Types of Sunflowers

Sunflowers are an enormously popular plant. They are synonymous with summer, and their bright open-faced flowers are guaranteed to make you smile. They are native to North America, though they have gained widespread popularity around the world since sunflower seeds were introduced to Europe in the 1500s.

Sunflowers are predominantly cultivated for food, with each flower being able to produce around 1,000 seeds. These seeds are edible and used in a variety of ways by people: in salads, smoothies, in bread, snacks, and more. The seeds can also be used to make sunflower oil, which is widely used cooking oil, much cheaper than olive oil. The seeds are also used as bird feed. For these purposes, the common sunflower (Helianthus annuus) is most typically used. This sunflower is probably what comes to mind when most people think of sunflowers; it is tall with a coarse and furry stem and a bright wide face.

These sunflowers grow very quickly from seed, and can often have many flower heads per stem. Their leaves bear a resemblance to weeds, and in fact, some people do consider the common sunflower to be a weed as it is so easy to grow that it will often continue to thrive even when you don’t want it to! By comparison, sunflowers are grown as decoration in private gardens usually only have one flower per stem, and there is a wide range of varieties available to choose from.

Sunflowers belong to the Helianthus genus, and this is almost a direct translation of the words ‘sun’ and ‘flower,’ with the Greek for sun flower being ‘helios,’ it is not clear why the sunflower is named as such. Some people believe it is because the flower itself bears a strong resemblance to both the color and shape of the sun, while others suggest the sunflower was named because they are heliotropes, which means that the flowers move in accordance with the movement of the sun, the flower always wanting to face up at the sun.

There are over 70 cultivars of sunflowers, which make up the entire genus. These varieties can be divided into three groups for ease: giant sunflowers, dwarf sunflowers, and colored sunflowers. You can learn more about these types of sunflowers in the sections below.

Key Points for Caring for Sunflowers

Although there are many varieties of sunflower, they tend to all have common care requirements. They are easy-to-care-for plants that need very little help to thrive, and in fact, the preparation you put into your soil and planting position will be the most important care elements of your sunflowers success, more so than anything you can do once the flowers are growing. To get the most out of your sunflowers, you can follow this care guide.

Soil

Sunflowers have long extended roots that need plenty of space to spread out, and because of this, they will do best in soil that is not too compacted and allows their roots to reach out easily. Plant your sunflower in loose soil which is not too heavy or waterlogged to meet this need.

If you are wanting your sunflower to truly thrive, you can adjust the pH of your soil. Sunflowers prefer slightly acidic soil, though they are not terribly fussy so do not worry about this too much.

Light

Sunflowers need lots of sun, and ideally should be in a position of full sun for at least eight hours a day. If their requirement for plenty of direct sun is met, they will reward you with long-lasting blooms throughout summer and sometimes in to fall.

Temperature

Sunflowers like warmth, and are heat tolerant. This means they need to grow in climates where summers are warm and long, and even very hot climates can happily grow sunflowers.

Fertilizer

Like many flowering plants, sunflowers feed heavily and so require nutrient-dense soil with plenty of organic matter. If you are concerned that your soil doesn’t contain enough nutrients, you can use organic compost to top dress your soil, or feed your plants with a liquid fertilizer. Using liquid fertilizer over other types is important for sunflowers because it is more quickly absorbed and easy to measure.

Watering

Sunflowers are drought tolerant, and though they like to receive moderate waterings, they will respond badly to overwatering. Your first line of defense to reduce the chances of your sunflowers from being overwatered is to ensure your soil is well-draining. If the soil drains well, then excess water from rain or heavy waterings won’t present a problem, as the water will drain away. Poor-draining soil will become waterlogged easily if over watered, and the plant will suffer from root rot. Typically, plants won’t survive this.

Once you have ensured your soil is well draining, the next step to prevent waterlogged soil is to simply not overwater your plant. Supply your sunflower with a reasonable amount of water, but if you are unsure, you can err on the side of caution as this plant is drought tolerant. It would rather have too little water than have too much. There is no hard and fast rule in terms of how much or how often you should water sunflowers, as this will largely be dependent on the light, temperature, and soil type, but as a general rule, you can add more water when the top layer of soil has dried out.

