However, many species feast on the nectar as well, including fritillaries, painted ladies, skippers, swallowtails, question marks, and viceroys. Queens are also known to lay eggs on Asclepias. Asclepias grows nicely as a border or in a meadow. It is the perfect plant for those interested in a wild garden, as it is the perfect choice for those interested in conserving water. Another remarkable thing about Asclepias, is that it isn't susceptible to erosion.
Full sun is required, and be advised that average, loamy or sandy soil that is well drained is best.
Incarnata is known to survive dry soil, but still prefers evenly moist conditions. If you are planning to plant Asclepias from seed it is best to scatter the seeds in the fall, as the seeds need to be weathered. For best results, as with other butterfly gardens, please allow plants the opportunity to progress through two years of growth. In fact, when it comes to medicinal properties, in my recent journal on Asclepias, I gave historical evidence that the genus was previously known to treat many ailments, including cancer, heart disease and pneumonia. Just recently, the Asclepias genus was found to contain chemical compounds that double the number of cancer fighting agents.
