Detailed Description for Asclepias

Asclepias purpurascens shares similar characteristics to Asclepias syriaca, except for their umbel of flowers. As the name purpurascens eludes, these flowers produce a gorgeous purple/fuchsia hue that vibrates against the tall meadow grasses it grows among. Also unlike Asclepias syriaca, it is not an aggressive seeder, which makes it a friendlier option for home gardens. 

Asclepias purpurascens and Asclepias syriaca are known to to genetically cross-pollinate. This leads to hybrids which do not always carry over vibrant purple flowers.
