Surprising Success: Growing Dahlias from Seeds in Florida

When my daughter gifted me a packet of Dahlia seeds, I had little hope that the plants would grow. I often feel that way about “normal” things trying to grow in this jungle. I live in zone 9b.

My daughter was a little bit obsessed with the Floret flower farm. It was (is?) a show on one of the networks, and focused on a young couple who began a huge flower farm in Washington state.

Their farm is impressive, and they have turned it into a thriving flower business. From what I can tell, the husband is behind the scenes doing all the heavy lifting, while his wife, Erin, does the social stuff, writing of books, and poses for photos. Photography of her holding humongous bouquets appears to be their trademark.

Growing From Dahlia Seeds, Year One

I put the dahlia seeds into a shallow clay pot. I’d never grown dahlias, and had no idea how to do it. I’d always heard that dahlias were tough to grow. Between that and the fact that the seeds came from Washington, I honestly did not think anything would happen.

When I lived in New Hampshire a local farm sold them out of the greenhouse. Greenhouse plants generally mean they like it warm. But I bought a dahlia plant and put it in my yard. It died. This added to my doubts.

The Floret seeds came with a little booklet full of information about growing Dahlias, Zinnias, and Celosia. These three were the seed types my daughter sent. Floret also has a whole page online about How to Grow Dahlias From Seed.

So the first year my seeds became small, scraggly dahlia plants. They grew about 4-5 inches tall in the shallow pot. When the season was over I pulled them up. They had some tubers at the bottom. Surprise, surprise!

In the booklet that came with the seeds, Erin (the writer) said that she stores her tubers in a cool place in ziplock bags. I was not going to bother with that. All I had was possibly the fridge for storage. So I yanked out the little plants with their tubers and tossed them into the compost barrel. I know, I am awful.

Unexpected Dahlia Plants, Year Two

After months went by and I grew my “winter” crops here in Florida, it was time to ready the gardens for Spring growing. As I dug through the dirt in my compost bin, I found the dahlia tubers just laying at the side! They still looked okay, and I figured I’d just put them into the ground for the heck of it. And they grew. I never even marked where they were planted and now I am only guessing about some of them. Like the photo in the center below. I’m pretty sure it’s a Dahlia.

I now have some pretty nice dahlia plants growing! One is tall, and flowering with pale yellow flowers. I had expected the fluffy type bloom, but got this star shaped flower.

Year two, growing the tubers, is working out much better. I plan to leave the plants growing in the ground and see what happens over winter. If they go dormant and need temperatures that are not freezing, the plants should be okay. The ones in pots might just need transplanting to larger pots until next year. It is very hot to be gardening in July.

Flower Books From Floret

Amazon sells books all about the Floret flower farm (paid link). If nothing else, they are full of beautiful photos. Her books will show you how to grow, harvest, save seeds, and make arrangements from the flowers you grow. I do not have any of her books, and personally, I am not interested. I do not cut my measly little selection of flowers to make floral arrangements. I leave the flowers for the bees and butterflies.

Remember that the books are written by a woman who has a huge area of space, with greenhouses, and lots of help. Also, she lives in Washington, which is about as far (in the US) from Florida as it gets.

My Other Floret Flower Seeds

Along with the Dahlia seeds, I also received Zinnia and Celosia seeds. I grew the Zinnias and they were unimpressive. The colors were a pale blush pink. Zinnias, in my opinion, should be bold in color. I love my deep reds, bright oranges, and stunning pinks. I did not save any Floret zinnia seeds. This year I planted from my own saved seeds, and bought a few others.

However, the Celosia were another story! Holy cow, these things are prolific. Celosia is another plant I was totally unfamiliar with, and let me tell you, they are beasts! Apparently they love the Florida climate and the bees LOVE the fluffy flowers. I will be writing a page about them soon.

In Conclusion

The secret to successfully growing things is this: Toss seeds somewhere, ignore them, treat them badly, expect nothing, and see spectacular results. (I am only partly kidding.)
