I have been trying to grow Cactus Dahlias for years. I thought I could grow them in the ground, in amended soil. I planted tubers and thought “I will have flowers in eight weeks” Ha. This was four or five years ago. The tubers would sprout, put out a few leaves, and then die back down. A couple of times a year this happened until finally a passing critter dug them up and ate them. They hung around the garden for a few years, I kept hoping for flowers, but never got so much as a bud.
This spring I ordered some Labyrinth Cactus Dahlia tubers. I was shipped single red Dahlias and these replacement tubers are supposed to be Labyrinth. I was expecting long stemmed peach and pink mixed flowers…that is not this. This is the shortest stemmed flower I have ever cut. Maybe and inch and a half of stem and I accidentally clipped a bud while trying to cut the flower. These are pretty whatever they are, Cactus Dahlias, but not Labyrinth. Oh, well. I am still thrilled with the flower. All the stems are seemingly very short so my dreams of an overflowing bowl of Dahlias are dashed…
I am growing these in plastic pots. The tubers were planted about two months ago, so the original thought of having Dahlias in eight weeks is about right. The red singles I planted in March have burned out and gone dormant (or perished in the heat?)
A close up:

In pale purple, the Dahlia and bud. Green Envy Zinnias are hanging over the side. The foliage is Asparagus Fern and Sweet Begonia leaves. The vase is a thrift store find.
