracts bees and birds. While the bees help pollinate your other flowers, the birds may eat sunflower seeds or other produce, so you’ll want to keep a close eye on your garden.
Sunflowers come in many shapes and sizes, so you should have an idea of what you want before purchasing your seeds. Some sunflowers stay small and pollen-free, making them favorites for bouquets and indoor displays. Others use sunflower seed kernels for their health benefits. While dry roasted sunflower seeds are crunchy snacks with healthy fats, remember to eat sunflower seeds in moderation. Sunflower seeds are also considered one of the best food source of vitamin E. Furthermore, sunflower seeds are pressed to form sunflower oil.
Choosing the best sunflower seeds may not be as easy as you think. There are a lot of factors to consider as getting the wrong seed might jeopardize the health of your other plants. We choose only the best sunflower seeds in the product review above to ensure that you buy a quality product. Here’s what you need to know before buying sunflower seeds for your garden.
What Are the Pros and Cons of Planting Sunflowers in My Garden?
Sunflowers can provide much-needed shade for other plants in your garden, thanks to their height and head size. A group of sunflowers planted close together form a natural wall, which is a unique alternative to hedges or bushes that normally hide the unappealing parts of your landscape.
Sunflower plants also help prevent weeds from overtaking your garden, since their seeds contain a natural weed-killing chemical. Moreover, sunflower roots filter heavy metals out of your soil, leaving behind a healthier environment for your various plants.
The natural weedkillers in sunflowers have their drawbacks, though, as they can stunt the growth of plants in close proximity. In addition, sunflowers attract birds and squirrels, leading them right to your other flowers, fruits, and vegetables. Strong winds may knock over sunflowers, possibly uprooting them and other plants around them. For these reasons, you may want to establish your sunflowers a little farther away from your other plants.

Q: Do sunflowers grow back each year?
