Sunflowers are quite an amazing annual. They can grow in sunny, somewhat foggy, and partial shade areas. They can be anywhere between 2-14 feet in height, with one to ten flowers on a plant. They grow fast, and many tolerate substandard soils. They are also fairly drought tolerant. Many are so tough, wind does not bother them. They can be used for a privacy screen between your house and that of a neighbor. To do this, we recommend not just one row, but 2-3.
We recommend planting sunflowers in pots or a clearly defined area first. That way, when they sprout, they can be replanted to exactly their final location.
After a sunflower is done blooming, we recommend cutting the head and drying it to keep the seeds. Another way to keep the seeds for later growing is to put a thin cloth around the head and twist tie it. Or, of course if you like you can let birds eat the seeds when it is done flowering.
Below is a photo taken today in our San Francisco California garden. These sunflowers are 3-7 feet in height. They would have grown taller, but we experimented here with letting them all grow in small pots until they were 1-2 feet tall, and then planted them out. This meant they were used to being confined so now will not grow as tall. That is a good way if you like to control the size of your sunflower plants. Click here to see our favorite sunflowers.
