Product Details

With long, sturdy stems, these bright, 4"–6" flowers are great for colorful, long-lasting bouquets. Zinnias are a customer favorite and so easy to grow from seed. Once they begin to bloom, they bloom and bloom endlessly until frost! 'Giant Purple' is heat tolerant and disease resistant. Zinnias are edible, but have little flavor. The colorful flowers can make a pretty garnish to salads, desserts, cold drinks, or serving trays. (The flower's central disk, while edible, can be bitter.)

    The seeds that I have purchased from BI are my favorite seeds. This was my first year, trying flowers, and it felt almost full proof with these seeds. I bought a variety of zinnias and all of them turned out beautiful.
