A real orange crown
Silk Plant
The Dutch name for the asclepias is the silk plant. This name is given because of the silk that is attached to the seeds. When this seedbox opens, the silk comes into view. This is a property all asclepias have.
A Royal Crown
Asclepias Beatrix makes no exception. The fact that the asclepias Beatrix is the queen of the asclepias does not really need any explanation. If you look at the flower of this beauty you do not have to have much imagination to see a real crown here. And if you are Dutch, and this crown is orange, you automatically have to think of the Dutch royal house.
