"Oval-leaf Milkweed is one of the very few woodland milkweeds that grows with morning sun and afternoon shade or filtered sun all day long. It is a great milkweed for rock gardens with sandy soil. It grows from 1-2 feet tall. Oval-leaf Milkweed is a petite plant with creamy white flowers." — Bobby Gendron

Growing Instructions: Start Oval-leaf Milkweed seeds outdoors in late November. Pick a location with morning sun or filtered sun and prepare soil for good drainage, if needed. Plant seeds 1/8" deep and 18” apart, using 3 seeds per hole. Water once, and then allow the winter rain and/or snow to provide moisture until the spring. The seeds will germinate 10 - 20 days after the danger of nighttime freezing has past. Once the seedlings reach 1", thin out so you have individual plants spaced 18” apart. Water regularly allowing the soil to go nearly dry between each watering. Fertilize monthly in the summer with a general purpose fertilizer. If you prefer to plant the seeds outdoors in the spring, read our detailed instructions on cold moist stratification.
