Why did Helen Martins plant Queen of the Night plants?

Helen Martins, the creator of the Owl House in Nieu Bethesda, South Africa, was known for her eccentricity and unique artistic vision. However, there isn't specific documented evidence as to why she planted Queen of the Night plants.

One possible reason could be the symbolic nature of these plants. The Queen of the Night, also known as the Night-blooming Cereus, is a type of cactus that blooms rarely and only at night. This could be seen as a metaphor for Helen's own life and art, which was largely misunderstood and unappreciated during her lifetime, but bloomed in its own unique way.

Another reason could be the aesthetic appeal of these plants. The Queen of the Night has a dramatic, sculptural form and large, beautiful flowers. This would have appealed to Helen's artistic sensibilities and complemented the otherworldly atmosphere of the Owl House.

However, these are just speculations. The real reason why Helen Martins planted Queen of the Night plants may remain a mystery, much like many aspects of her life and work.
