About Ranunculus (persian buttercup)

Layered flowers from a bunch of claw-shaped tuberous roots. Plant claws pointing down.

Depth and spacing

Typical range: 5 cm deep and 10-15 cm apart. A general rule is to plant at two to three times the height of the tuberous root; check the label for your variety. The drawing is to scale for 5 cm deep and 12.5 cm apart (the size of the organ is illustrative); try your own measurements.

When to plant

Plant in spring. Plant: 4 weeks before up to your last spring frost. These are rules of thumb for the northern hemisphere. Enter your frost dates for real dates.

Dividing and propagating

Pull the claw clusters apart after the foliage dies back; each piece needs a piece of crown.

Lifting and storing

Lift after the foliage dies, dry well and store in a cool, dry place. Soak in cool water for a few hours before planting.

Not on the ASPCA list

The ASPCA plant list has no entry we could match to this plant, so we cannot say it is safe. Keep pets from chewing it and digging up the tuberous root, and ask your vet if in doubt. Search the ASPCA list.
