I know what that is!!! It is a very lovely plant holder for a Venus Flytrap!

See the holes, that is for root drainage.

Just place the nice plastic thing-y in the ground and wha-lah! When the Planet Venus appears in the sky next to the moon, a fly will be trapped in the round part and it will grow and grow.

If this plant begins to talk to you and say, "FEED ME!!!" Run don't walk to your nearest astrologer...or is it astronomer...I get confused easily...

As you can see, I am no help at all. It is hot and my imagination just went to the wild side of life. Geez, plants = wild side? I need to stop now!
