Today's Saturday challenge is: "Zimmerpflanze / Houseplant"

Aerial roots are roots above the ground. They are almost always adventitious. They are found in diverse plant species, including epiphytes such as orchids. In the wild these adventitious roots absorb rainwater for moisture and use nutrients from decaying insects or leaves for fertilizer.

I have had this orchid for nine years and pay it scant attention except when it is flower. It flowered from November last year to March of this year and seems to thrive on neglect. It only seems to flower every two years.
