Canna Lily 'Yellow King Humbert'

I bought these on a whim a year ago and have been very lucky with them. I'm in zone 5b and didn't realize you had to dig these up for wi...Read Morenter. I had a good 5" of mulch over the rhizomes and it has survived! Not only has it survived somehow it's managed to multiply and I have moved them to a sunnier location. What started out as 4 plants has turned into about 10 so far. Not sure if my luck will last this coming winter so if anyone can tell me how to store them please let me know.

I love my King Humberts! I bought two in the spring and I guess I have at least six now. Living in Zone 7, do I need to dig Humbert up an...Read Mored store in the refrigerator or will he overwinter okay?

Yellow King Humbert and Florence Vaughan are the same Canna. Not sure, why they come with 2 different names. Anyway, this is one Canna th...Read Moreat multiplies so fast, that before you realize it, you have hundreds of them. I started out with only one plant 3 years ago and now have several hundreds. They are taking over my yard and I can't sell them as fast as they grow. The blooms are large and beautiful, they are my earliest bloomers and the latest ones. A few of them I have planted in a bed that has a half day shade and the soil is a mix of sand and grass clippings . Didn't expect them to grow there at all, but those got over 7 feet tall. Go figure, they obviously love sand mixed with plant matter in a half shady location. I just had to divide them again, because the rhizomes would get so large and even grow out of the bordered bed into the grass. Basically I am permanently dividing them and am now running out of space.

I believe people are getting 'Yellow King Humbert' and 'Florence Vaughan' mixed up.

Including me! Not sure which one I have now.
