Planting DeCaen Anemone

I recently purchased some Anemone ‘DeCaen’ bulbs, but after looking on the internet I noticed that some say to plant in the fall and some say in the spring. I also noticed different planting directions. What do you advise?

The DeCaen bulbs are a type of poppy anemone (Anemone coronaria). They are native to the Mediterranean and only hardy to warmer regions of zones 8 to 10. Wait until spring to plant these tender tubers in northern gardens. Plant the tubers 2 to 3 inches deep next spring. In the meantime, keep the tubers covered with peat moss or vermiculite and stored in a cool dark place for winter.
