|What are ranunculus? Are they a perennial?|
|Ranunculus are colorful flowers that grow from tubers and make great cut flowers. There are nearly 250 species in the Ranunculus group and the most commonly grown is R. asiaticus, the Turban Ranunculus. This type of Ranunculus is perennial in mild climates, but won't overwinter in your Minnesota climate. They would need to be overwintered in a cool but frostfree location.
Turban Ranunculus grow happily in full sunshine in average garden soil with regular watering in the spring and summer. Plant the tubers in the spring and water thoroughly, but don't water again until sprouts show. If overwatered, roots will not form and the tubers will die. Plant the tubers 6-8 inches apart and about 2 inches deep.
Ranunculus leaves are a bright, fresh green and the flowers are 3-5 inches wide, in many shades of yellow, orange, red, pink, cream and white. Large tubers may produce many 1 1/2 foot tall stalks with 1-4 blooms on each stalk. Thanks for writing!
