ZZ Plant Flower

Do ZZ plants have flowers? If so, what do they look like? I've had this Zamioculcas zamiifolia houseplant for years and it's never flowered before until just now! 

The flower looks similar to a peace lily, with in inner stalk that's not all that attractive that emerges from a sheath or hood. Ready for some science? I looked up both the peace lily and ZZ plant on Wikipedia and sure enough both plants are members of the family Araceae, also known as the arum family or aroids. That explains the similar look - they are somewhat related. 

The stalk in the middle of the flower is known as the spadix and the hood around it is called the spathe. Both are clearly visible in this flowering ZZ plant photo that I just took. Pretty cool!

In case you are curious, the flower has no noticeable smell from what I can tell. It looks sorta alien because it's not something you see all the time on a ZZ plant. They can be cut off without really hurting the plant but I'm going to leave it.
