Q. Is there a difference between Canna Durban and Canna Phaison?

Was looking at Cannas with nice leaves, inluding the “Tropicanna” cannas. Online, it seems that both Durban and Phaison are identical, but I want to be sure which is best. Suggestions?

There is quite a bit of fuss about this.

They are all Tropicannas. Depending on the nursery that got the genetics, it took the name accordingly. Essentially, they are the same, just branded by a different nursery.

Q. Canna Lily not growing

I recently received a Canna Lily as a gift. I love the plant! After researching, I found out that they should be divided from time to time. So my plant quickly became 4′. The smallest one is putting out more plants but is not growing itself. What did I do wrong?

It is very hard to say without seeing the plant, and where it sits. If the correct conditions are being provided, then they will grow easily, and without fuss.

I tried adding a photo but it wouldn't allow. Sorry for that. They're all in pots, on South side of my home. Some morning sun but almost all afternoon amd early evening sun. I live in Zone 9a. 2wks ago I was given 6 more, 3 green and 3 maroon leaded. The 4 I originally started with are green. All of them are growing new leaves, 3 have flowered with 1 flowering a 2nd time, 5 of them are spreading new growth in their pot but 2 of them are exactly the same when I received them. Not dying or wilting or changing colors, which I guess is a good thing, but strange that those 2 are about 1ft talk amd have stalled. The 1 with sprouting to planting

Q. canna indicas are not doing well

The lower leaves of my canna indicas are dying, turning brown and then wilting. Two months ago, all the leaves were robust and green as green can be. What is going on.

Looks like canna rhizome rot. I notice too very wet conditions in the soil around them.

Q. Canna lily replanted

This is the third year I pulled up the Canna roots and bulbs and replanted in the spring. Originally the where different colors. They all have morphed into a rosy orange color with very small petals. They no longer look like different colored irises. I wonder why.

They definitely won't turn into an iris, but they can revert colors, especially in unstable lines. This can also be explained by competition. One color can outcompete, and kill off other colors. This is the most likely scenario. This happens fairly often.

The best thing to do will be to only plant like types with like, and keep them in separate beds that cannot be accessed by one another to prevent this in the future.

Q. Small fuzzy caterpillars on my canna

The fuzzy caterpillars are about one quarter inch in length. They are cream in color and are eating the life out of the leaves. How do I get rid of them?

You can eradicate caterpillars with Bt, a biological control spray and not a poison. The caterpillar has to ingest the material when feeding on the leaf. The timing is critical as is good coverage. A repeat spray is often needed.
For a quicker knockdown use insecticidal soap, which you can purchase or make your own.

I'm sorry, but your photo did not come through. I won't be able to identify the issue.

It could be a fungus, insect, seed pod, or many other things, and without seeing it can be very difficult to pin down.

Q. Tropical canna

I ordered tropical canna from a nursery book, planted it just like it said. Plant is about 6 inches tall and never bloomed. Is watered twice a week, full sun. So what is the problem with it?

It may take several years to see blooms from a single small plant. They will get to between 3 and 10 feet tall before you will see blooms.
