The Q&A Archives: Ranunculus Plants

Question: I recently purchased a bunch of 4" Ranunculus plants. In the past, when I searched for information on these plants, I learned that they are bulbs. Now, I've come across conflicting information stating that Ranunculus bulbs should be planted now (in the Spring) although it had been my previous understanding that they are Spring-blooming bulbs that should be planted in the Fall. Among all this, I never found any information on purchasing and planting them as plants. I absolutely adore Ranunculus and hope to have a nice plot of them come back each Spring. What do I need to know (and do) to make this happen?

Answer: Perhaps the confusion comes because ranunculus are tender and may have to be dug and replanted to protect them from hard frost. So, in zones 4 - 7 plant in spring, harvest in fall; in zone 8 they're hardy with a mulch (no digging necessary); and zones 9 & 10 they're completely hardy and do not need to be dug and replanted each season.

Ranunculus are actually summer bloomers although they may flower in late spring.

You can transplant yours into the garden in full sun if the soil is moist, or part shade if the soil's on the dry side. If left in the ground the "claws" (bulbs) will multiply and you can dig and divide them after the foliage dies down in the autumn.

Hope this answers your question!
