Are Zinnias Worth Growing on Your Flower Farm?

Zinnias are a staple in many flower farms, and for good reason. They’re bright, cheerful, and incredibly easy to grow, making them a favorite for both seasoned flower farmers and beginners. In this episode of the Flower Farmer Forum podcast, I dive into the pros and cons of growing zinnias, from their impressive yield to their finicky storage needs. If you’ve been debating whether to add zinnias to your farm, here’s everything you need to know.

The Pros of Growing Zinnias

Zinnias are one of the easiest flowers to grow from seed. They thrive in hot weather, making them a perfect choice for summer production. Once they start blooming, they produce an abundance of stems, ensuring a high yield with minimal effort. Their wide range of vibrant colors and unique petal shapes add volume and texture to any floral arrangement. Plus, they’re a fantastic option for you-pick farms because customers are naturally drawn to their bright, happy appearance.

Another advantage is their versatility. Whether you’re making casual market bouquets or larger mixed arrangements, zinnias add a pop of color and a wildflower-like charm that customers love. And when harvested at the right time using the wiggle test—where you gently shake the stem to ensure it’s firm rather than floppy—they hold up well in arrangements.

The Cons of Growing Zinnias

While zinnias are easy to grow, they do have some quirks that can be frustrating for flower farmers. One major downside is their tendency to bend or twist, which can make them tricky to arrange in structured bouquets. Some varieties are more prone to this than others, so choosing the right type for your needs is crucial.

Another challenge is their water quality issues. Zinnias can turn vase water slimy quickly, which shortens their vase life if not properly managed. Regular water changes and flower food can help, but it’s something to be aware of when selling to customers who may not be as diligent about vase care.

Perhaps the biggest downside is their poor performance in coolers. Unlike many flowers that thrive in cold storage, zinnias tend to suffer when refrigerated, making them a poor choice for wedding and event work. If your farm primarily supplies florists or large events, this is an important factor to consider.

Are Zinnias Worth It?

Despite their quirks, zinnias remain one of the most productive and profitable flowers to grow. They’re a great option for farmers’ markets, CSA bouquets, and you-pick farms, where their cheerful appearance and easy growth make them a customer favorite. However, if your farm focuses heavily on wedding work or high-end floral design, you may want to consider their limitations before committing to large plantings.

At the end of the day, zinnias are a fantastic addition to most flower farms—just be mindful of their storage and vase life challenges. With the right care and variety selection, they can be a reliable, colorful workhorse in your summer flower lineup.
