How to Grow Celandine Poppy

Overview

The Celandine poppy (Stylophorum diphyllum), also called the wood poppy, is an attractive native of Illinois with yellow flowers atop plants that reach one to one and one half feet tall. It is not a common plant and it thrives only in southern Illinois, although some populations exist in Vermillion and Cook counties to the north. Although it is considered threatened in wild woodland areas, it adapts well to cultivation in gardens.

Step 1

Prepare an area for planting in fall by clearing all weeds and other unwanted plants. This poppy thrives in lightly wooded areas that have moist, rich soil, so try to emulate its natural conditions as much as possible.

Step 2

Dig in a good amount of organic compost to create the rich soil this plant needs. One or two bucketfuls of compost for every 20 square feet of planting area is sufficient.

Step 3

Scatter seeds liberally over your planting area and then sprinkle a small amount of soil lightly over the surface. You also can start seeds in pots or flats and then transplant them in the spring.

Step 4

Thin young plants to about 12 inches apart when they are four to six inches tall. If you'd like, you can transplant extra plants to another partially shady area.

Step 5

Keep the soil evenly moist throughout the summer months.

Step 6

Pick flowers for bouquets and to encourage bushiness and flower production.
