Dahlia Tubers

My garden is done for the 2014 season. I dug up the dahlias that I loved this year, and photos of them in bloom and the tubers produced are below.

The first two photos are of a purple dahlia that was grown from seed. These were grown in an area that was amended with sand and compost in my heavy clay garden. They bloomed profusely, but did not bud until a few weeks after the dahlias grown from purchased tubers. Big, fluffy cloud like booms. I’m curious to know what dahlia form these are considered. Are they similar to any named varieties?

Comparison of the yellow and purple dahlias grown from seed

These were interesting in that the purple was a typical dahlia clump, while the yellow had distinct stems with different clumps that were already divided — score!

I was hesitant to grow dahlias from seed because I was unsure of the blooms that would result, but I am so happy I did! The pompon dahlias were some of the earliest to start budding and blooming. The larger cloud like purple and yellow plants started blooming later, I still had blooms into November!

After their leaves browned I dug the roots of the yellow and purple variety to save them. I was very impressed with the tuber quality that resulted from these seed grown dahlias and I’m excited to have more known tubers for next year.

The smaller dahlias I left in the ground to overwinter. I doubt they will come back in my zone 5b Chicago garden and I kind of hope they don’t. I’m excited to start another row from seed next year! Hopefully I’ll be in for a few more nice surprises.

Up next is the only purchased tuber I planted — Wittem. I chose this variety to use for my wedding. I’m sure I’ll have a much more in depth post in the future.

I started with 6 clumps in the spring and I’m not sure how many I have for next year, but wow did they multiply! I’m going to clean them up best I can and store them in a cool spot in the basement. Will divide in the spring and report back.

These tubers were fat! Surprised they did so well in the heavy clay, monster clump not pictured

 

Not sure I’ll put dahlias I intend to dig up in they clay again as it was a chore to dig them out. Very nice tubers for next year.

It was a great first year of growing dahlias and I’ll continue, but I don’t think they’ll get as large of a chunk in my garden in the future.  I will give away a few of the clumps to friends and family. I do hope to invest in a lotus flowering variety for next year and perhaps some consistent bedding varieties.  My number one priority next year is fragrance, which dahlia’s unfortunately are completely void of. Their foliage has a distinctive scent I don’t dislike, but it’s not floral.

 

Pompon Dahlias

Grown from seed. Prolific. I am going to attempt to overwinter the tubers produced. In my zone 5b garden… Risky but I’m not too concerned. If it works it’s good to know. If it doesn’t I’m not out much.
