Zinnia Seeds

Known for their vibrant colors of pink, red, yellow, orange and purple, zinnia flowers draw attention for their long stems and varying petal arrangements (single-flowered, semi-double-flowered and double-flowered). Zinnias are low-maintenance and fast-growing, making them a favorite among home and commercial growers. They are popular summer staples and make great cut flowers for their long vase life.

Tips for Growing Zinnia Seeds

These are the ideal practices for growing the best zinnia seeds from Harris Seeds:

  • Direct Sunlight - Give your zinnia seeds about six to eight hours of direct sunlight to produce more blooms. Keep them in a bright, open location to help them grow with stronger and longer stems.
  • Consistent Watering - Consistent watering using reliable water systems will maintain your soil's moisture, but be careful not to overdo it, especially during wet seasons. Zinnias can tolerate a bit of dryness, and wet leaves increase the risk of mildew.
  • Ample Spacing - Provide enough space for each zinnia seed to promote good airflow and ensure they have enough room to grow. Plant your zinnia seeds about 9 inches apart.

Why Choose Zinnia Seeds for Your Garden?

Here's what makes Zinnia seeds a top choice among our customers:

  • They're great cut flowers. Zinnia flowers' long and sturdy stems are consistent with those of other popular cut flowers like roses, carnations and sunflowers. They look great when bundled together or placed in a tall vase. Zinnias also have a long vase life, which can last up to 10 days or longer with proper care.
  • They have a wide variety of colors. With Zinnias, you'll never run out of color combinations. You get solid colors and pastels in every variety you can think of, and then you also get bi-colors and tri-colors. You can get creative with your cut zinnia bouquets for a unique arrangement.
  • They're low maintenance. Zinnias are fast-growing and require little maintenance, allowing them to thrive against weeds. They simplify the work for growers because they require minimal fertilizing and don't need mulching. As they make for great cut flowers, the process also encourages zinnias to produce more blooms for a wonderfully continuous flowering season.
  • They have a long harvest window. Zinnias are annuals, but they make up for it with a long harvest window. They are very common during the summer season because of their productivity — the more you prune, the more they produce.
  • They're pollinator-friendly. Zinnias are an abundant source of nectar, producing a steady supply throughout the summer. Their open blooms make the nectar accessible for pollinators such as hummingbirds, bees and butterflies. The bright colors also make them visible from afar, which may explain why the tall red and hot pink varieties are particularly known for attracting many pollinators.
