I love Ranunculus flowers. In years past I’ve bought them as potted plants at a local farm stand. This year for the price of one plant, I bought a package of ten tubers.
I read that the tubers are less brittle and easier to handle if you soak them for a few hours in water. I did this, and they plumped up nicely. I planted each one in a separate pot and put them in a sunny window.
Hopefully, in a few months I will be able to update this post with some photos of blooming Ranunculus.
