Advantages & Disadvantages of Various Types of Sunflowers

Sunflowers are a popular crop, and a great way for vegetable growers to experiment with adding flowers to the product mix. With more than 50 cultivars to choose from, getting started with sunflowers can be a bit daunting. This article explains basic advantages and disadvantages of the various types and offers some recommendations for choosing the sunflower varieties that best suit your needs and preferences.

Top Quick-Pick Sunflowers

For those in a rush I'll cut to the chase: If I had to pick the easiest, most reliable sunflowers for the beginning grower as well as for no-nonsense sucession-planting and harvesting, I would recommend the 'Sunrich' series or the 'Pro Cut' series. I explain why below, but first I'd like to review some sunflower basics.

The 2 Primary Types of Sunflowers

There are two basic types of cut-flower sunflowers:

  1. Single-stem types
  2. Branching types

These two types are so different from one another that I almost think of them as different crops. I grow the single-stem types because they are preferred in my market, but I can see where some growers would do better with the branching types. Here are some pros and cons of each type.

The Sunrich and ProCut Series are single-stem sunflower varieties suited to pros and beginners alike
The 'Sunrich' series and 'ProCut' series are well-suited to beginners and pros alike.

Single-stem varieties, including the Sunrich and ProCut series, are pollenless hybrids, which means they do not drop pollen on furniture, tablecloths, and clothing, as non-hybrid sunflowers do. While pollenless varieties do still produce nectar, and thus sustain nectar-feeding organisms such as butterflies and hoverflies, all bees need both nectar and pollen to survive. Pollenless sunflower varieties planted in proximity to regular, bisexual sunflowers are likely to be visited and pollinated to some extent by pollinators that have visited the regular flowers. And, if left to mature on the stem rather than being cut, they will also be likely to produce some seed.

Continuing on the plus side for single-stem sunflowers, many of these varieties are really quick to bloom, needing just 60 days from seeding date to reach harvestability. In addition, there is a good selection of day-neutral single-stem varieties that can be grown in a hoophouse early in spring or late in fall. (See our article on how day length affects flowering for more detail.)

Single-stemmed plants are more mutable than branching types in regard to the size of the flower you can produce. You can crowd the plants into 6" x 6" spacing to produce smaller, bouquet-sized flowers; or you can space them 12" apart to produce dinner-plate-sized flowers. (See our video on planning, spacing, and sequencing tips for sunflowers to learn more about how spacing influences bloom size.)

Single-stem varieties additionally have strong, thick stems and flowers of substance that make a statement and fill out a bouquet, which endears them to florists. And their vase life is amazing, particularly the pollenless ones — up to 2 weeks in plain water.

On the other hand, single-stem sunflowers produce just one single flower from one single seed. (Although a few cultivars may send up small secondary flowers in mid-summer, this is not the norm.) This means you need to succession-plant single-stem sunflowers every 10–14 days, all season, if you want to have a continuous supply. If you're selling your blooms, you will need to charge more for single-stemmed cuts to make a good return on your investment. You can treat this as an opportunity, nonetheless — see our 3 Sunflower Succession-Planting Programs to learn how.

Branching sunflower varieties produce numerous blooms over a long period of time, so they don't need to be succession-planted as frequently. There are numerous unusual colors among the branching varieties, including burgundy, chocolate, bronze, and bicolors. Most of the doubles (with blooms that have more than one layer of petals) are branching types. In other words, this category has a lot of pizzazz.

On the other hand, the stems on most branching sunflowers are neither as long nor as strong as those of single-stem varieties. Most need 65 days or more to bloom, and they also require a lot more space; we recommend you plant the branching types 18" apart. And their lengthier production cycle lends insects and disease more opportunity to attack the plants. Yet by growing branching types, you are at the same time sustaining the beneficial organisms that rely on them. Many branching cultivars do produce copious amounts of pollen — look for those identified as pollenless if you think this is going to be a problem for your customers. And as a group, the branching varieties are not especially long-lived in the vase, some with just 5 days of vase life.

Sun-Fill Green & Purple bring the sunflower-back look to the forefront.
The calyxes of 'SunFill™ Green' and 'SunFill™ Purple' wrap toward the front of the bloom, cloaking the flower face within a large fringe of sepals. Bred by American sunflower geneticist–breeder Tom Heaton, these varieties make superb bouquet fillers but are also remarkable on their own.

These are just the basic considerations in choosing varieties, and each year new cultivars are introduced that help to dispel the objections to each type. There are now branching varieties that bloom in 60 days and have no pollen, such as 'Buttercream' and 'Rouge Royale'; there are single-stem varieties that are fully double, such as 'Double Quick Orange'; and there are mesmerizing bicolors such as 'ProCut Red/Lemon Bicolor'.

As for my recommendation of the Sunrich and ProCut series, I see these as offering a strong sunflower with the traditional appearance that appeals to all kinds of people. Hence, they are easy to grow and sell. They are not finicky about when you grow them, and there are plenty of color choices among the two series. If you just want a basic sunflower, these series provide the perfecting starting point. And for the advanced as well as the aspirational grower, these two series form an excellent basis for sunflower succession planting and harvesting.

There are so many more sunflower varieties to explore, with single-stem, branching, tall, dwarf, pollenless, and "regular" types, as well as novel shapes, sizes, and multicolor options. Over time, you will surely want to explore other options to find new combinations that suit your needs and preferences.
