# How to Plant a Ranunculus Corm
Ranunculus is a vast genus of flowers, most of which grow from underground structures called tubers. The species Ranunculus bulbous, however, grows from a corm. It is a small plant better known as bulbous buttercup, and unlike other ranunculus, it is extremely aggressive and often considered a weed. If you want to grow Ranunculus bulbous -- perhaps for a sloped area of your yard that is difficult to landscape -- note that it grows well under most light and soil conditions and can become difficult to contain after a few years.

1
Cultivate the top 6 inches of the garden bed with a tiller or garden rake and add 2 to 3 inches of compost, ground bark, leaf mold or another type of organic matter. Organic matter improves soil drainage and helps create loamy, fertile soil that holds moisture well, ideal for growing Ranunculus bulbous.

2
Plant the corms with the tops about 1 inch beneath the soil, and the flat sides and the fleshy roots facing down. Space multiple ranunculus corms about 12 to 24 inches apart. They will fill in the space quickly.

3
Pack the soil gently on top of the ranunculus structures and water thoroughly with approximately 1 inch of water.
