Butterfly Milkweed just so happens to be a beautiful flower that has long suffered from an unfortunate name. Often known in old-fashioned circles as "Butterfly Weed", it is also sometimes referred to by the more marketing-savvy as "Butterfly Flower". This beautiful flower is cherished by serious wild gardeners. For best success with this perennial seed, we recommend Fall Planting. For Spring Planting, seeds should be cold stratified prior to sowing.

Growing Asclepsias

Asclepias, also known as milkweed or pleurisy root, is a genus of flowering perennials native to Northern and Central America.  It was named after the Greek God of healing, Asclepius, because it was once thought to have healing properties. 

Asclepias is known of for its milky sap, its complex flowers and as the monarch butterfly’s only food source.  It attracts bees and butterflies and is frequently used in butterfly gardens and flower gardens or as borders. Asclepias blooms from July to August and grows to a height of 28 to 40 inches.

Planting Asclepias is a little tricky, but once it has been established, it is easy to maintain.  You can directly sow the seeds outside once the threat of the frost has passed and soil has warmed, however, it is recommended that you start them inside 10 to 12 weeks prior to the last frost.  (Especially if you wish to attract monarch butterflies.)

Begin by gently pressing the seeds into moist, but not overly wet soil.  Leave the pots with the seeds in the refrigerator for 3 weeks.  Keep the seeds moist, but not so wet that they begin to mold.  The best way to do this is to place all the pots into a tray and fill the tray with water.  The soil will draw the water up and keep the seeds moist.  Alternatively, you can mist the seeds.

Remove the seeds from the fridge after three weeks.  Use a grow light once they are out of the fridge.  Continue to keep the seeds moist.  The seeds should germinate in 14 to 21 days once they are out of the fridge.  Due to the delicate taproot, do not allow the plant roots to outgrow their container.  The plant will begin to deteriorate quickly. 

Once the ground outside has warmed and the plants have developed a set of true leaves, you can plant them outside.  First “harden them off” by gradually letting them spend more and more time outside so they can get used to the abrupt “climate change.”

Find a sunny spot in your garden with well-draining soil.  Asclepias can tolerate a variety of soils from sandy to poor soil and mild acidity.  It also tolerates heat.  Space plants 12 to 24 inches apart.  Asclepias matures in about 90 days.

Visit our page on germination tips.

To encourage a second blooming, deadhead the plant.  New flowers should appear about a month later.  Asclepias readily self-seeds, but is not an invasive plant.  If you wish to curb its spread, simply remove all the flowers or seed pods before they have a chance to fully develop and drop their seeds.

Harvesting the flowers is easy.  Simply wait until ½ to ¾ of the flowers on the stem have opened before cutting.  Asclepias looks beautiful alone in a vase, or as part of an arrangement.
