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.)

Stunning and Fast Growing

5 out of 5 stars Jul 9, 2020
These are so beautiful and the pollinators love them! I got these, the Persian carpet, giants, and northern lights blend and they are so perfect.
Jenna from NC

large blooms!

This is such a pretty color in the garden and in the vase. It's a big plant even after taking cuttings all season. It wilts in the hot afternoon Texas sun but recovers the next day with regular watering. I have powdery mildew in my area so the bottom half of the plants are suffering. I strip the leaves off before I take them inside. The petals can really get stacked on these. So lovely.

These are one of the most satisfying plants to start from seed, ever. They sprout quickly and grow into stunning, tall, heat-tolerant flowering plants. The butterflies and hummingbirds are regularly at these outside my house. They really are a superior seed from BI, and I'm not exaggerating by saying they will bring a TON of joy to whoever plants them. These would be perfect for kids to plant, too, as they're easy to plant, sprout quickly, and are tough. Just GORGEOUS-- my whole neighborhood is LOVING seeing them in my yard, too!

Beautiful blooms

These are stunning zinnias; they have a rich purple color with a pale green center as the begin to open. They have done very well through the hot summer. Will definitely plant again.

Easy and stunning

High germination rate. Grew quickly and weren't finicky. In my soil, they were a full range of pinks. The butterflies and hummingbirds loved them. Eventually Caterpillars munched on the leaves. Will definitely buy again. Combined with the Cut & Come Again variety. Just sat back and watched the pollinator show.

The Easiest Flower You'll Ever Grow

5 out of 5 stars Oct 16, 2020
Wow. These are vibrant beauties!! Bought them back in the spring and have been continually impressed all summer, and now fall, with them. They bloom endlessly, with each flower being full bodied and absolutely stunning. They're super heat tolerant (I live in Texas and these babies survived full sun with temperatures upwards of 100), and have had very little pest problems compared to other plants in my garden. Cannot recommend these highly enough. I've been deadheading them, and throwing the spent blooms over my fence and into the pasture and they completely reseeded! They are blooming and flourishing in my pasture just as well as they are thriving in my garden! Amazing!! They've completely converted me into a Zinnia lover!!

not one flower

We had nothing come up from this packet. Not one flower.
virginia Sattler-Reimer from MN
Owner Response: Hi Virginia, We are sorry you saw poor germination from this seed packet. Zinnias require warm soil to germinate, 70-80 degrees F is ideal. Below this threshold germination will fail unfortunately for this semi-tropical species. Since soil temperature lags behind air temperature the soil doesn't usually reach this temperature range until 2 to 4 weeks after your average last frost date. Rest assured, that our seed lots are tested regularly to ensure we are packing seeds that exceed both federal and our own standards for germination. We hope this information was helpful. A customer service agent will be contacting you to help troubleshoot the issue further.

Beautiful blooms

These are my new favorite zinnia. The flowers were a vivid, deep purple and almost as big as my hand. They thrived in our hot, dry Texas climate all summer long. They are tall and may not work in all landscapes but will always have a place in mine.
Jennifer M from TX

Gorgeous and hardy

These giant purple Zinnias are a show stopper. While everything else was suffering in the hot Texas sun, these flourished. I will buy these again and highly recommend them.
Jennifer from TX

Easy to grow & beautiful!

These flowers are absolutely stunning! I bought these to plant in spring but decided to throw a few seeds in the bed to see what would happen. They germinated fast.

So disappointed!

Ordered "Giant Purple" zinnia, & they are very hot pink. I was so looking forward to the purple in the photo. Even if they were a different purple that would have been fine, as I understand how computer monitors differ. But there isn't anything purple about these!
Lynette from RI
Owner Response: Hi Lynette, We are sorry you are disappointed with this cultivar. We would like to understand more about the color issue and will be following up via email.

Not happy with the color

The blooms are very large, but the blooms are magenta not purple. So the blooms did not fit the border as planned

Giant Purple Zinnia

4 out of 5 stars Nov 5, 2021
Again, I would not consider these 'giant'. They were a beautiful purple, and as I noted in other Zinnias I rated, these did not get the mildew on the bottom leaves which is a plus.
Keri from CO
Owner Response: Hi Keri, In ideal conditions, you can expect 4"-6" blooms.

Giant purple zinnias

4 out of 5 stars Mar 27, 2022
Good germination and growth, but my grandmother's heirloom zinnias were the size of saucers while these were more like silver dollar sized (give or take). Definitely not giant, but still attracted pollinators and provided beauty in the garden. Pretty uniform purple color though.
Jo from KS
Owner Response: Hi Jo, In ideal conditions, these zinnia blooms reach 4-6" in width. Plant spacing and soil nutrients are important factors that impact flower size.
