Western Sand Milkweed Seeds
Grow Western Sand Milkweed to attract Monarch butterflies and feed the hungry Monarch caterpillars! This milkweed loves sandy soil and is drought tolerant once established. This is one of the shorter milkweeds and is native in the southwest from Texas up to South Dakota.
The western sand milkweed seeds need 30-60 days of cold stratification (We had success with just 30 days). You may directly sow the seeds in the fall or use artificial cold stratification if your winter isn’t long enough. After stratification, plant the seeds about 1/8″ deep. If starting seeds inside, keep the soil slightly moist. Plant in a sunny area about 1 foot apart. The Western Sand Milkweed loves sandy soil and is drought tolerant.

To help the population of Monarchs, plant native milkweed. The Western Sand Milkweed has a limited native range, and may be hard to identify in the wild. Add this milkweed to your butterfly garden and make the Monarch caterpillars happy. We would love to see photos of your plants with Monarchs all around. Share with us and other butterfly lovers.
