How to Grow Crowpoison


Crow Poison or Nothoscordum bivalve is a perennial herb. It grows to be 6 to 12 inches tall and blooms in the late winter or early- to mid-spring. The flowers are white or near white in color, with yellow orange anthers. They are 1/2-inch across and grow in clusters, along stalks that are 8 to 16 inches tall. The leaves are at the plant base and measure about an 1/8 inches wide but can be as long as 15 inches. Certain parts of it are poisonous if ingested. Crow Poison looks like wild onion but doesn't have the onion or garlic smell.

Step 1

Select a planting area or container that's in full sun or sun to partial shade. Remove weeds and debris with weedkiller or hand tools.

Step 2

Check the soil's pH level. Crow Poison does best in mildly alkaline to acidic soil -- from a 5.6 pH level to 7.8.

Step 3

Know that Crow Poison can be found in many types of soil, from clay to sand. Add compost to the soil to ensure the plant gets the nutrients it needs. Mix it in to make an even blend.

Step 4

Dig holes for the bulbs. Place them with their root sides up. If you can't tell which is the root side, put them on their sides and they will shift.

Step 5

Water the bulbs regularly until they sprout.