Shelter and Support

Sunflowers are susceptible to damage from winds, so ideally, plant them in a sheltered spot alongside walls or fences. Tall sunflowers will need support as they reach great heights to prevent them from collapsing under the weight of their large flowers.

Giant Sunflowers

These types of sunflowers are quite a sight to behold. They can grow to staggering heights, with the tallest ever recorded sunflower measuring in at 30 feet 1 inch. You can typically expect these sunflowers to reach around 10 to 12 feet, while some of the tallest varieties will exceed 16 feet. Some growers of sunflowers become obsessed with wanting to produce the tallest sunflower with the largest face, and there are many fairs and events around the world where growers come together to compete with their most impressive sunflowers.

It is sunflowers selected from this group of ‘Giant Sunflowers’ that people choose to grow competitively. These sunflowers are also popularly used in home gardens to create a striking feature along walls or fences. Due to their height, they do require support in the form of canes or ties to prevent the stems from arching or collapsing under the weight of the flower heads. These types of sunflowers are also a good option to grow with children, as they are easy to sow from seed and typically grow rapidly to a great height with impressive flowers, much to the amazement of small children.

Varieties of giant sunflowers include:

1. Skyscraper

Skyscraper Sunflower

These sunflowers are some of the tallest available, typically growing to between 12 and 14 feet. Their flower heads are equally impressive, spanning 16 inches across in a beautifully dazzling shade of bright yellow with a deep orange center. They can be sown easily from seed around four weeks before the last frost, or directly sown outside once all risk of frost has passed. They take between two and three weeks to germinate, making them an excellent project for children. They require full sun, with plenty of water in nutrient-dense soil.

2. American Giant Hybrid

American Giant Hybrid Sunflower

This variety is the beast of all sunflowers. It is the most popularly used sunflower in growing competitions, as it grows to be the tallest, typically between 10 and 16 feet, though it is not uncommon for them to grow even taller than this. The stems are chunky and sturdy, specifically developed to withstand the weight of the sunflower head, which is surprisingly not the largest flower available, measuring a humble 10 inches across. The flower face is dark brown in color, with the surrounding petals being bright yellow. They germinate in just one or two weeks during spring and bloom in summer. If grown in a row, they make an ideal screen or shade, or can simply be grown to impress your friends and family. They prefer well-draining soil, full sun, and plenty of water.

3. Russian Mammoth

Russian Mammoth Sunflower

This giant sunflower grows between 9 and 12 feet tall, with flowers growing up to 14 inches across. Though it likes full sun, it will need to be grown in a location that is sheltered from the wind to prevent its large flowers from being caught in a storm. This sunflower is especially popular with pollinators, including bees and butterflies, as well as birds and squirrels who feast on the edible seeds, while being resistant to deer. It is a great low-maintenance option, growing well in moderately fertile well-draining soil and requiring little attention after the plant has germinated. It blooms in mid to late summer with glorious blooms; the flower petals are a deep yellow, while the face is an orange-brown.

4. Giant Sungold

Golden Bear Sunflower

You can mistaken the Helianthus annuus 'Giant Sungold' for the Teddy Bear sunflower by the first look at its flower.

This is such a beautiful, low-maintenance sunflower that fit any gardens or perennial borders.

Dwarf Sunflowers

These sunflowers look like miniature versions of full-sized sunflowers and look cute in children’s gardens or in flower beds and container gardens. Their care is much the same as larger sunflowers, except for the fact that due to their smaller stature, they do not require support to stand erect. They make excellent cut flowers and tend to last a long time. Just like other types of sunflowers, there are many cultivars available with different advantages to suit any sunflower lover’s garden.

5. Elf

These impressive plants have full-sized sunflower heads on short stems. The sunflower face measures between 12 and 18 inches atop a stem measuring between one and two feet. Their compact size makes them ideal for growing in containers, and interestingly, these can also be grown indoors, but this can be much trickier than growing outside. When kept as houseplants, the seeds can be sown at any time of year, though sunflowers intended for use outside will need to be sown around three weeks before the last frost. Indoor sunflowers should be kept in continually moist but not wet soil. Pinch off new branch tips as they appear, as this will encourage more bushy growth and will also result in several flowers blooming on each stem.
